atm session timeout

[ciscoenter]

hi all,

i would ask u some information about my problem. Recently i added to my network a ls1010 on top of my 7200 bras as collector for my xdsl. I noticed a strange problem on one of 7200s. Sometimes adsl goes down, cd led is still light on but it doesn't work until i don't shutdown the pvc on 7200.

I think the problem is connected to lcp timeout or something similar.

Someone can help me?

Thanks

Hello,

could be a bug in IOS, which version are you running on your 7200 ? Can you post the configs of your 7200 and the LS1010 ?

Regards,

GP
