Both but mainly a cell level issue: If you lose a cell, it will screw-up the AAL5 frame. Thus causing the frame and/or CRC errors seen in sh int. You are really moving some traffic. Is this PVC traffic going across any links that may be congested? A DS3 perhaps? Need to find where the cel

If you can take the link down it might be useful to do some loopbacks to see if you can isolate a link or equipment failure. I seem to remember seeing a procedure for that in the CCIE All-in One lab book. > -Original Message- > From: [EMAIL PROTECTED] (Katson Yeung) > [mailto:[EMAIL PROT

The CRCs indicate that a cell or multiple cells required to reconstruct the common part convergence sublayer pdu (cpcs pdu) were "lost". Thus the IP datagram(s) can not be successfully reassembled. The frame errors however indicate a SONET problem possibly at the physical layer. Judging from th

Thanks Dave, I do think it is related to cell level.. but as an exercise, I would really want to dig up the pieces the see the root cause... At least there are three possibilities If there are lost cell, there should be a lost cell warning If it is not a lost cell, but simply cell corru

I put that router connected back-to-back with another router and discover no cell loss... Only two things are diff from the lab. 1. It is now switched thru telco. (not back-to-back) 2. It is not the same MM fibre at both router to the telco ATM port. On 27 Apr 2001 17:09:00 -0400, [EMAIL PROTEC
