E1 controller, cisco 1841....

Hi,

My cisco 1841 router does not respond anything to the command 'sho controllers e1'. It shows a 'serial 1T WAN daughter card, WIC-1T' as the result of 'sho diag' command. Recently an E1 link has been terminated on this interface but 'sho int ser0/0/0' shows 1544kbps bandwidth. Moreover, the later command also shows 'total available bandwidth 1148 kbps' as one of the line out of all the lines of the command output. We have ordered this E1 in Hong kong, just in case it has anything to do with location.

find the attachment.

Kindly assist.

The bandwidth is inherit from the type of card. This is a WIC-1T so automatically assumes you have a T1 CSU/DSU connected to it. You can change the bandwidth with the bandwidth command under the interface.

However, this affects only dynamic routing protocols or QoS, it does not reflect the actual speed of the line. The external CSU/DSU is the one where the real configuration takes place.

Thanks again for the help..
