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

Queueing Mode In Rx direction: mode-cos
Receive queues [type = 1p1q0t]:
Queue Id    Scheduling  Num of thresholds
    1         Standard            0
    2         Priority            1

queue-limit ratios:    100[queue 1]   0[queue 2]

queue thresh cos-map
1     1      0 1 2 3 4 5 6 7
2     1

looks like WS-X6548-RJ-45 doesn't support it, which is what im using.

Congestion avoidance—If  you configure an Ethernet LAN port to trust CoS or DSCP, QoS classifies  the traffic on the basis of its Layer 2 CoS value or its Layer 3 DSCP  value and assigns it to an ingress queue to provide congestion  avoidance. Layer 3 DSCP-based queue mapping is available only on WS-X6708-10GE ports.
