Hi Adekunle,
IOS XR has a similar mechanism. You can view the commit list and its changes:
RP/0/0/CPU0:ios#show configuration commit list
Mon Mar 7 11:44:19.885 UTC
SNo. Label/ID User Line Client Time Stamp
~~~~ ~~~~~~~~ ~~~~ ~~~~ ~~~~~~ ~~~~~~~~~~
1 1000000002 cisco con0_0_CPU0 CLI Mon Mar 7 11:44:17 2016
2 1000000001 cisco con0_0_CPU0 CLI Mon Mar 7 11:43:48 2016
Above you can see two changes have been made through the CLI. Here’s what the first change looks like:
RP/0/0/CPU0:ios#show configuration commit changes 1000000001
Mon Mar 7 11:44:53.743 UTC
Building configuration...
!! IOS XR Configuration 6.0.0
interface GigabitEthernet0/0/0/0
ipv4 address 192.168.1.1 255.255.255.0
!
end
In the first change, only an IPv4 address was configured on the Gigabit interface.
Hope this helps.
Rene
