Logging CLI Commands and Entry Results Using the CLI

Logging CLI Commands and Entry Results

The switch provides command logging through the command-log command. This feature allows users to

record up to 100 of the most recent commands entered through 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 (that is, it does not record

full syntax, date and time, session IP address, and entry results). For more information on command

history, refer to page 6-15.

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 6250/6450 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 through the command-log enable syntax, a file called command.log

is automatically created in the flash directory of the switch. Once enabled, configuration commands

entered on the command line are 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 is 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

directory. 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 6-18.
