Rahmani,

the priority-queue out interface command is a catalyst switch command,
not a router command.

        hence there is no command "priority-queue out"in Version
12.3(14)T7. for
        PQ.

        This is the message you are going to receive:
        R2(config-if)#service-policy output check
        Must remove priority-group configuration first.
        R2(config-if)#

        configuration test follows:
        IOS version: Version 12.3(14)T7
        Two routers connected via serial interface.
        encapsulation ppp

        CONFIGURATION #
        R2#show queueing priority
        Current DLCI priority queue configuration:
        Current priority queue configuration:

        List Queue Args
        1 low default
        1 high protocol http
        1 medium protocol arp

        applied it to interface serial s1/1
        priority-group 1 //comment: you will not find any direction
here. "not
        relevant".

        R2#show run inter s1/1

        Class Map match-any class-default (id 0)
           Match any

        Class Map match-any fahad (id 1)
           Match protocol http

        Then tried to apply this to interface serial 1/1 and thus
received the
        message.

        R2(config-if)#service-policy output check
        Must remove priority-group configuration first.

        The funda of Q is similar to access list, one per direction per
        interface...

        It's my understanding, and in case I am wrong, please do let me
know..

        Regards.

        Hey Guys,

        So i am bit confised about this and would appreciate some
comments
        please.

        So on the 3550/3560s, I could enable priority queueing on one
the 4
        output queues on the port by issuing the interface configuration
        command: priority-queue out

        Now, if i had configured an LLQ on an MQC Policy map and had
applied it
        to the interface, how does the two attributes affect packets
exitting
        this port please?

        I know its abit vague, but any information to incline my line of
though
        would be great....

        Thanks!!

        Sadiq
