12.0(1)T |

|
12.2(33)SRA |
This command was integrated into Cisco IOS Release 12.2(33)SRA. |
Usage Guidelines
The regular-expression argument is case sensitive and allows for complex matching requirements. Use parenthesis to indicate a literal use of spaces. For example, | begin u indicates that the show output should begin with any line that contains a u; | begin ( u) indicates that the show output should begin with any line that contains a space and a u together (line has a word that begins with a lowercase u).
To search the remaining output of the show command, use the following command at the —More— prompt:
/regular-expression
You can specify a filtered search at any —More— prompt. To filter the remaining output of the show command, use one of the following commands at the —More— prompt:
—regular-expression
+regular-expression
When output volume is large, the search can produce long lists of output. To interrupt the output, press Ctrl—^ (Ctrl-Shift-6) or Ctrl—z.
Note 
Once you specify a filter for a show command, you cannot specify another filter at the next —More— prompt. The first specified filter remains until the more command output finishes or until you interrupt the output. The use of the keyword begin does not constitute a filter.
Because prior output is not saved, you cannot search or filter backward through prior output.
Note A few show commands that have long output requirements do not require user input at the —More— prompt to jump to the next table of output; these types of output require you to enter the same number of Ctrl-^ or Ctrl-Z combinations as there are —More— prompts to completely abort output.
Examples
The following is partial sample output of the show interface | begin command that begins unfiltered output with the first line that contains the regular expression «Ethernet.» At the —More— prompt, the user specifies a filter to show only the lines in the remaining output that contain the regular expression «Serial.»
Router# show interface | begin Ethernet

|
12.2(33)SRE |
This command was integrated into Cisco IOS release 12.(33)SRE. |
Usage Guidelines
In many cases, it is useful to filter the output of a show command to match a specific expression. Filtering provides some control over the type and amount of information displayed by the system. The show section command provides enhanced filtering capabilities by matching lines in the show command output containing specific expressions as well as matching any entries associated with those expressions. Filtering is especially useful, for example, when displaying large configuration files using the show running-configuration command or the show interfaces command.
If the include or exclude keyword is not specified, include is the default.
If there are no associated entries for an expression, then only the line matching the expression is displayed.
Examples
The following examples compare the filtering characteristics of the show running-config | include command with the show running-config | section command. The first example gathers just the lines from the configuration file with «interface» in them.
Router# show running-config | include interface
interface Ethernet0/0 interface Ethernet1/0 interface Serial2/0 interface Serial3/0
The next example uses the show command section command to gather the lines in the configuration file with «interface» in them as well as any lines associated with those entries. In this example, interface configuration information is captured.
Router# show running-config | section include interface
interface Ethernet0/0 shutdown no cdp enable
interface Ethernet1/0 shutdown no cdp enable interface Serial2/0 shutdown no cdp enable interface Serial3/0 shutdown no cdp enable

Usage Guidelines
Alignment Errors
Alignment errors are caused by misaligned reads and writes. For example, a two-byte read where the memory address is not an even multiple of two bytes is an alignment error. Alignment errors are caused by a software defect.
Alignment errors are reported in the system log and recorded by the router. Output from the show alignment command provides a record of these errors along with potentially useful traceback information. The traceback information for alignment errors can generally be decoded to reveal the function causing the alignment problems.
Spurious Memory Access Errors
Spurious memory access errors occur when a software process attempts to access memory in a restricted location. A read operation to this region of memory is usually caused when a nonexisting value is returned to a function in the software, or in other words, when a null pointer is passed to a function.
Spurious memory access errors are counted and recorded, if possible, by the software. This information is displayed with the show alignment command.
Examples
The following is sample output from the show alignment command when alignment detection is disabled. To enable alignment detection, use the enable command to enter privileged EXEC mode
Router# show alignment
Unaligned handler is disabled
Router#
The following is sample output from the show alignment command when there are no alignment or spurious memory errors:
Router# show alignment

Usage Guidelines
Interpreting the output of the show archive config differences command is dependent on the order in which the two files are configured. Each entry in the generated output list is prefixed with a unique text symbol to indicate the type of difference found. The text symbols and their meanings are as follows:
•A minus symbol (-) indicates that the configuration line exists in filename1(path) but not in filename2(path).
•A plus symbol (+) indicates that the configuration line exists in filename2(path) but not in filename1(path).
•An exclamation point (!) with descriptive comments is used to identify order-sensitive configuration lines whose location is different in filename1(path) than in filename2(path).
Examples
In this example, a diff operation is performed on the running and startup configuration files. Table 54 shows the configuration files used for this example.

Usage Guidelines
When an incremental diff operation is performed, a list of the configuration lines that do not appear in the running configuration file (in other words, configuration lines that only appear in the specified file that is being compared to the running configuration file) is generated as output. An exclamation point (!) with descriptive comments is used to identify order-sensitive configuration lines whose location is different in the specified configuration file than in the running configuration file.
Examples
In this example, an incremental diff operation is performed on the startup and running configuration files. Table 55 shows the configuration files used for this example.

Syntax Description
|
all |
Displays all configuration log entries. |
|
record-number [end-number] |
Displays the log entry by record number. If you specify a record number for the optional end-number argument, all log entries with record numbers between the values entered for the record—number and end-number arguments are displayed. Valid values for the record-number and end-number arguments range from 1 to 2147483647. |
|
user username |
Displays log entries attributed to a particular user. |
|
session session-number |
(Optional) Displays log entries attributed to a particular session. Valid values for the session-number argument range from 1 to 1000. |

Usage Guidelines
If you do not specify the all keyword, you must specify a record number with the record—number argument. You can optionally specify an end record number with the end-number argument to display a range of records. If you use the end-number argument to specify a record number that does not exist, all records after the starting record number with a record number lower than that specified with the end-number argument are displayed.
Specifying the provisioning keyword results in the display appearing as it would in a configuration file, rather than in tabular format. This output includes commands used to change configuration modes and logged configuration commands. This output can be used to set up another router if desired.
Examples
The following is sample output from the show archive log config command, which displays configuration log entry numbers 1 and 2:
Router# show archive log config 1 2
idx sess user@line Logged command
1 1 user1@console logging enable
2 1 user1@console logging size 200
Table 57 describes the significant fields shown in the display.
|
|
|
|---|---|
|
idx |
The record number of the configuration log entry. |
|
sess |
The session number associated with the configuration log entry. |
|
user@line |
The username of the user who executed the command that generated the configuration log entry. |
|
Logged command |
The command that was executed. |
The following example results in the display of all configuration log files as they would appear in a configuration file rather than in tabular format. In addition to displaying logged commands, the example shows the commands used to change configuration modes that are required to correctly apply the logged commands.
Router# show archive log config all provisioning
archive
log config
logging enable
logging size 200
The following example results in the display of memory usage statistics for the configuration log:
Router# show archive log config statistics
Config Log Session Info:
Number of sessions being tracked: 1
Memory being held: 3910 bytes
Total memory allocated for session tracking: 3910 bytes
Total memory freed from session tracking: 0 bytes
Config Log log-queue Info:
Number of entries in the log-queue: 3
Memory being held in the log-queue: 671 bytes
Total memory allocated for log entries: 671 bytes
Total memory freed from log entries:: 0 bytes
The output is self-explanatory.
The following example shows the contents of the archive log in XML format:
Router# show archive log config all contenttype xml

Usage Guidelines
Supported Platforms Other than the Cisco 7600 Series Router
The show bootvar command replaces the show boot command.
The show bootvar command allows you to view the current settings for the following variables:
•BOOT
•CONFIG_FILE
•BOOTLDR
The BOOT variable specifies a list of bootable images on various devices. The CONFIG_FILE variable specifies the configuration file used during system initialization. The BOOTLDR variable specifies the flash device and filename containing the rxboot image that ROM uses for booting. You set these variables with the boot system, boot config, and boot bootldr global configuration commands, respectively.
When you use this command on a device with multiple Route Switch Processor (RSP) cards (Dual RSPs), this command also shows you the variable settings for both the master and slave RSP card.
Cisco 7600 Series Router
The show bootvar command displays information about the BOOT environmental variable.
The command output depends on how you configure the boot statement as follows:
•If you enter the boot system flash bootflash:sup720_image command in the boot configuration, then the show bootvar command output displays the bootflash information.
•If you enter the boot system flash sup-bootflash:sup720_image command in the boot configuration, then the show bootvar command output displays the sup-bootflash information. This action is the correct way of configuring the boot statement.
The show bootvar command is available from the switch processor command-line interface (CLI) and the route processor CLI. From the switch processor CLI, the display is always bootflash. With either the bootflash or the sup-bootflash boot statement, the switch boots correctly. You should use sup-bootflash in the boot configuration statement because the image is stored in the switch processor bootflash; the route processor sees the image as sup-bootflash.
The number displayed after the image name (for example, c6sup12-js-mz.121-13.E,12) indicates the number of times that the Cisco 7600 series router tries to reboot the file before giving up.
Examples
Supported Platforms Other than the Cisco 7600 Series Router
The following is sample output from the show bootvar command:
Router# show bootvar
BOOT variable =
CONFIG_FILE variable = nvram:
Current CONFIG_FILE variable = slot0:router-config
BOOTLDR variable not exist
Configuration register is 0x0
In this example, the BOOT variable contains a null string; that is no bootable images are specified.
The CONFIG_FILE variable points to the configuration file in NVRAM as the startup (initialization) configuration. The run-time value for the CONFIG_FILE variable points to the router-configuration file on the flash memory card inserted in the first slot of the RSP card. That is, during the run-time configuration, you have modified the CONFIG_FILE variable using the boot config command, but you have not saved the run-time configuration to the startup configuration. To save your run-time configuration to the startup configuration, use the copy system:running-config nvram:startup-config command. If you do not save the run-time configuration to the startup configuration, then the system reverts to the saved CONFIG_FILE variable setting for initialization information upon reload. In this sample, the system reverts to NVRAM for the startup configuration file.
The BOOTLDR variable does not yet exist. That is, you have not created the BOOTLDR variable using the boot bootldr global configuration command.
The following example is output from the show bootvar command for a Cisco 7513 router configured for high system availability (HSA):
Router# show bootvar
BOOT variable =
CONFIG_FILE variable =
Current CONFIG_FILE variable =
BOOTLDR variable does not exist
Configuration register is 0x0
current slave is in slot 7
BOOT variable =
CONFIG_FILE variable =
BOOTLDR variable does not exist
Configuration register is 0x0
Table 60 describes the significant fields shown in the displays.

Cisco 7600 Series Router
This example shows how to display information about the BOOT environment variable:
Router# show bootvar
BOOT variable = sup-bootflash:c6sup12-js-mz.121-13.E,12
CONFIG_FILE variable =
BOOTLDR variable = bootflash:c6msfc2-boot-mz.121-13.E.bin
Configuration register is 0x2102
Standby is up
Standby has 112640K/18432K bytes of memory.
Standby BOOT variable = bootflash:c6sup12-js-mz.121-13.E,12
Standby CONFIG_FILE variable =
Standby BOOTLDR variable = bootflash:c6msfc2-boot-mz.121-13.E.bin
Standby Configuration register is 0x2102
The number displayed after the image name (for example, c6sup12-js-mz.121-13.E,12) indicates the number of times that the Cisco 7600 series router tries to reboot the file before giving up.

|
max cache size |
Maximum number of buffers from the pool of that interface that can be in the buffer pool cache of that interface. Each interface buffer pool has its own cache. These are not additional to the permanent buffers; they come from the buffer pools of the interface. Some interfaces place all of their buffers from the interface pool into the cache. In this case, it is normal for the free list to display 0. |
|
failures |
Total number of times a buffer creation failed. The failure may have occurred because of a number of different reasons, such as low processor memory, low IOMEM, or no buffers in the pool when called from interrupt context. |
|
no memory |
Number of times there has been low memory during buffer creation. Low or no memory during buffer creation may not necessarily mean that buffer creation failed; memory can be obtained from an alternate resource such as a fallback pool. |

This command was introduced in a release prior to Cisco IOS Release 11.0. |
|
12.2(33)SRA |
This command was integrated into Cisco IOS Release 12.2(33)SRA. |
Usage Guidelines
The Cisco link service (CLS) is used as the interface between data link users (DLUs), such as DLSw, LAN Network Manager (LNM), downstream physical unit (DSPU), and SNASw, and their corresponding data link circuits (DLCs) such as Logic Link Control (LLC), VDLC, and Qualified Logic Link Control (QLLC). Each DLU registers a particular service access point (SAP) with CLS, and establishes circuits through CLS over the DLC.
The show cls command displays the SAP values associated with the DLU and the circuits established through CLS.
For further information about CLS, use the Release 12.2 Cisco IOS Bridging and IBM Networking Configuration Guide.
Examples
The following is sample output from the show cls command:
IBD-4500B# show cls
DLU user:SNASW
SSap:0x04 VDLC VDLC650

The following is sample output from the show cls brief command:
IBD-4500B# show cls brief
DLU user:SNASW
SSap:0x04 VDLC VDLC650
DTE:1234.4000.0001 1234.4000.0002 04 04
DLU user:DLSWDLUPEER
DLU user:DLSWDLU
Bridging VDLC VDLC1000
Bridging VDLC VDLC650
The examples show two DLUs—SNASw and DLSw—active in the router. SNASw uses a SAP value of 0x04, and the associated DLC port is VDLC650. SNASw has a circuit established between MAC addresses 1234.4000.0001 and 1234.4000.0002 using source and destination SAPs 04 and 04. DLSw is a bridging protocol and uses VDLC1000 and VDLC650 ports. There are no circuits in place at this time.
In the output from the show cls command (without the brief argument), the values of timers and counters applicable to this circuit are displayed.

This version number is called the configuration change tracking identifier or CTID. The CTID can be used to compare configuration files to track configuration changes and take appropriate actions (for example, a configuration rollback). Config Logger can also use the CTID to determine if there have been any changes to the running-config file.
CTID makes the management system more efficient by presenting information that indicates a change has been made to the running-config file. Without CTID, the management system has to query the device for the current running-config file and then compare the results to the last known configuration to determine if a change has been made.
Examples
The following example shows that the current running-config file is version 4 and that this file was saved on June 15, 2006 at 7.572 seconds after 3:02 p.m.:
Router# show config id
version:4 time:2006-06-15T15:02:07.572Z
The following example shows that the current running-config file is version 9 and that this file was last saved on June 18, 2006 at 34.431 seconds after 6:34 p.m. The file was saved by the system and changed from Init:
Router# show config id detail

Usage Guidelines
This configuration infrastructure command assigns a version number that is updated every time the running-config file is changed. This version number is called the configuration change tracking identifier (CTID). The CTID assigns a version number to each saved version of the running-config file. The CTID can be used to compare configuration files to track configuration changes and take appropriate actions (for example, a configuration rollback). Config Logger can also use the CTID to determine if there have been any changes to the running-config file.
CTID makes the management system more efficient by presenting information that indicates a change has been made to the running-config file. Without CTID, the management system has to query the device for the current running-config file and then compare the results to the last known configuration to determine if a change has been made.

11.2 GS |
This command was added to support the Cisco 12000 series Gigabit Switch Routers. |
|
12.2(33)SRA |
This command was integrated into Cisco IOS Release 12.2(33)SRA. |
|
12.2(31)SB |
This command was integrated in Cisco IOS Release 12.2(31)SB. |
|
12.2(33)SB |
This command’ behavior was modified on the Cisco 10000 series router for the PRE3 and PRE4. |
|
12.0(33)S |
The keywords punt-sniff and punt-verbose were added in the command show controllers events for the Cisco 12000 Series Routers. |
Usage Guidelines
This information displayed by this command is of use only to technical support representatives in analyzing unexpected system failures in the field. It is documented here in case you need to provide the displayed statistics to an technical support engineer.
Cisco 10000 Series Router Usage Guidelines
In releases prior to Cisco IOS Release 12.2(33)SB, when you configure the t1 loopback remote command on the local router, the command also displays in the running-config file of the far-end router. This is due to the route processor (RP) updating an incorrect parameter when it receives the loopback event message from the line card for loopback requests from the far end.
In Cisco IOS Release 12.2(33)SB, the RP updates the correct parameter and the show controllers command correctly displays the loopback CLI commands applied on the local end and displays the loopback events and status received from the line card in response to loopback requests from the far end.
This change in behavior affects the following line cards and is documented in the CSCsm84447 caveat:
•4-port channelized STM1
•1-port channelized OC-12
•6-port channelized T3
•4-port half-height channelized T3
In Cisco IOS Release 12.2(33)SB, the output from the show controller command includes line code information for the 6-port channelized T3 line card and the 8-port E3/DS3 line card. However, because SONET line cards do not have a direct physical link at the T3 or E3 level, the output from the show controller t3 command does not include line code information.
In Cisco IOS Release 12.2(31)SB, the output from the show controller command displays line code information. The output of the show controller t3 command for SONET-based T3 also includes line code information.
Cisco 12000 Series Router Usage Guidelines
The packets processed by a line card are either sent to a route processor or a line card in the form of Cisco cells. To track the packets sent to a route processor from a line card is essential for troubleshooting. The keywords punt-sniff and punt-verbose have been added for the command show controllers events to identify the packets sent to RP from LC.
By default, the feature is enabled and packets punt to route processor are displayed using the command show controllers events punt-verbose. To view all the zero and non-zero punt counters use the command show controllers events punt-verbose all.
To clear all the line card events and counters including resetting the packets to be sniffed to zero, executing the command show controllers events clear.
Packets sent to route processor from line card can be sniffed by specifying the hexa-decimal value of the word. Packets can only be sniffed if the word along with the hexa-decimal value is specified. Specifying the location of the word, sniffs packets from the particular location. To reset the counters of packets to be sniffed to zero, execute the command show controllers events punt-sniff none.
For example, use the command show controllers events punt-sniff word1 0x60000000 to sniff packets punt to RP with the hexa-decimal value 0x60000000. As the location is not specified, it searches the entire buffer for the value 0x60000000. Packets punt to RP can also be sniffed by specifying a particular location using the command show controllers events punt-sniff word1 0x60000000 34.
Examples
Because you are executing this command on the line card, you must use the execute-on command to use the show command, or you must connect to the card using the attach command. All examples in this section use the execute-on command

12.1 |
This command was introduced. |
|
12.2(33)SRA |
This command was integrated into Cisco IOS Release 12.2(33)SRA. |
Usage Guidelines
Configuration commands can be applied to an interface from sources such as static templates, dynamic templates bound by resource pooling, dialer interfaces, AAA per-user attributes and the configuration of the physical interface. The show derived-config command displays all the commands that apply to an interface.
The output for the show derived-config command is nearly identical to that of the show running-config command. It differs when the configuration for an interface is derived from a template, a dialer interface, or some per-user configuration. In those cases, the commands derived from the template, dialer interface, and so on, will be displayed for the affected interface.
If the same command is configured differently in two different sources that apply to the same interface, the command coming from the source that has the highest precedence will appear in the display.
Examples
The following examples show sample output for the show running-config and show derived-config commands for serial interface 0:23 and dialer interface 0. The output of the show running-config and show derived-config commands is the same for dialer interface 0 because none of the commands that apply to that interface are derived from any sources other than the configuration of the dialer interface. The output for the show running-config and show derived-config commands for serial interface 0:23 differs because some of the commands that apply to serial interface 0:23 come from dialer interface 0.

Usage Guidelines
This command is not supported on Cisco 7600 series routers that are configured with a Supervisor Engine 2.
The CNS subsystem communicates with remote network applications through the CNS-event agent and follows the publish and subscribe model. An application sets itself up to receive events by subscribing to the approprate event subject name.
Examples
This example shows how to display the subject with which the diagnostic results is published:
Router# show diagnostic cns publish
Subject: cisco.cns.device.diag_results
This example shows how to display the subscribed subject:
Router# show diagnostic cns subscribe

Support for this command was introduced on the Supervisor Engine 720. |
|
12.2(33)SRA |
This command was integrated into Cisco IOS Release 12.2(33)SRA. |
Usage Guidelines
The sanity check runs a set of predetermined checks on the configuration with a possible combination of certain system states to compile a list of warning conditions. The checks are designed to look for anything that seems out of place and are intended to serve as an aid to maintaining the system sanity.
The following is a list of the checks that are run and the action taken when the condition is found:
•Checks whether the default gateways are reachable. If so, the system stops pinging.
•If a port auto-negotiates to half duplex, the system flags it.
Trunking Checks
•If a trunk port has the mode set to «on,» the system flags it.
•If a port is trunking and mode is auto, the system flags it.
•If a trunk port is not trunking and the mode is desirable, the system flags it.
•If a trunk port negotiates to half duplex, the system flags it.
Channeling Checks
•If a port has channeling mode set to on, the system flags it.
•If a port is not channeling and the mode is set to desirable, the system flags it.
•If a VLAN has a Spanning-Tree root of 32K (root is not set), the system flags it.
Spanning-Tree VLAN Checks
•If a VLAN has a max age on the Spanning-Tree root that is different than the default, the system flags it.
•If a VLAN has a fwd delay on the Spanning-Tree root that is different than the default, the system flags it.
•If a VLAN has a fwd delay on the bridge that is different than the default, the system flags it.
•If a VLAN has a fwd delay on the bridge that is different than the default, the system flags it.
•If a VLAN has a hello time on the bridge that is different than the default, the system flags it.
Spanning-Tree Port Checks
•If a port has a port cost that is different than the default, the system flags it.
•If a port has a port priority that is different than the default, the system flags it.
UDLD Checks
•If a port has UDLD disabled, the system flags it.
•If a port had UDLD shut down, the system flags it.
•If a port had a UDLD undetermined state, the system flags it.
Assorted Port Checks
•If a port had receive flow control disabled, the system flags it.
•If a trunk port had PortFast enabled, the system flags it.
•If a inline power port has any of the following states:
–denied
–faulty
–other
–off
The system flags it.
•If a port has a native VLAN mismatch, the system flags it.
•If a port has a duplex mismatch, the system flags it.
Bootstring and Config Register Checks
•The config register on the primary supervisor engine (and on the secondary supervisor engine if present) must be one of the following values: 0x2 , 0x102, or 0x2102.
•The system verifies the bootstring on the primary supervisor engine (and on the secondary supervisor engine if present). The system displays a message if the bootstring is empty.
•The system verifies that every file is specified in the bootstring. The system displays a message if the file is absent or shows up with a wrong checksum.
If only device: is specified as a filename, then the system verifies that the first file is on the device.
Assorted Checks
•The system displays a message if IGMP snooping is disabled.
•The system displays a message if any of the values of the snmp community access strings {RO,RW,RW-ALL} is the same as the default.
•The system displays a message if any of the modules are in states other than «Ok.»
•The system displays a message that lists all the tests that failed (displayed as an «F») in the show test all command.
•The system displays a message if *fast is not configured on the switch anywhere.
•The system displays a message if there is enough room for the crashinfo file on the bootflash:.
•The system displays a message if multicast routing is enabled globally but is not applied to all interfaces.
•The system displays a message if IGMP snooping is disabled and RGMP is enabled.
Examples
This example displays samples of the messages that could be displayed with the show diagnostic sanity command:
Router# show diagnostic sanity
Pinging default gateway 10.6.141.1 ....
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.6.141.1, timeout is 2 seconds:

Usage Guidelines
The availability of keywords depends on your system and platform. The command does not support SPAs on the Cisco 7200 series and on the NPE-G2 in the Cisco 7200 VXR routers.
A routine runs once a minute that reads environmental measurements from sensors and stores the output into a buffer. For shared port adapters (SPAs), the temperature and voltage sensors are read every few seconds to get environmental data. The environmental buffer is displayed on the console when you use the show environment command.
If a measurement exceeds desired margins, but has not exceeded fatal margins, a warning message is printed to the system console. The system software queries the sensors for measurements once a minute, but warnings for a given test point are printed at most once every hour for sensor readings in the warning range and once every 5 minutes for sensor readings in the critical range. If a measurement is out of line within these time segments, an automatic warning message appears on the console. As noted, you can query the environmental status with the show environment command at any time to determine whether a measurement is at the warning or critical tolerance.
A SPA is shut down when any of the SPA environment readings exceed the shutdown threshold.
If a shutdown occurs because of detection of fatal environmental margins, the last measured value from each sensor is stored in internal nonvolatile memory.
For environmental specifications, refer to the hardware installation and configuration publication for your individual chassis.
For network processor engines (NPEs), network services engines (NSEs), line cards, and modular services cards (MSCs), environmental information is recorded in the CISCO-ENVMON-MIB. SPAs are not supported by the CISCO-ENVMON-MIB. In Cisco IOS Release 12.2(20)S2 and later, the CISCO-ENTITY-SENSOR-MIB supports environmental information for SPAs, as well as NPEs, NSEs, line cards, and MSCs.
If the Cisco 12000 series GSR exceeds environmental conditions, a message similar to the following is displayed on the console:
%GSR_ENV-2-WARNING: Slot 3 Hot Sensor Temperature exceeds 40 deg C;
Check cooling systems
Note Blower temperatures that exceed environmental conditions do not generate a warning message.
You can also enable Simple Network Management Protocol (SNMP) notifications (traps or informs) to alert a network management system (NMS) when environmental thresholds are reached using the snmp-server enable traps envmon and snmp-server host global configuration commands.
Whenever Cisco IOS software detects a failure or recovery event from the DRPS unit, it sends an SNMP trap to the configured SNMP server. Unlike console messages, only one SNMP trap is sent when the failure event is first detected. Another trap is sent when the recovery is detected.
Cisco AS5300 DRPS software reuses the MIB attributes and traps defined in CISCO-ENVMON-MIB and CISCO-ACCESS-ENVMON-MIB. CISCO-ENVMON-MIB is supported by all Cisco routers with RPS units, and CISCO-ACCESS-ENVMON-MIB is supported by the Cisco 3600 series routers.
A power supply trap defined in CISCO-ENVMON-MIB is sent when a failure is detected and when a failure recovery occurs for the following events: input voltage fail, DC output voltage fail, thermal fail, and multiple failure events.
A fan failure trap defined in CISCO-ENVMON-MIB is sent when a fan failure or recovery event is detected by Cisco IOS software.
A temperature trap defined in CISCO-ACCESS-ENVMON-MIB is sent when a board over-temperature condition is detected by Cisco IOS software.
CISCO-ACCESS-ENVMON-MIB also defines an over-voltage trap. A similar trap is defined in CISCO-ENVMON-MIB, but it requires the ciscoEnvMonVoltageStatusValue in varbinds. This value indicates the current value of the voltage in the RPS. With Cisco AS5300 RPS units, the current voltage value is not sent to the motherboard.
CISCO-ENVMON-MIB is extended to add a new enumerated value, internalRedundant(5), for MIB attribute ciscoEnvMonSupplySource. This is used to identify a RPS unit.
Examples
Cisco ASR 1000 Series Routers
In the following example, the show environment all command displays system temperature, voltage, fan, and power supply conditions. (It does not display environmental information for SPAs.) The State column in show environment all output should show «Normal» except for fans where it indicates fan speed. A fan speed of 65% is normal.

Sample Point |
This is the area for which temperature or system voltage thresholds are displayed. |
|
LowShut |
This is the LowShut voltage threshold. If the voltage value is below the LowShut threshold, the router shuts down. Note |
|
LowCrit |
This is the low critical voltage threshold. If the voltage value is below the LowCrit threshold, a critical message is issued for an out-of-tolerance voltage value. The system continues to operate. However, the system is approaching shutdown. Note |
|
LowWarn |
The LowWarn temperature threshold and LowWarn voltage threshold are not checked and the threshold information is not displayed on the NPE-G2. |
|
HighWarn |
This is the HighWarn temperature threshold. If the temperature reaches the HighWarn threshold, a warning message is issued for an out-of-tolerance temperature value. The system continues to operate, but operator action is recommended to bring the system back to a normal state. Note |
|
HighCrit |
This is the HighCrit temperature or voltage threshold. If the temperature or voltage reaches the HighCrit level, a critical message is issued. The system continues to operate. However, the system is approaching shutdown. Note |
|
HighShut |
This is the HighShut temperature or voltage threshold. If the temperature or voltage level reaches or exceeds the HighShut value, a Shutdown message is issued and the router shuts down. |
|
NPE Inlet 44C/111F 59C/138F |
These are the HighWarn and HighCrit temperature thresholds, respectively, for the NPE Inlet. If the NPE Inlet temperature value reaches the HighWarn (44C/111F) and HighCrit (59C/138F) levels, warning and critical messages, respectively, are issued. If the value reaches 44C/111F or greater, you receive a warning message indicating HighWarn. The system continues to operate, but operator action is recommended to bring the system back to a normal state. If the value reaches 59C/138F or greater, you receive a critical (HighCrit) message instead, that indicates the system continues to operate, but the system is approaching shutdown. Note |
|
NPE Outlet 49C/120F 64C/147F |
These are the HighWarn and HighCrit temperature thresholds, respectively, for the NPE Outlet. If the NPE Outlet temperature value reaches the HighWarn (49C/120F) and HighCrit (64C/147F) levels, warning and critical messages, respectively, are issued. If the value reaches 49C/120F or greater, you receive a warning message indicating HighWarn. The system continues to operate, but operator action is recommended to bring the system back to a normal state. If the value reaches 64C/147F or greater, you receive a critical (HighCrit) message instead that indicates the system continues to operate, but the system is approaching shutdown. Note |
|
CPU Die 75C/167F 85C/185F |
These are the HighWarn and HighCrit temperature thresholds, respectively, for the CPU Die. If the CPU Die temperature value reaches the HighWarn (75C/167F) and HighCrit (85C/185F) levels, warning and critical messages, respectively, are issued. If the value reaches 75C/167F or greater, you receive a warning message indicating HighWarn. The system continues to operate, but operator action is recommended to bring the system back to a normal state. If the value reaches 85C/185F or greater, you receive a critical (HighCrit) message instead, that indicates the system continues to operate, but the system is approaching shutdown. Note |
|
System shutdown for NPE Inlet is 80C/176F |
This is the HighShut temperature threshold for the NPE Inlet. If the temperature reaches or exceeds 80C/176F, a Shutdown message is issued and the NPE Inlet area is shut down. |
|
System shutdown for NPE Outlet is 84C/183F |
This is the HighShut temperature threshold for the NPE Outlet. If the temperature reaches or exceeds 84C/183F, a Shutdown message is issued and the NPE Outlet area is shut down. |
|
System shutdown for CPU Die is 100C/212F |
This is the HighShut temperature threshold for the CPU Die. If the temperature reaches or exceeds 100C/212F, a Shutdown message is issued and the CPU Die area is shut down. |

15 of 15 soft shutdowns remaining |
When the temperature increases above the «board shutdown» level, a soft shutdown occurs (that is, the cards are shut down, and the power supplies, fans, and CI continue to operate). When the system cools to the restart level, the system restarts. The system counts the number of times this occurs and keeps the up/down cycle from continuing forever. When the counter reaches zero, the system performs a hard shutdown, which requires a power cycle to recover. The soft shutdown counter is reset to its maximum value after the system has been up for 6 hours. |

|
12.2(33)SRA |
This command was integrated into Cisco IOS Release 12.2(33)SRA. |
Usage Guidelines
If you can configure a VLAN access control list (VACL) on the port before you configure CBAC, the status displayed is INACTIVE; otherwise, it is ACTIVE. If policy feature card (PFC) resources are exhausted, the command displays BRIDGE and is followed by the number of failed currently active NetFlow requests that have been sent to the MSFC2 for processing.
The show fm inspect command output includes this information:
•interface:—Interface on which the internet protocol (IP) inspect feature is enabled
•(direction)—Direction in which the IP inspect feature is enabled (IN or OUT)
•acl name:—Name that is used to identify packets being inspected
•status:—(ACTIVE or INACTIVE) displays if HW-assist is provided for this interface+direction (ACTIVE=hardware assisted or INACTIVE)
The optional detail keyword displays the ACEs that are part of the ACL that is used for IP inspect on the given interface direction.
Examples
This example shows how to display the list and status of CBAC-configured ACLs and ports:
Router> show fm inspect
interface:Vlan305(in) status :ACTIVE
acl name:deny
interfaces:
Vlan305(out):status ACTIVE

show fm interface {interface type mod/port | null interface-number | port-channel number | vlan vlan-id}
Syntax Description
|
type |
Interface type; possible valid values are ethernet, fastethernet, gigabitethernet, tengigabitethernet, port-channel, pos, atm, null, tunnel, and ge-wan. |
|
mod/port |
Module and port number. |
|
null interface-number |
Specifies the null interface; the valid value is 0. |
|

|
12.2(33)SRA |
This command was integrated into Cisco IOS Release 12.2(33)SRA. |
Usage Guidelines
The pos, atm, and ge-wan keywords are supported on Cisco 7600 series routers that are configured with a Supervisor Engine 2.
The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module that are used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module that is installed in a 13-slot chassis, valid values for the module number are from 1 to 13 and valid values for the port number are from 1 to 48.
The port-channel number values from 257 to 282 are supported on the CSM and the FWSM only.

Поскольку операционная система Cisco IOS очень мощная и гибкая, её конфигурирование может стать достаточно трудоёмким процессом, поэтому знать основные команды крайне необходимо. В этой статье мы рассмотрим 10 основных команд, которые могут пригодиться во время выполнения настройки или диагностики устройств.
10 команд, которые должен знать каждый пользователь Cisco IOS
№1: “?”
На первый взгляд использование ? для вызова помощи кажется достаточно простым. Однако Cisco IOS кардинально отличается от других операционных систем в плане использования команды помощи. Поскольку Cisco IOS – это операционная система с командным интерфейсом, существуют тысячи команд для настройки и управления, а использование ? поможет сэкономить немало времени.
Эту команду можно применять различными способами. Во-первых, используйте ?, если не знаете какую команду написать. Например, вы можете написать ? в командной строке для вывода всех возможных команд.
Также можно использовать ?, если вы не знаете аргумент какой-либо команды. Например, можно ввести show ip ? Если команде не нужно никаких аргументов, роутер предложит только CR (возврат каретки).
Наконец, можно использовать? для просмотра всех команд, начинающихся с определённой буквы. Например, show c? покажет все команды, начинающиеся с буквы c.
№2: show running-configuration
Команда show running—config показывает текущую конфигурацию устройства. Running-configuration – это конфигурация, загруженная в данный момент в оперативную память роутера. Когда вы вносите изменения в оборудование, как раз эта конфигурация изменяется.
Важно помнить, что конфигурация не сохраняется пока не выполнить copy running—configuration startup—configuration. Команду show running-config можно сокращать до sh run.
№3: copy running-configuration startup-configuration
Эта команда сохранит текущие модификации в настройках (running-configuration, которая хранится в RAM), в энергонезависимую RAM (NVRAM). Если внезапно исчезнет электропитание, то данные в NVRAM сохранятся. Другими словами, если вы внесёте изменения в конфигурацию роутера или перезагрузите его, не используя перед этим данную команду, то все изменения будут утеряны. Команду можно сократить до copy run start.
Команда copy также используется для копирования текущей или стартовой конфигурации на TFTP-сервер.
№4: show interface
Команда show interface отображает состояние интерфейсов маршрутизатора. Вот некоторые выводимые параметры:
- Состояние интерфейса (вкл./выкл.)
- Состояние протокола на интерфейсе
- Использование
- Ошибки
- MTU
Эта команда играет важную роль для диагностики роутера или свитча. Её также можно использовать с указанием конкретного интерфейса, например, sh int fa0/0.
№5: show ip interface
Более распространёнными, чем show interface являются команды show ip interface и show ip interface brief. Команда show ip interface предоставляет огромное количество информации о конфигурации и состоянии протокола IP и его службах на всех интерфейсах. Команда show ip interface brief даёт краткий обзор интерфейсов, включая IP-адрес, статусы Layer 2 и Layer 3.
№6: config terminal, enable, interface, and router
У роутеров Cisco есть несколько разных режимов управления, в каждом из них отображаются или изменяются определённые параметры. Очень важно уметь перемещаться между этими режимами для успешной настройки маршрутизатора.
Когда вы авторизуетесь на роутере (SSH, Telnet, Console), сначала вы попадаете в user mode (пользовательский режим, где приглашение выглядит как >). В этом режиме можно написать enable для переключения в привилегированный режим (приглашение выглядит как #). В привилегированном режиме отображается любая информация, но нельзя вносить никакие изменения. Для того, чтобы попасть в режим глобальной конфигурации введите config terminal (или config t), приглашение станет выглядеть как (config)# . В этом режиме можно изменять любые настройки. Для изменения параметра интерфейса (например, IP-адреса) переключитесь в режим конфигурирования командой interface (приглашение выглядит как (config-if)#). Помимо этого, из режима глобальной конфигурации вы можете попасть в режим конфигурации роутера с помощью команды router {protocol}. Для выхода из любого режима введите exit.
№7: no shutdown
Команда no shutdown включает интерфейс. Она используется в режиме конфигурации интерфейса. Может быть полезна при диагностике или конфигурации новых интерфейсов. Если с каким-либо интерфейсом возникла проблема, можно попробовать ввести shut и no shut. Разумеется, для того, чтобы выключить интерфейс введите shutdown. Команду можно сократить до no shut.
№8: show ip route
Команда show ip route выводит таблицу маршрутизации роутера. Она состоит из списка всех сетей, которые доступны роутеру, их метрике (приоритет маршрутов) и шлюза. Команду можно сократить до sh ip ro. Также после неё могут быть параметры, например sh ip ro ospf (показывает всю маршрутизацию OSPF).
Для очистки всей таблицы маршрутизации необходимо выполнить clear ip route *. Для удаления конкретного маршрута необходимо указать адрес сети после команды, например clear ip route 1.1.1.1.
№9: show version
Команда show version показывает регистр конфигурации (в основном настройки загрузки маршрутизатора), когда последний раз роутер загружался, версию IOS, имя файла IOS, модель устройства, а также количество оперативной и флэш-памяти. Команду можно сократить до sh ver.
№10: debug
У команды debug есть много параметров, и она не работает без них. Эта команда предоставляет детальную отладочную информацию по конкретному приложению, протоколу или службе. Например, debug ip route будет сообщать вам каждый раз, когда маршрут добавляется или удаляется из роутера.
Для
настройки сетевого оборудования в вашем
распоряжении имеются разнообразные
команды операционной системы Cisco IOS.
При
входе в сетевое устройство командная
строка имеет вид:
Switch>
Команды,
доступные на пользовательском уровне
являются подмножеством команд, доступных
в привилегированном режиме. Эти команды
позволяют выводить на экран информацию
без смены установок сетевого устройства.
Чтобы
получить доступ к полному набору команд,
необходимо сначала активизировать
привилегированный режим.
Press
ENTER to start.
Switch>
Switch>
enable
Switch#
Выход
из привилегированного режима:
Switch#
disable
Switch>
О
переходе в привилегированный режим
будет свидетельствовать появление в
командной строке приглашения в виде
знака #.
Из
привилегированного уровня можно получать
информацию о настройках системы и
получить доступ к режиму глобального
конфигурирования и других специальных
режимов конфигурирования, включая
режимы конфигурирования интерфейса,
подъинтерфейса, линии, сетевого
устройства, карты маршрутов и т.п.
Для
выхода из системы IOS необходимо набрать
на клавиатуре команду exit (выход):
Switch>
exit
Возможна
работа в следующих режимах:
—
Пользовательский режим — это режим
просмотра, в котором пользователь может
только просматривать определённую
информацию о сетевом устройстве, но не
может ничего менять. В этом режиме
приглашение имеет вид:
Switch>
—
Привилегированный режим— поддерживает
команды настройки и тестирования,
детальную проверку сетевого устройства,
манипуляцию с конфигурационными файлами
и доступ в режим конфигурирования. В
этом режиме приглашение имеет вид:
Switch#
—
Режим глобального конфигурирования —
реализует мощные однострочные команды,
которые решают задачи конфигурирования.
В том режиме приглашение имеет вид:
Switch(config)#
Команды
в любом режиме IOS
распознаёт по первым уникальным символам.
При нажатии табуляции IOS
сам дополнит команду до полного имени.
При
вводе в командной строке любого режима
имени команды и знака вопроса (?) на экран
выводятся комментарии к команде. При
вводе одного знака результатом будет
список всех команд режима. На экран
может выводиться много экранов строк,
поэтому иногда внизу экрана будет
появляться подсказка — More
-. Для продолжения следует нажать enter
или пробел.
Команды
режима глобального конфигурирования
определяют поведение системы в целом.
Кроме этого, команды режима глобального
конфигурирования включают команды
переходу в другие режимы конфигурирования,
которые используются для создания
конфигураций, требующих многострочных
команд. Для входа в режим глобального
конфигурирования используется команда
привилегированного режима configure. При
вводе этой команды следует указать
источник команд конфигурирования:
—
terminal (терминал),
—
memory (энергонезависимая память или файл),
—
network (сервер tftp (Trivial ftp -упрощённый ftp)
в сети).
По
умолчанию команды вводятся с терминала
консоли, например:
Switch(config)#(commands)
Switch(config)#exit
Switch#
Команды
для активизации частного вида конфигурации
должны предваряться командами глобального
конфигурирования. Так для конфигурации
интерфейса, на возможность которой
указывает приглашение
Switch(config-if)#
сначала
вводится глобальная команда для
определения типа интерфейса и номера
его порта:
Switch#conf
t
Switch(config)#interface
type port
Switch(config-if)#(commands)
Switch(config-if)#exit
Switch(config)#exit

Введение
в конфигурацию интерфейсов.
Рассмотрим
команды настройки интерфейсов сетевого
устройства.
На
сетевом устройстве Router1 войдём в режим
конфигурации:
Router1#conf
t
Router1(
config)#
2.
Теперь ми хотим настроить Ethernet интерфейс.
Для этого мы должны зайти в режим
конфигурации интерфейса:
Router1(config)#interface
FastEthernet0/0
Router1(
config-if)#
3.
Посмотрим все доступные в этом режиме
команды:
Router1(config-if)#?
Для
выхода в режим глобальной конфигурации
наберите exit. Снова войдите в режим
конфигурации интерфейса:
Router1(config)#int
fa0/0
Мы
использовали сокращенное имя интерфейса.
4.
Для каждой команды мы можем выполнить
противоположную команду, поставивши
перед ней слово no. Следующая команда
включает этот интерфейс:
Router1(config-if)#no
shutdown
5.
Добавим к интерфейсу описание:
Router1(config-if)#description
Ethernet interface on Router 1
Чтобы
увидеть описание этого интерфейса,
перейдите в привилегированный
режим
и выполните команду show interface :
Router1(config-if)#end
Router1#show
interface
6.
Теперь присоединитесь к сетевому
устройству Router 2 и поменяйте имя его
хоста на Router2:
Router#conf
t
Router(config)#hostname
Router2
Войдём
на
интерфейс
FastEthernet 0/0:
Router2(config)#interface
fa0/0
Включите
интерфейс:
Router2(config-if)#no
shutdown
Теперь,
когда интерфейсы на двух концах нашего
Ethernet соединения включены на экране
появится сообщение о смене состояния
интерфейса на активное.
7.
Перейдём к конфигурации последовательных
интерфейсов. Зайдём на Router1.
Проверим,
каким устройством выступает наш
маршрутизатор для последовательной
линии связи: оконечным устройством DTE
(data terminal equipment), либо устройством связи
DCE
(data
circuit):
Router1#show
controllers fa0/1
Если
видим
сообщение:
DCE
cable
то
наш маршрутизатор является устройством
связи и он должен задавать частоту
синхронизации тактовых импульсов,
используемых при передаче данных.
Частота берётся из определённого ряда
частот.
Router1#conf
t
Router1(config)#int
fa0/1
Router1(config-if)#clock
rate ?
Выберем
частоту
64000
Router1(config-if)#clock
rate 64000
и
включаем интерфейс
Router1(config-if)#no
shut
