Using Configuration Logging
You can log and view changes to the switch configuration. You can use the Configuration Change Logging
and Notification feature to track changes on a per-session and per-user basis. The logger tracks each
configuration command that is applied, the user who entered the command, the time that the command was
entered, and the parser return code for the command. This feature includes a mechanism for asynchronous
notification to registered applications whenever the configuration changes. You can choose to have the
notifications sent to the syslog.
Only CLI or HTTP changes are logged.Note
Using Command History
The software provides a history or record of commands that you have entered. The command history feature
is particularly useful for recalling long or complex commands or entries, including access lists. You can
customize this feature to suit your needs.
Changing the Command History Buffer Size
By default, the switch records ten command lines in its history buffer. You can alter this number for a current
terminal session or for all sessions on a particular line. These procedures are optional.
Beginning in privileged EXEC mode, enter this command to change the number of command lines that the
switch records during the current terminal session:
Device# terminal history [size number-of-lines]
The range is from 0 to 256.
Beginning in line configuration mode, enter this command to configure the number of command lines the
switch records for all sessions on a particular line:
Device(config-line)# history [size number-of-lines]
The range is from 0 to 256.
Recalling Commands
To recall commands from the history buffer, perform one of the actions listed in this table. These actions are
optional.
The arrow keys function only on ANSI-compatible terminals such as VT100s.Note
