Troubleshooting and Fault Management Commands


Cisco IOS Release 12.2

This chapter describes the commands used to troubleshoot a routing device. To troubleshoot, you need to discover, isolate, and resolve the system problems. You can discover problems with the system monitoring commands, isolate problems with the system test commands (including debug commands), and resolve problems by reconfiguring your system with the suite of Cisco IOS software commands.

This chapter describes general fault management commands. For detailed troubleshooting procedures and a variety of scenarios, see the Cisco IOS Internetwork Troubleshooting Guide publication. For complete details on all debug commands, see the Cisco IOS Debug Command Reference.

For troubleshooting tasks and examples, refer to the "Troubleshooting and Fault Management" chapter in the Release 12.2 Cisco IOS Configuration Fundamentals Configuration Guide.

For documentation of commands in Cisco IOS Release 12.2T or 12.3 mainline, see the Cisco IOS Configuration Fundamentals and Network Management Command Reference, Release 12.3.

attach

To connect to a specific line card for the purpose of executing monitoring and maintenance commands on that line card only, use the attach privileged EXEC command. To exit from the Cisco IOS software image on the line card and return to the Cisco IOS image on the GRP card, use the exit command.

attach slot-number

Syntax Description

slot-number

Slot number of the line card you want to connect to. Slot numbers range from 0 to 11 for the Cisco 12012 router and 0 to 7 for the Cisco 12008 router. If the slot number is omitted, you are prompted for the slot number.


Defaults

None

Command Modes

Privileged EXEC

Command History

Release
Modification

11.2 GS

This command was added to support the Cisco 12000 series Gigabit Switch Routers.


Usage Guidelines

You must first use the attach privileged EXEC command to access the Cisco IOS software image on a line card before using line card-specific show EXEC commands. Alternatively, you can use the execute-on privileged EXEC command to execute a show command on a specific line card.

After you connect to the Cisco IOS image on the line card using the attach command, the prompt changes to LC-Slotx#, where x is the slot number of the line card.

The commands executed on the line card use the Cisco IOS image on that line card.

You can also use the execute-on slot privileged EXEC command to execute commands on one or all line cards.


Note Do not execute the config EXEC command from the Cisco IOS software image on the line card.


Examples

In the following example, the user connects to the Cisco IOS image running on the line card in slot 9, gets a list of valid show commands, and returns the Cisco IOS image running on the GRP:

Router# attach 9

Entering Console for 4 Port Packet Over SONET OC-3c/STM-1 in Slot: 9
Type exit to end this session

Press RETURN to get started!

LC-Slot9# show ?

  cef       Cisco Express Forwarding

  users     Display information about terminal lines
  version   System hardware and software status

LC-Slot9# exit

Disconnecting from slot 9.
Connection Duration: 00:01:04
Router# 

Note Because not all statistics are maintained on the line cards, the output from some of the show commands might not be consistent.


Related Commands

Command
Description

attach shelf

Connects you to a specific (managed) shelf for the purpose of remotely executing commands on that shelf only.

execute-on slot

Executes commands remotely on a specific line card, or on all line cards simultaneously.

To clear messages from the logging buffer, use the clear logging privileged EXEC command.

clear logging

Syntax Description

This command has no arguments or keywords.

Command Modes

Privileged EXEC

Command History

Release
Modification

11.2

This command was introduced.


Examples

In the following example, the logging buffer is cleared:

Router# clear logging

Router#

Related Commands

Command
Description

logging buffered

Logs messages to an internal buffer.

show logging

Displays the state of logging (syslog).


diag

To perform field diagnostics on a line card, on the Gigabit Route Processor (GRP), on the Switch Fabric Cards (SFCs), and on the Clock Scheduler Card (CSC) in Cisco 12000 series Gigabit Switch Routers (GSRs), use the diag privileged EXEC command. To disable field diagnostics on a line card, use the no form of this command.

diag slot-number [halt | previous | post | verbose [wait] | wait]

no diag slot-number

Syntax Description

slot-number

Slot number of the line card you want to test. Slot numbers range from 0 to 11 for the Cisco 12012 and 0 to 7 for the Cisco 12008 router. Slot numbers for the CSC are 16 and 17, and for the FSC are 18, 19, and 20.

halt

(Optional) Stops the field diagnostic testing on the line card.

previous

(Optional) Displays previous test results (if any) for the line card.

post

(Optional) Initiates an EPROM-based extended power-on self-test (EPOST) only. The EPOST test suite is not as comprehensive as the field diagnostics, and a pass/fail message is the only message displayed on the console.

verbose [wait]

(Optional) Enables the maximum status messages to be displayed on the console. By default, only the minimum status messages are displayed on the console. If you specify the optional wait keyword, the Cisco IOS software is not automatically reloaded on the line card after the test completes.

wait

(Optional) Stops the automatic reloading of the Cisco IOS software on the line card after the completion of the field diagnostic testing. If you use this keyword, you must use the microcode reload slot global configuration command, or manually remove and insert the line card (to power it up) in the slot so that the GRP will recognize the line card and download the Cisco IOS software image to the line card.


Defaults

No field diagnostics tests are performed on the line card.

Command Modes

Privileged EXEC

Command History

Release
Modification

11.2 GS

This command was added to support the Cisco 12000 series GSR.


Usage Guidelines

The diag command must be executed from the GRP main console port.

Perform diagnostics on the CSC only if a redundant CSC is in the router.

Diagnostics will stop and ask you for confirmation before altering the router's configuration. For example, running diagnostics on a SFC or CSC will cause the fabric to go from full bandwidth to one-fourth bandwidth. Bandwidth is not affected by GRP or line card diagnostics.

The field diagnostic software image is bundled with the Cisco IOS software and is downloaded automatically from the GRP to the target line card prior to testing.


Caution Performing field diagnostics on a line card stops all activity on the line card. Before the diag EXEC command begins running diagnostics, you are prompted to confirm the request to perform field diagnostics on the line card.

In normal mode, if a test fails, the title of the failed test is displayed on the console. However, not all tests that are performed are displayed. To view all the tests that are performed, use the verbose keyword.

After all diagnostic tests are completed on the line card, a PASSED or TEST FAILURE message is displayed. If the line card sends a PASSED message, the Cisco IOS software image on the line card is automatically reloaded unless the wait keyword is specified. If the line card sends a TEST FAILURE message, the Cisco IOS software image on the line card is not automatically reloaded.

If you want to reload the line card after it fails diagnostic testing, use the microcode reload slot global configuration command.


Note When you stop the field diagnostic test, the line card remains down (that is, in an unbooted state). In most cases, you stopped the testing because you need to remove the line card or replace the line card. If that is not the case, and you want to bring the line card back up (that is, online), you must use the microcode reload global configuration command or power cycle the line card.


If the line card fails the test, the line card is defective and should be replaced. In future releases this might not be the case because DRAM and SDRAM SIMM modules might be field replaceable units. For example, if the DRAM test failed you might only need to replace the DRAM on the line card.

For more information, refer to the Cisco 12000 series installation and configuration guides.

Examples

In the following example, a user is shown the output when field diagnostics are performed on the line card in slot 3. After the line card passes all field diagnostic tests, the Cisco IOS software is automatically reloaded on the card. Before starting the diagnostic tests, you must confirm the request to perform these tests on the line card because all activity on the line card is halted. The total/indiv. timeout set to 600/220 sec. message indicates that 600 seconds are allowed to perform all field diagnostics tests, and that no single test should exceed 220 seconds to complete.

Command
Description

microcode reload

Reloads the Cisco IOS image on a line card on the Cisco 7000 series with RSP7000, Cisco 7500 series, or Cisco 12000 series routers after all microcode configuration commands have been entered.


exception core-file

To specify the name of the core dump file, use the exception core-file global configuration command. To return to the default core filename, use the no form of this command.

exception core-file file-name

no exception core-file

Syntax Description

file-name

Name of the core dump file saved on the server.


Defaults

The core file is named hostname-core, where hostname is the name of the router.

Command Modes

Global configuration (config)

Command History

Release
Modification

10.2

This command was introduced.


Usage Guidelines


Caution Use the exception commands only under the direction of a technical support representative. Creating a core dump while the router is functioning in a network can disrupt network operation. The resulting binary file, which is very large, must be transferred to a TFTP, File Transfer Protocol (FTP), or remote copy protocol (rcp) server and subsequently interpreted by technical personnel that have access to source code and detailed memory maps.

If you use TFTP to dump the core file to a server, the router will only dump the first 16 MB of the core file. If the router's memory is larger than 16 MB, the whole core file will not be copied to the server. Therefore, use rcp or FTP to dump the core file.

Examples

In the following example, a user configures a router to use FTP to dump a core file named dumpfile to the FTP server at 172.17.92.2 when it crashes:

ip ftp username red
ip ftp password blue
exception protocol ftp
exception dump 172.17.92.2
exception core-file dumpfile

Related Commands

Command
Description

exception dump

Causes the router to dump a core file to a particular server when the router crashes.

exception memory

Causes the router to create a core dump and reboot when certain memory size parameters are violated.

exception spurious-interrupt

Causes the router to create a core dump and reload after a specified number of spurious interrupts.

exception protocol

Configures the protocol used for core dumps.

ip ftp password

Specifies the password to be used for FTP connections.

ip ftp username

Configures the username for FTP connections.


exception dump

To configure the router to dump a core file to a particular server when the router crashes, use the exception dump global configuration command. To disable core dumps, use the no form of this command.

exception dump ip-address

no exception dump

Syntax Description

ip-address

IP address of the server that stores the core dump file.


Defaults

Disabled

Command Modes

Global configuration (config)

Command History

Release
Modification

10.3

This command was introduced.


Usage Guidelines


Caution Use the exception commands only under the direction of a technical support representative. Creating a core dump while the router is functioning in a network can disrupt network operation. The resulting binary file, which is very large, must be transferred to a TFTP, File Transfer Protocol (FTP), or remote copy protocol (rcp) server and subsequently interpreted by technical personnel that have access to source code and detailed memory maps.

If you use TFTP to dump the core file to a server, the router will only dump the first 16 MB of the core file. If the router's memory is larger than 16 MB, the whole core file will not be copied to the server. Therefore, use rcp or FTP to dump the core file.

The core dump is written to a file named hostname-core on your server, where hostname is the name of the router. You can change the name of the core file by configuring the exception core-file command.

This procedure can fail for certain types of system crashes. However, if successful, the core dump file will be the size of the memory available on the processor (for example, 16 MB for a CSC/4).

Examples

In the following example, a user configures a router to use FTP to dump a core file to the FTP server at 172.17.92.2 when it crashes:

ip ftp username red
ip ftp password blue
exception protocol ftp
exception dump 172.17.92.2

Related Commands

exception linecard

To enable storing of crash information for a line card and optionally specify the type and amount of information stored, use the exception linecard global configuration command. To disable the storing of crash information for the line card, use the no form of this command.

exception linecard {all | slot slot-number} [corefile filename | main-memory size [k | m] | queue-ram size [k | m] | rx-buffer size [k | m] | sqe-register-rx | sqe-register-tx | tx-buffer size [k | m]]

no exception linecard

Syntax Description

all

Stores crash information for all line cards.

slot slot- number

Stores crash information for the line card in the specified slot. Slot numbers range from 0 to 11 for the Cisco 12012 and 0 to 7 for the Cisco 12008 router.

corefile filename

(Optional) Stores the crash information in the specified file in NVRAM. The default filename is hostname-core-slot-number (for example, c12012-core-8).

main-memory size

(Optional) Stores the crash information for the main memory on the line card and specifies the size of the crash information. Size of the memory to store is 0 to 268435456.

queue-ram size

(Optional) Stores the crash information for the queue RAM memory on the line card and specifies the size of the crash information. Size of the memory to store can be from 0 to 1048576.

rx-buffer size

tx-buffer size

(Optional) Stores the crash information for the receive and transmit buffer on the line card and specifies the size of the crash information. Size of the memory to store can be from 0 to 67108864.

sqe-register-tx

(Optional) Stores crash information for the receive or transmit silicon queueing engine registers on the line card.

k

m

(Optional) The k option multiplies the specified size by 1K (1024), and the m option multiplies the specified size by 1M (1024*1024).


Defaults

No crash information is stored for the line card.

If enabled with no options, the default is to store 256 MB of main memory.

Command Modes

Global configuration (config)

Command History

Release
Modification

11.2 GS

This command was introduced.


Usage Guidelines

This command is currently supported only on Cisco 12000 series Gigabit Switch Routers (GSRs).

Use the exception linecard global configuration command only when directed by a technical support representative. Only enable options that the technical support representative requests you to enable. Technical support representatives need to be able to look at the crash information from the line card to troubleshoot serious problems on the line card. The crash information contains all the line card memory information including the main memory and transmit and receive buffer information.


Caution Use caution when enabling the exception linecard global configuration command. Enabling all options could cause a large amount (150 to 250 MB) of crash information to be sent to the server.

Examples

In the following example, the user enables the storing of crash information for line card 8. By default, 256 MB of main memory is stored.

12000(config)# exception linecard slot 8 


exception memory

To cause the router to create a core dump and reboot when certain memory size parameters are violated, use the exception memory global configuration command. To disable the rebooting and core dump, use the no form of this command.

no exception memory {fragment | minimum}

Syntax Description

fragment size

The minimum contiguous block of memory in the free pool, in bytes.

minimum size

The minimum size of the free memory pool, in bytes.


Defaults

Disabled

Command Modes

Global configuration (config)

Command History

Release
Modification

10.3

This command was introduced.


Usage Guidelines


Caution Use the exception commands only under the direction of a technical support representative. Creating a core dump while the router is functioning in a network can disrupt network operation. The resulting binary file, which is very large, must be transferred to a TFTP, File Transfer Protocol (FTP), or remote copy protocol (rcp) server and subsequently interpreted by technical personnel that have access to source code and detailed memory maps.

This command is useful to troubleshoot memory leaks.

The size is checked every 60 seconds. If you enter a size that is greater than the free memory, a core dump and router reload is generated after 60 seconds.

The exception dump command must be configured in order to generate a core dump file. If the exception dump command is not configured, the router reloads without generating a core dump.

Examples

In the following example, the user configures the router to monitor the free memory. If the amount of free memory falls below 250,000 bytes, the router will dump the core file and reload.

exception dump 131.108.92.2
exception core-file memory.overrun
exception memory minimum 250000

Related Commands

execute-on

To execute commands on a line card, use the execute-on privileged EXEC command.

execute-on {slot slot-number | all | master} command

Syntax Description

slot slot-number

Executes the command on the line card in the specified slot. Slot numbers can be chosen from the following ranges:

Cisco 12012 router: 0 to 11

Cisco 12008 access server: 0 to 7

Cisco AS5800 access server: 0 to 13

all

Executes the command on all line cards.

master

(AS5800 only) Executes the designated command on a Dial Shelf Controller (DSC). Do not use this option; it is used for technical support troubleshooting only.

command

Cisco IOS command to remotely execute on the line card.


Command Modes

Privileged EXEC

Command History

Release
Modification

11.2 GS

This command was introduced to support Cisco 12000 series Gigabit Switch Routers.

11.3(2)AA

Support for this command was added to the Cisco AS5800 universal access server.


Usage Guidelines

Use this command to execute a command on one or all line cards to monitor and maintain information on one or more line cards (for example, a line card in a specified slot on a dial shelf). This allows you to issue commands remotely; that is, to issue commands without needing to log in to the line card directly. The all form of the command allows you to issue commands to all the line cards without having to log in to each in turn.

Though this command does not have a no form, note that it is possible to use the no form of the remotely executed commands used in this command.


Tip This command is useful when used with show EXEC commands (such as show version), because you can verify and troubleshoot the features found only on a specific line card. Please note, however, that because not all statistics are maintained on the line cards, the output from some of the show commands might not be consistent.


Cisco 12000 GSR Guidelines and Restrictions

You can use the execute-on privileged EXEC command only from Cisco IOS software running on the GRP card.


Timesaver Though you can use the attach privileged EXEC command to execute commands on a specific line card, using the execute-on slot command saves you some steps. For example, first you must use the attach command to connect to the Cisco IOS software running on the line card. Next you must issue the command. Finally you must disconnect from the line card to return to the Cisco IOS software running on the GRP card. With the execute-on slot command, you can perform three steps with one command. In addition, the execute-on all command allows you to perform the same command on all line cards simultaneously.


Cisco AS5800 Guidelines and Restrictions

The purpose of the command is to conveniently enable certain commands to be remotely executed on the dial shelf cards from the router without connecting to each line card. This is the recommended procedure, because it avoids the possibility of adversely affecting a good configuration of a line card in the process. The execute-on command does not give access to every Cisco IOS command available on the Cisco AS5800 access server. In general, the purpose of the execute-on command is to provide access to statistical reports from line cards without directly connecting to the dial shelf line cards.


Warning Do not use this command to change configurations on dial shelf cards, because such changes will not be reflected in the router shelf.


Using this command makes it possible to accumulate inputs for inclusion in the show tech-support command.

The master form of the command can run a designated command remotely on the router from the DSC card. However, using the console on the DSC is not recommended. It is used for technical support troubleshooting only.

The show tech-support command for each dial shelf card is bundled into the router shelf's show tech-support command via the execute-on facility.

The execute-on command also support interactive commands such as the following:

router: execute-on slave slot slot ping

The execute-on command has the same limitations and restrictions as a vty telnet client has; that is, it cannot reload DSC using the following command:

Syntax Description

buffer-size

(Optional) Size of the buffer from 4096 to 4,294,967,295 bytes. The default size varies by platform.

level

(Optional) Limits the logging of messages to the buffer to a specified level. You can enter the level name or level number. See Table 55 for a list of the accepatable level name or level number keywords.

Modification

10.0

This command was introduced.

11.1(17)T

The command syntax was changed to include the level argument.


Usage Guidelines

This command copies logging messages to an internal buffer. The buffer is circular in nature, so newer messages overwrite older messages after the buffer is filled.

Specifying a level causes messages at that level and numerically lower levels to be logged in an internal buffer. See Table 55 for a list of level arguments.

Do not make the buffer size too large because the router could run out of memory for other tasks. You can use the show memory EXEC command to view the free processor memory on the router; however, this is the maximum available and should not be approached. The default logging buffered command resets the buffer size to the default for the platform.

To display the messages that are logged in the buffer, use the show logging EXEC command. The first message displayed is the oldest message in the buffer.

The show logging EXEC command displays the addresses and levels associated with the current logging setup, and any other logging statistics.

Command History

Release
Modification

11.2

This command was introduced.


Usage Guidelines

Sending syslog messages to the SNMP network management station occurs when you enable syslog traps with the snmp-server enable traps global configuration command. Because SNMP traps are inherently unreliable and much too important to lose, at least one syslog message, the most recent message, is stored in a history table on the router. The history table, which contains table size, message status, and message text data, can be viewed using the show logging history command. The number of messages stored in the table is governed by the logging history size EXEC command.

Severity levels are numbered 0 through 7, with 0 being the highest severity level and 7 being the lowest severity level (that is, the lower the number, the more critical the message). Specifying a level causes messages at that severity level and numerically lower levels to be stored in the router's history table and sent to the SNMP network management station. For example, specifying the level critical causes messages as the critical (3), alert (2), and emergency (1) levles to be saved to the logging history table.

Table 58 provides a description of logging severity levels, listed from higest severity to lowest severity, and the arguments used inthe logging history command syntax. Note that you can use the level name or the level number as the level argument in this command.

Modification

10.0

This command was introduced.


Usage Guidelines

The logging process controls the distribution of logging messages to the various destinations, such as the logging buffer, terminal lines, or syslog server. You can turn logging on and off for these destinations individually using the logging buffered, logging monitor, and logging global configuration commands. However, if the logging on command is disabled, no messages will be sent to these destinations. Only the console will receive messages.

Additionally, the logging process logs messages to the console and the various destinations after the processes that generated them have completed. When the logging process is disabled, messages are displayed on the console as soon as they are produced, often appearing in the middle of command output.


Caution Disabling the logging on command will substantially slow down the router. Any process generating system messages will wait until the messages have been displayed on the console before continuing.

The logging synchronous line configuration command also affects the displaying of messages to the console. When the logging synchronous command is enabled, messages will appear only after the user types a carriage return.

Examples

The following example shows command output and message output when logging is enabled. The ping process finishes before any of the logging information is printed to the console (or any other destination).

Usage Guidelines

The logging rate-limit command controls the output of messages from the system. Use this command if you want to avoid a flood of output messages. You can select the severity of the output messages and output rate by using the logging rate-limit command. You can use the logging rate-limit command anytime; it will not negatively impact the performance of your system and may improve the system performance by specifying the severities and rates of output messages.

You can use this command with or without the logging synchronous line configuration command. For example, if you want to see all severity 0, 1, and 2 messages, use the no logging synchronous command and specify logging rate-limit 10 except 2. By using the two commands together, you cause all messages of 0, 1, and 2 severity to print and limit the less severe ones (lower than 2) to only 10 per second.

(Optional) Specifies the message severity level. Messages with a severity level equal to or higher than this value are printed asynchronously. Low numbers indicate greater severity and high numbers indicate lesser severity. The default value is 2.

all

(Optional) Specifies that all messages are printed asynchronously, regardless of the severity level.

limit number-of-buffers

(Optional) Specifies the number of buffers to be queued for the terminal after which new messages are dropped. The default value is 20.


Defaults

This feature is turned off by default.

If you do not specify a severity level, the default value of 2 is assumed.

If you do not specify the maximum number of buffers to be queued, the default value of 20 is assumed.

Usage Guidelines

When synchronous logging of unsolicited messages and debug output is turned on, unsolicited Cisco IOS software output is displayed on the console or printed after solicited Cisco IOS software output is displayed or printed. Unsolicited messages and debug output is displayed on the console after the prompt for user input is returned. To keep unsolicited messages and debug output from being interspersed with solicited software output and prompts. After the unsolicited messages are displayed, the console displays the user prompt again.

When specifying a severity level number, consider that for the logging system, low numbers indicate greater severity and high numbers indicate lesser severity.

When a message queue limit of a terminal line is reached, new messages are dropped from the line, although these messages might be displayed on other lines. If messages are dropped, the notice "%SYS-3-MSGLOST number-of-messages due to overflow" follows any messages that are displayed. This notice is displayed only on the terminal that lost the messages. It is not sent to any other lines, any logging servers, or the logging buffer.


Caution By configuring abnormally large message queue limits and setting the terminal to "terminal monitor" on a terminal that is accessible to intruders, you expose yourself to "denial of service" attacks. An intruder could carry out the attack by putting the terminal in synchronous output mode, making a Telnet connection to a remote host, and leaving the connection idle. This could cause large numbers of messages to be generated and queued, and these messages would unlikely consume all available RAM. You should guard against this type of attack through proper configuration.

Examples

In the following example, line 4 is identified and synchronous logging for line 4 is enabled with a severity level of 6. Then another line, line 2, is identified and the synchronous logging for line 2 is enabled with a severity level of 7 and is specified with a maximum number of buffers to be 70,000.

line 4 
logging synchronous level 6
line 2
logging synchronous level 7 limit 70000

Usage Guidelines

The ping (packet internet groper) command sends ISO CLNS echo packets to test the reachability of a remote router over a connectionless Open System Interconnection (OSI) network.

The ping command sends an echo request packet to an address, then awaits a reply. Ping output can help you evaluate path-to-host reliability, delays over the path, and whether the host can be reached or is functioning.

To abnormally terminate a ping session, type the escape sequence—by default, Ctrl-^ X. You type the default by simultaneously pressing and releasing the Ctrl, Shift, and 6 keys, and then pressing the X key.

Table 63 describes the test characters that the ping facility sends.

Table 63 ping Test Characters 

Character
Description

!

Each exclamation point indicates receipt of a reply.

.

Each period indicates that the network server timed out while waiting for a reply.

U

A destination unreachable error protocol data unit (PDU) was received.

C

A congestion experienced packet was received.

I

User interrupted test.

?

Unknown packet type.

&

Packet lifetime exceeded.



Note Not all protocols require hosts to support pings. For some protocols, the pings are Cisco-defined and are only answered by another Cisco router.


Examples

After you enter the ping command in privileged mode, the system prompts for one of the following keywords: apollo, appletalk, clns, decnet, ip, novell, vines, or xns. The default protocol is IP.

If you enter a host name or address on the same line as the ping command, the default action is taken as appropriate for the protocol type of that name or address.

The optional data, df-bit, repeat, size, source, timeout, and validate keywords can be used to avoid extended ping command output. You can use as many of these keywords as you need, and you can use them in any order after the host-name or system-address arguments.

Although the precise dialog varies somewhat from protocol to protocol, all are similar to the ping session using default values shown in the following output:

Router# ping

Protocol [ip]:
Target IP address: 192.168.7.27
Repeat count [5]:

Success rate is 100 percent, round-trip min/avg/max = 1/2/4 ms

Table 64 describes the default ping fields shown in the display.

Table 64 ping Field Descriptions 

Field
Description

Protocol [ip]:

Prompts for a supported protocol. Enter appletalk, clns, ip, novell, apollo, vines, decnet, or xns. The default is IP.

Target IP address:

Prompts for the IP address or host name of the destination node you plan to ping. If you have specified a supported protocol other than IP, enter an appropriate address for that protocol here. The default is none.

Repeat count [5]:

Prompts for the number of ping packets that will be sent to the destination address. The default is 5 packets.

Datagram size [100]:

Prompts for the size of the ping packet (in bytes). The default is 100 bytes.

Timeout in seconds [2]:

Prompts for the timeout interval. The default is 2 seconds.

Extended commands [n]:

Specifies whether a series of additional commands appears.

Sweep range of sizes [n]:

Allows you to vary the sizes of the echo packets being sent. This capability is useful for determining the minimum sizes of the MTUs configured on the nodes along the path to the destination address. Packet fragmentation contributing to performance problems can then be reduced.

!!!!!

Each exclamation point (!) indicates receipt of a reply. A period (.) indicates that the network server timed out while waiting for a reply. Other characters may appear in the ping output display, depending on the protocol type.

Success rate is 100 percent

Indicates the percentage of packets successfully echoed back to the router. Anything less than 80 percent is usually considered problematic.

round-trip min/avg/max = 1/2/4 ms

Indicates the round-trip travel time intervals for the protocol echo packets, including minimum/average/maximum (in milliseconds).

service timestamps

To configure the system to time-stamp debugging or logging messages, use one of the service timestamps global configuration commands. To disable this service, use the no form of this command.

service timestamps [debug | log] [ uptime | datetime [msec] [localtime] [show-timezone] ]

no service timestamps [debug | log]

Syntax Description

debug

Indicates timestamping for debugging messages.

log

Indicates timestamping for system logging messages.

uptime

(Optional) Specifies that the time stamp should consist of the time since the system was last rebooted. For example "4w6d" (time since last reboot is 4 weeks and 6 days).

This is the default timestamp format for both debugging messages and logging messages.

The format for uptime varies depending on how much time has elapsed:

HHHH:MM:SS (HHHH hours: MM minutes: SS seconds) for the first 24 hours

DdHHh (D days HH hours) after the first day

WwDd (W weeks D days) after the first week

datetime

(Optional) Specifies that the time stamp should consist of the date and time.

The time stamp format for datetime is MMM DD HH:MM:SS, where MMM is the month, DD is the date, HH is the hour (in 24-hour notation), MM is the minute, and SS is the second.

If the datetime keyword is specified, you can optionally add the msec localtime, or show-timezone keywords.

If the service timestamps datetime command is used without addtional keywords, timestamps will be shown using UTC, without the year, without milliseconds, and without a time zone name.

msec

(Optional) Includes milliseconds in the time stamp, in the format HH:DD:MM:SS.mmm, where .mmm is milliseconds

localtime

(Optional) Time stamp relative to the local time zone.

show-timezone

(Optional) Include the time zone name in the time stamp.

Note If the localtime keyword option is not used (or if the local time zone has not been configured using the clock timezone command), time will be displayed in Universal Coordinated Time (UTC).


Defaults

No time-stamping.

If the service timestamps command is specified with no arguments or keywords, the default is service timestamps debug uptime.

The default for the service timestamps type datetime command is to format the time in Coordinated Universal Time (UTC), with no milliseconds and no time zone name.

The no service timestamps command by itself disables time stamps for both debug and log messages.

Command Modes

Global configuration (config)

Command History

Release
Modification

10.0

This command was introduced.


Usage Guidelines

Time stamps can be added to either debugging or logging messages independently. The uptime form of the command adds time stamps in the format HHHH:MM:SS, indicating the time since the system was rebooted. The datetime form of the command adds time stamps in the format MMM DD HH:MM:SS, indicating the date and time according to the system clock. If the system clock has not been set, the date and time are preceded by an asterisk (*) to indicate that the date and time are probably not correct.

Examples

In the following example, the user enables time stamps on debugging messages, showing the time since reboot:

service timestamps debug uptime

In the following example, the user enables time stamps on logging messages, showing the current time and date relative to the local time zone, with the time zone name included:

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.

The display from the show context command includes the following information:

Reason for the system reboot

Stack trace

Software version

The signal number, code, and router uptime information

All the register contents at the time of the crash

This information is useful only to your technical support representative for analyzing crashes in the field. Use this information when you read the displayed statistics to an engineer over the phone.

Modification

10.0

This command was introduced.

11.2 GS

The alarms, fans, hardware, leds, power-supply, table temperature, and voltages keywords were added for Cisco 12000 series GSRs.

11.3(6)AA

This command was expanded to monitor the RPS and board temperature for the Cisco AS5300 platform, Cisco 3600 Series routers, Cisco 7200 series routers, and the Cisco 12000 series routers.


Usage Guidelines

Once a minute a routine is run that gets environmental measurements from sensors and stores the output into a buffer. This buffer is displayed on the console when the show environment command is entered.

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.

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.

If the Cisco 12000 series 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 overtemperature condition is detected by Cisco IOS software.

CISCO-ACCESS-ENVMON-MIB also defines an overvoltage 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.

Table 79 show environment all Field Descriptions for the Cisco 7500 

Field
Description

Arbiter type 1

Numbers indicating the arbiter type and backplane type.

Power supply

Number and type of power supply installed in the chassis.

Active fault conditions:

Lists any fault conditions that exist (such as power supply failure, fan failure, and temperature too high).

Fan transfer point:

Software controlled fan speed. If the router is operating below its automatic restart temperature, the transfer point is reduced by 10 percent of the full range each minute. If the router is at or above its automatic restart temperature, the transfer point is increased in the same way.

Active trip points:

Compares temperature sensor against the values displayed at the bottom of the show environment table command output.

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.

Dbus slots:

Indicates which chassis slots are occupied.

card, inlet, hotpoint, exhaust

Temperature measurements at the inlet, hotpoint, and exhaust areas of the card. The (6) and (7) indicate the slot numbers. Dual-Route/Switch Processor (RSP) chassis can show two RSPs.

Shutdown temperature source

Indicates which of the three temperature sources is selected for comparison against the "shutdown" levels listed with the show environment table command.

Voltages (+12V, +5V, -12V, +24V, +2.5)

Voltages measured on the backplane.

Slot number of the equipment. On the Cisco 12012 router, slots 0 through 11 are the line cards, slots 16 and 17 are the clock and scheduler cards, slots 18 through 20 are the switch fabric cards, slots 24 through 27 are the power supplies, and slots 28 and 29 are the blowers.

3V (mv)

Measures the 3v power supply on the card. The 3v power supply is on the line cards, GRP card, clock and scheduler cards, and switch fabric cards.

5V (mv)

Measures the 5v power supply on the card. The 5v power supply is on the line cards, GRP card, and power supplies.

MBUS 5V (mv)

Measures the 5v MBus on the card. The 5v MBus is on all equipment.

Hot Sensor (deg C)

Measures the temperature at the hot sensor on the card. The hot sensor is on the line cards, GRP card, clock and scheduler cards, switch fabric cards, and blowers.

Inlet Sensor (deg C)

Measures the current inlet temperature on the card. The inlet sensor is on the line cards, GRP card, clock and scheduler cards, switch fabric cards, and power supplies.

48V (Volt)

Measures the DC power supplies.

AMP_48 (Amp)

Measures the AC power supplies.

Fan 0, Fan 1, Fan 2

Measures the fan speed in rotations per minute.


The following is sample output from the show environment all command for the Cisco 12008 router. Slots 0 through 7 are the line cards, slots 16 and 17 are the clock scheduler cards (the clock scheduler cards control the fans), slots 18 through 20 are the switch fabric cards, and slots 24 and 26 are the power supplies. The Cisco 12008 router does not support slots 25, 27, 28, and 29. An "NA" in the table means that no values were returned. In some cases it is because the equipment is not supported for that environmental parameter (for example, the power supplies in slots 24 and 26 do not have a hot sensor, so an NA is displayed).

Usage Guidelines

This command displays the state of syslog error and event logging, including host addresses, and whether console logging is enabled. This command also displays Simple Network Management Protocol (SNMP) configuration parameters and protocol activity.


Note Within the context of the CLI, "syslog" is an abbreviation for the system message logging process in Cisco IOS software. "Syslog" is alsp used to identify the messages generated, as in "syslog messages." Technically, the term "syslog" refers only to the process of logging messages to a remote host or hosts, but is commonly used to refer to all Cisco IOS system logging processes.


Examples

The following is sample output from the show logging command:

Router# show logging

Syslog logging: enabled
     Console logging: disabled
     Monitor logging: level debugging, 266 messages logged.
     Trap logging: level informational, 266 messages logged.
     Logging to 192.180.2.238

SNMP logging: disabled, retransmission after 30 seconds
    0 messages logged
Router#

Table 83 describes the significant fields shown in the display.

Description

Syslog logging

When enabled, system logging messages are sent to a UNIX host that acts as a syslog server; that is, syslog messages are saved to the specified server.

Console logging

Minimum level of severity required for a log message to be sent to the console. If disabled, the word "disabled" is displayed.

Monitor logging

Minimum level of severity required for a log message to be sent to a monitor terminal (not the console).

Trap logging

Minimum level of severity required for a log message to be sent to a syslog server.

SNMP logging

Displays whether SNMP logging is enabled, the number of messages logged, and the retransmission interval.


The following is sample output from the show logging summary command for the Cisco 12012 router. A number in the column indicates that the syslog contains that many messages for the line card. For example, line card in slot 9 has 1 system message, 4 warning messages, and 47 notification messages.

Modification

12.1

This command was introduced in a release prior to 12.1.


Usage Guidelines

The show memory fast command displays the statistics for the fast memory. "Fast memory" is another name for "processor memory," and is also known as "cache memory." Cache memory is called fast memory because the processor can generally access the local cache (traditionally stored on SRAM positioned close to the processor) much more quickly than main (primary) memory.

Cache = fast memory closest to processor = "processor memory"

Primary Memory = the main memory below cache.


Note The show memory fast command is a command alias for the show memory processor command. These commands will generate the same output on most platforms.

The following example shows sample output from the show memory fast and the show memory processor commands:

Release
Modification

12.0

This command was introduced.

12.2(2)T

The history keyword was added.

12.3(8)T

This command was enhanced to display Address Resolution Protocol (ARP) output.


Usage Guidelines

When you use the optional history keyword, output shows (in ASCII graphical form) the total CPU usage on the device over a period of time. Time periods are one minute, one hour, and 72 hours, displayed in increments of one second, one minute, and one hour, respectively. Maximum usage is measured and recorded every second; average usage is calculated on periods of more than one second.

Consistently high CPU utilization over an extended period of time indicates a problem and using the show processes cpu command is useful for troubleshooting. Also, you can use the output of this command in the Cisco Output Interpreter tool to display potential issues and fixes. Output Interpreter is available to registered users of Cisco.com who are logged in and have Java Script enabled.
