Policy map using policy map

Discussion in 'Cisco' started by Geoffrey Sinclair, Jul 27, 2009.

  1. I have been given a template configuration for a DSCP based QoS.

    So the incoming traffic policy map marks the traffic accordingly, and
    then the WAN interface calls policy map S-QUEUE to decide how
    to handle the outbound traffic which in turn calls policy map QUEUE.

    policy-map S-QUEUE
    class class-default
    shape average 1048000
    service-policy QUEUE

    policy-map QUEUE
    class M-QUEUE !dscp ef
    priority 1032
    class I-QUEUE !dscp af31
    bandwidth 16
    class class-default !the rest
    fair-queue
    random-detect dscp-based

    Somehow I am stuck trying to figure out why not have the WAN
    interface use QUEUE instead of using S-QUEUE. The WAN
    bandwidth is 10Mb.

    This is a hierarchical policy map.

    The top level (parent) map applies traffic shaping
    and then the child map is applied to the4 result.
    This is the documented method of doing traffic
    shaping.
