hi, i read on cisco's site that the default cos mapping for this receive queue is cos 5 mapped to queue 2, but when i do a show queuing im not seeing that mapping on the receive queue. when i try to map cos 5 to receive queue 2, i only have an option for queue id 1. anyone know what the issue is?
core.frv.ma(config-if)#rcv-queue cos-map ? <1-1> enter cos-map queue id
