    Hi,

    I'm trying to apply a QoS policy which reserves a specific amount of bandwith for voice. I'm also trying to tell the gateway that the maximum available bandwidth is 10Mbps and that voice and all other traffic can use each others idle bandwidth. 

    This is what I did:

    !CAR to tell the router the max is 10Mbps
    qos car myCar hierarchi cir 10000

    !Next I create 2 classes to specify my voice traffic and all my other traffic
    traffic classifier default operator and
    if-match any
    #
    traffic classifier voice operator or
    if-match dscp ef

    !In the following behaviors, I specify that voice should have 25% of the available bandwidth and default can have all other
    traffic behavior default
    car cir 7504 hierarchy-car myCar mode and
    #
    traffic behavior voice
    car cir 2496 hierarchy-car myCar mode or

    !Next, the above is combined into a policy-map
    qos policy myPolicy
    classifier voice behavior voice
    classifier default behavior default

    !This policy is then applied to the outbound direction of the WAN interface
    interface Gigx/x
    qos apply policy myPolicy outbound

     

    !However the classifiers show as 'Failed' in the show command
    Interface: GigabitEthernetx/x
    Direction: Outbound
    Policy: myPolicy
    Classifier: voice (Failed)
    Hierarchy-car name: myCar, Mode: OR
    Classifier: default (Failed)

    This all is applied on a 5510
    Software Ver : 5510-1120P10
    PCB 1 Ver : VER.A
    FPGA Ver : 001
    BootRom Ver : 123
    CPLD 1 Ver : 003

    Any suggestions?
