I have a 2600XM router fitted with NM-2W. There is a wic in slot 0 and a VWIC2-2MFT-G.703 card in slot 1. I have configured both the ports on this card. One of the ports is working perfectly but when I connect a line to another port, it shows
"Interface is up, Line protocol is down"
Controllers and interfaces for both the ports are configured identically.
Here is the config
card type e1 1 1
controller e1 1/2
framing no-crc4
channel-group 0 timeslots 1-31
controller e1 1/3
framing no-crc4
channel-group 0 timeslots 1-31
interface serial 1/2:0
bandwidth 1984
ip address xx.xx.xx.xx xx.xx.xx.xx
interface serial 1/3:0
bandwidth 1984
ip address xx.xx.xx.xx xx.xx.xx.xx
This config works perfectly for 1/3 but the link on 1/2 does not work. If we do shut/no shut on the interface, the link comes up/up but line protocol goes down after 10-15 secs. Also, I noticed that all kind of errors like input errors, codes, frame, overruns keep increasing very rapidly and also router cpu utilization goes up considerably
The same link, when connected to a modem works perfectly fine.
Keepalives are set for 10 sec
If anybody has any idea about this, please let me know
Best Regards,
Anand P. Diwakar
