We are running a dual-carrier frame environment and have noticed that we have a lot of "byte delayed" and out pkts dropped showing up on many PVCS on both ends and both carrier of our frame-network. We have tweaked Frame-Relay Traffic Maps to reflect individual carrier recommendations (ie Carrier selling OK CIR guarenteeing port speed we set MINCIR to 1/2 of a T1).
No FECNS/BECNS...the aggregation links are not oversubscribed and it appears things are dropping before they even go out...the only thing this seems to point to is either the traffic-maps or perhaps the ethernet switch where the routers terminate...but that doesnt appear to be it.
Any ideas on a good way to troubleshoot this? Buffers seem good as well
