Hi,
I am somewhat new to cisco IOS. We have full T1 line terminated at cisco 2620 (IOS 12.3)with the integrated CSU/DSU. It has two interfaces FastEthernet 0/0 (LAN) and Serial 0/0 (T1). At least that's what the router shows when I execute the command 'show int'.
I've been seeing a lot of frame drops in the serial0/0 interface and CRC error. Here is what my router shows (1wd4 stat):
Input queue: 0/75/0 (size/max/drops); Total output drops: 404021
Queueing strategy: weighted fair
Output queue: 0/1000/64/404021 (size/max total/threshold/drops)
Conversations 0/130/256 (active/max active/max total)
Reserved Conversations 0/0 (allocated/max allocated)
5 minute input rate 98000 bits/sec, 88 packets/sec
5 minute output rate 606000 bits/sec, 698 packets/sec
493258 packets input, 80216893 bytes, 0 no buffer
Received 505 broadcasts, 0 runts, 0 giants, 0 throttles
2034 input errors, 540 CRC, 0 frame, 0 overrun, 0 ignored, 0 abor
3463399 packets output, 419484254 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets
0 output buffer failures, 0 output buffers swapped out
0 carrier transitions
DCD=up DSR=up DTR=up RTS=up CTS=up
My ISP asked me to check the frame type and clock source. They said it should be ESF for frame and line for clock source. Looking through IOS 12.3 documentation, I see one of the controllers (either E1 or T1) has these settings. But if I execute the 'show controller e1' or 'show controller t1', I see nothing or even errors. The router goes back to command prompt as if nothing is configured for E1 or T1.
So my question is where would I go to set these configs?
Thanks

Hi,
'show controller t1 0/0' should show you these settings ....

This is what I get if I type 'show controller t1 0/0'
router#show controller t1 0/0
^
% Invalid input detected at '^' marker.

But if I enter 'show controller serial 0/0', this is what I get:
router#show controller se 0/0
Interface Serial0/0

Ok, I see your problem. Try the following command: show service-module serial 0/0

This is what I got. Now I can see clock source and framing type.
router#show service-module serial 0/0

Receiver has no alarms.
Framing is ESF, Line Code is B8ZS, Current clock source is line,
Fraction has 24 timeslots (64 Kbits/sec each), Net bandwidth is 1536 Kbits/sec.
Last module self-test (done at startup): Passed

Thanks.
So why didn't 'show controller t1 0/0' didn't work. Thanks
