Create a network QoS policy

Configuring and applying QoS policies other than the default policy is optional. A default network policy of the appropriate type is applied to each uplink port.

To create an network QoS policy, define the following:

• Specify a network policy ID value. The system does not dynamically assign a value.

• Include a description that provides a brief overview of policy features.

• Use egress marking and remarking to specify the egress FC to marking value (for example, IEEE 802.1p) map. Otherwise, the default values are applied:

  • remarking

    If enabled, this command remarks ALL packets that egress on the specified access uplink port. The remarking is based on the FC to marking values mapping defined under the egress node of the network QoS policy. Remarking can be enabled or disabled.

  • FC criteria

    The FC name represents an egress queue. Specify FC criteria to define the marking criteria of packets flowing through it.

  • marking value

    The marking (for example, IEEE 802.1p) value is used for all packets requiring marking that egress on this FC queue that are in-profile or out-of-profile.

• Specify ingress criteria using the following:

  • default action

    Defines the default action to be taken for packets that have an undefined dot1p bit set. The default-action specifies the FC to which such packets are assigned.

  • dot1p

    This specifies the dot1p to FC mapping for all packets. Ingress traffic that matches the specified criteria are assigned to the corresponding FC.

Use the following syntax to create a network QoS policy.

 config>qos# 
     network policy-id [network-policy-type network-policy-type]
         description description-string 
         scope {exclusive|template}
         egress
             remarking
             
             fc {be|l2|af|l1|h2|ef|h1|nc} 
                 dot1p-in-profile dot1p-priority
                 dot1p-out-profile dot1p-priority
             default-action fc {fc-name} profile {in|out}
             dot1p dot1p-priority fc {fc-name} profile {in|out}
             fc {fc-name}
                 meter {meter-id}
                 multicast-meter {id}
             meter meter-id [multipoint]
                 adaptation-rule cir {closest | max | min} pir {closest | max | min}
                 cbs {size-in-kbits}
                 mbs {size-in-kbits}
                 mode {trtcm | srtcm}
                 rate cir cir-rate-in-kbps [pir pir-rate-in-kbps]

The following commands associate a network QoS policy with the access-uplink port.

 config>port
     ethernet
         access
             uplink
                 qos network-policy-id
