I've got 2 t1's bonded together via MLPPP on a PA-MC-T3 card in a 7204vxr for our backbone connection. While running extended ping tests on the remote interface accross the link, I'll get decent results between 3-6 ms but every 30-45 seconds it will jump to over 300 ms for a couple packets. I'm not getting any input, crc or frame errors on either of the t1 serial interfaces and the multilink stats look fine to. Does anyone know if there's anything else I can check on my side before I open a trouble ticket with the telco?
Any help would greatly be appreciated.
Thanks in advance,
