Running configuration message

Unanswered Question

Hello folks, I recently inherited some routers I noticed that on some of them I get this message when I run the show running configuration command.

Current configuration : 4097 bytes


! Last configuration change at 09:45:01 GMT Wed Nov 5 2008


Can someone please help me as to how can I configure the rest of my gear to give out this message. I think its a helpful feature in determining the last configuration change.

Thanks in advanced I appreciate it.

I have this problem too.

This will show up for all devices when you issue a "show run" provided they have had a config change since reboot. If not, you will see:

No configuration change since last restart

Your device's clock needs to be synchronized either with NTP or by using "clock set".

I am currently configuring our 2821 router and it does not show the message "! No configuration change since last restart

!" It currently shows the following:

Building configuration...

Current configuration : 7306 bytes


version 12.4

service timestamps debug datetime msec localtime show-timezone

service timestamps log datetime msec localtime show-timezone

service password-encryption

How can I make it show the last time it was updated or not like our other routers?

If you have already configured NTP, or set your clock to be authoritative, then start a new thread for your problem.


Try to set the clock on your router, also try to set the timezone. I did this with "timezone EST -5" it did not work so I used EDT -5 instead, now I can see that message. Here's the show run from my router.

TS1#sh run

JP - and Tom

Setting the timezone is nice but not essential to display the message about last config change. If you set the timezone then the message displays the time in terms of the local timezone - and with no timezone set the message will just use whatever is set as the time on the device (might be local time or might be GMT/UTC).

What is essential is for the router/switch to have authoritative time. The router/switch will believe that it has authoritative time if it has learned time via NTP OR if you have executed the clock set command.
