I have a PIX506E and I'd like to log fw configuration changes (who logged on with which account, changed what on the PIX, who tried to log on but was unsuccessful etc.) and vpn user logons via syslog. Which trap level should I configure for this? Informational? Alert? Warning? Debug? Thanks!

    Accepted Solution

    True logging and accounting can happen only using aaa and not just syslog. Syslog helps a lot when it comes to system messages.

    Look at the AAA part at cisco site, with a radius server you can do authentication, authorization and accounting.

    The level of syslog:  Informational Alert Warning Debug
    indicates the amount of system messages which would be logged. For eg, in debug level almost all transactions for a particular event would be logged, in warning the number would be less and so on.

    So, it would least when set as  Informational and maximum when set to Debug.

    Thank you.
