I've got a cisco 1921 in a org. where we've added an extra gi interface and as long as a network cable is connected it works fine.
However if the network cable is disconnected and then reconnected the inteface doesn't start up again until I log into the router, enter config mode for the interface and issue the "shut" and "no shut" command.

HI Hement,
Please post the output of these commands:
1. Show inv
2. show diag
3. show int gi ?
4. sh run int gi ?
5. sh version
Regards

Hi,
Please find the above logs.
11-14-2013 07:02 PM
Hi Hemant,
Please put your interface to 'no keepalive'
11-14-2013 07:13 PM
However if the network cable is disconnected and then reconnected the inteface doesn't start up again until I log into the router, enter config mode for the interface and issue the "shut" and "no shut" command.
Seen this with my home 881 router.
The only solution I had was to upgrade the IOS and it went fine.

Dear All,
What Exaclty i have to do with router which can resolve my issue permamently. Please suggest me with the reason.
