Multi-link bundle performance

[tmcmillion]

I have a Mulit-link bundle with 4 T1's running on 3745 routers. I have had this link up and running for abut 2 years with no issues. Last week I started seeing performance issues that took response from 40ms to 4000ms and over 50% packet loss. The bandwidth utilization and cpu are running low and the only errors I see on the ser int are a few carrier transtions. Resetting the router on one end or the other corrects this issue temporarily. I have now gone the entire weekend without any problem but am confident this will reoccur again. Can someone give me an idea what debugs I can run to try and pinpoint this problem? or any ideas on what problem might be?

Hi

To isolate the exact reason for the performance issue would suggest to sepearate the T1s one by one and chek up the end to end response time ,drops in each of them induvidually.

Coz we did face similar kinda probs quite sometime back and found some problem with one of the E1 in that MPP bundle which was misbehaving.

BTW do revert whether the drops or mismatch in the latency happens during any particular time period like peak wkg hrs or off-peak hrs.
