Hello,
I have encountered this issue a number of times when working on a clients WAN circuit after a critical outage is resolved.I run the command 'show frame pvc' to list the active frame circuits, and my screen scrolls through pages of interface entries. Why does this happen when we only have one circuit configured per site?. Below you can find the device and interface info, as well as the command output I have attached to here.
Please let me know if any other info is required, I have refrained from sharing the running-config at this time, as to not expose any confidential client data.
