show interface history command

Interesante :

Today I want to show a command that was introduced with IOS 15.1T. Using this command will upgrade your troubleshooting capabilities as you can (finally) look back and have some decent historical data on the interface level.


interface GigabitEthernet0/0
 bandwidth 102400
 no ip redirects
 no ip proxy-arp
 ip nbar protocol-discovery
 ip flow ingress
 ip flow egress
 load-interval 30
 duplex full
 speed 100
 media-type rj45
 history BPS
