Must it be SNMP traps?

IOS writes to syslog when someone enters the config mode (but doesn't necessarily mean the person makes a config change):

*Mar 1 17:56:48.596: %SYS-5-CONFIG_I: Configured from console by Cisco on vty0 (

That simply takes

! logging to the circular "show log" buffer, at level 5--notification

logging buffered [buffer size] notification

! logging to remote syslog server, at level 5--notification

logging trap notification

logging source-interface [interface of choice]


If you truly want to receive SNMP traps for those syslogs, you could add the global config:

snmp-server enable traps syslog

However, it's not really a good practice.

In more recent IOS releases, you could do fancier config change tracking, as outlined in this article:
