Question in CISCO 3660 router
Posted on 2004-10-19
Hey all router gurus,
I have got this cisco 3660 router and when I check the interface by clicking on 'show interface' logging into the web management , it tells "line protocol is down'.
We called At&T and they run all diagnostic tests and everything looks successful/fine..
is there any way to debug or what exactly could be the issue
Snippets of the interface
Serial2/1:1 is up, line protocol is down
Hardware is DSX1
Internet address is XXX.16.89.1/28
MTU 1500 bytes, BW 1536 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation PPP, loopback not set
Keepalive set (10 sec)
Closed: IPCP, CDPCP
All other T1 lines in the same router works fine and we are able to connect to the remote site whichever is connected to..
Any help on this will be appreciated..
