How do I get my routers to display:
"Last configuration change" and
"configuration change since..."
and if possible can I trap on these?
Thank you in advance,
To get those displays the router must be sure what date and time is. The best way to accomplish this is to run NTP and learn time from an NTP server. An alternative is to use the clock set command to set the time.
When the router has an authoritative time the display you want is automatic.
