Thanks

But this doesn't say that fa0/23 is using that mapping?

With 3550's you can put frames with COS value in queue 1 on one port and
in queue 4 on another port.
COS value to queue mapping appears to be configurable globally on the
3560's. Is this correct?

        The question asks to put traffic with an ip precedence value or

        With 3550's this can be done on the interface with.
        Int fa0/23
            priority-queue out
            wrr-queue cos-map 4 5 6 7

        I then verify this by using
        sh mls qos int fa0/23 queuing

        With 3560's I have used the global command and enabled the

        mls qos srr-queue output cos-map queue 1 threshold 3 5 6 7.
        int fa0/23
            priority-queue out

        But I can not find the show command to prove that ip precedence
value or
        cos value of 5, 6 and 7 are in the priority queue.
        As the output below doesn't tell me what values are mapped to
what queue
        for this interface?

        Cat3560-1#sh mls qos int fa0/23 queueing
        FastEthernet0/23
        Egress Priority Queue : enabled
        Shaped queue weights (absolute) : 10 0 0 0
        Shared queue weights : 10 10 60 20
        The port bandwidth limit : 100 (Operational Bandwidth: 100.0)
        The port is mapped to qset : 1

        Any help?
