I'm working on a 7204 router with multiple FR DLCIs, one for internal WAN and the other for Internet access (using VFR for routing table separation, T3 physical/18Mbps CIR). We have priority queing enabled via map-class on the subinterfaces and we aren't seeing drops on the subinterface queues. We are still seeing drops on the serial interface, though, and some voice quality complaints. My question is, should we lower the CIRs manually to match, attempt to add the service policy to the main interface (dumping FRTS), or do something else? Since I don't have visibility to what's being dropped (can't show policy-map int) I'm not sure if the drop behavior is what I'm expecting. Any help is appreciated.
