Variable Definitions

The following table defines parameters for the show logging file command.

Variable

Value

alarm

Displays alarm log entries.

CPU WORD <0-100>

Filters and lists the logs according to the CPU that generated the message. Specify a string length of 0-25 characters. To specify multiple filters, separate each CPU by the vertical bar (|), for example, CPU1|CPU2.

detail

Displays CLI and SNMP logging information.

event-code WORD<0–10>

Specifies a number that precisely identifies the event reported.

module WORD<0-100>

Filters and lists the logs according to module. Specifies a string length of 0–100 characters. Categories include SNMP, EAP, RADIUS, RMON, WEB, HW, MLT, FILTER, QOS, CLILOG, SW, CPU, IP, VLAN, IPMC, and SNMPLOG. To specify multiple filters, separate each category by the vertical bar (|), for example, |FILTER|QOS.

name-of-file WORD<1-99>

Displays the valid logs from this file. For example, /intflash/logcopy.txt. You cannot use this command on the current log file, the file into which the messages are currently logged. Specify a string length of 1 to 99 characters.

If you enable enhanced secure mode, the system encrypts the entire log file. After you use the show log file name-of-file WORD<1–99> command, the system takes the encrypted log file name as input, then decrypts it, and prints the output to the screen. You can then redirect the decrypted output to a file that you can store onto the flash.

If enhanced secure mode is disabled, the system only encrypts the proprietary portion of the log file.

save-to-file WORD<1-99>

Redirects the output to the specified file and removes all encrypted information. You cannot use the tail option with the save-to-file option. Specify a string length of 1–99 characters.

severity WORD<0-25>

Filters and lists the logs according to severity. Choices include INFO, ERROR, WARNING, and FATAL. To specify multiple filters, separate each severity by the vertical bar (|), for example, ERROR|WARNING|FATAL.

tail

Shows the last results first.

vrf WORD<0–32>

Specifies the name of a VRF instance to show log messages that only pertain to that VRF.
