When managing Cisco IOS network devices, administrators do come across occasions when they forget what recently they configured and then starts the tedious activity of comparing “show startup-config” and “show running-config”.
The comparison activity is not only tiring but also may take a long time to resolve.
Let’s say a situation where only 1 hour of downtime is given by Business to perform a small change on Cisco device and at least 30 minutes of critical time is utilized by administrator in comparing and finding what the changes were performed.
Alas … indeed a nightmare.
So here is the command which can address the comparison vows –
Contextual Config Diffs:
interface FastEthernet0/1
+no ip address
+shutdown
interface FastEthernet0/1
-ip address 192.168.12.1 255.255.255.0
-router eigrp 1
-network 192.168.12.1 0.0.0.0
-no auto-summary
