When you activate a configuration, you want to include a short message that describes the changes you made.
Include a comment when you activate the configuration:
aviva@router1# commit comment "turned on telnet"
It's good practice to include a short description of the changes you made to each version of a configuration file so you can keep a history of configuration changes. You do this by using the comment option with the commit command.
To track down what changed in the configuration and when, you can review the comments:
aviva@router1> show system commit 0 2005-03-31 20:26:16 UTC by aviva via cli turned on telnet 1 2005-03-31 11:12:28 UTC by aviva via cli set host gildor facility-override local4
