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.
Note: Only CLI or HTTP changes are logged.

Configuring the 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 as described in these sections:


Recalling Commands, page 13

Disabling the Command History Feature, page 13

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:
Switch# terminal history
