As stated in the subject, I have seen this couple times that all PVCs on the same physical interface (e.g. s0) were reseted, but could not find anything in the log showing the status changing of s0. Typically, there should be something in the log, such as "interface s0 status down...." and ".....up", as well as "protocol down / up". But I swear, I didn't see it at all in the log in some cases. Log is not full, it listed events before the PVC reset.
Q1: Could PVCs reset while the interface is up? What's causing this? LMI error? Any command can show this?
Q2: Could it be the log missed the event so didn't record the status changing of s0?
