Logging CLI Commands and Entry Results
OmniSwitch 6800/6850/9000 switches provide command logging via the command-log command. This
feature allows users to record up to 100 of the most recent commands entered via Telnet, Secure Shell, and
console sessions. In addition to a list of commands entered, the results of each command entry are
recorded. Results include information such as whether a command was executed successfully, or whether
a syntax or configuration error occurred.
Note. The command history feature differs from the command logging feature in that command history
buffers up to 30 of the most recent commands. The command information is not written to a separate log
file. Also, the command history feature includes only general keyword syntax (i.e., it does not record full
syntax, date and time, session IP address, and entry results). For more information on command history,
refer to
page 5-13 .
Refer to the sections below for more information on configuring and using CLI command logging. For
detailed information related to command logging commands, refer to the
OmniSwitch CLI Reference
Guide .
Enabling Command Logging
By default, command logging is disabled . To enable command logging on the switch, enter the following
command:
-> command-log enable
When command logging is enabled via the command-log enable syntax, a file called command.log is
automatically created in the switch’s flash directory. Once enabled, configuration commands entered on
the command line will be recorded to this file until command logging is disabled.
The command.log file has a 66402 byte capacity. This capacity allows up to 100 of the most recent
commands to be recorded. Because all CLI command logging information is archived to the
command.log file, command history information will be lost if the file is deleted.
Note. The command.log file cannot be deleted while the command logging feature is enabled. Before
attempting to remove the file, be sure to disable command logging. To disable command logging, refer to
the information below.
Disabling Command Logging
To disable the command logging, simply enter the following command:
-> command-log disable
Disabling command logging does not automatically remove the command.log file from the flash direc-
tory. All commands logged before the command-log disable syntax was entered remains available for
viewing. For information on viewing logged commands, along with the command entry results, refer to
“Viewing Logged CLI Commands and Command Entry Results” on page 5-16 .
