Serial 0/0 Down and Line Protocol Down

Recommended Posts

Set bandwith on connecting interfaces on both routers, same value on each e.g.:

 

interface serial x/x

bandwidth 56

Thanks for your help. Still no soloution. Bought another Cisco 2600 Router, to replace what i thought was not working correctly, however i'm still getting the same problem. Could it be my serial cables?

 

The problem is when trying to connect RouterA (DCE) to Router B (DTE) with a Serial cable.

 

Both routers display int s0/0 as down down.

 

Attached is the Network Topology and .txt files displaying show commands on both routers!

 

Regards,

Rich

No idea, on the face of it, it appeared to only go in one way. Then i google my error messages etc, encountered a forum with someone who had a similar problem and someone suggested to turn cables around, and ping! lol

 

they appear identical both sides, but sorted now anyway!
