We been seeing tons of Line Code Violations and Path Code Violations on our T1 (frame relay). Telco has tested the circuit a few times, it's clean. Telco says we are getting hit with tons of traffic causing the Line Code Violations and Path Code Violations.
We have replaced the cabling and T1 card.
Also, whenever this happens, the router stops responding and we have to reboot it. It has happened a few times and at the same time.
