Configuring egress mappings

You can modify the egress mappings to change traffic priorities. However, as a best practice, use the default mappings.

Procedure

  1. Enter Global Configuration mode:

    enable

    configure terminal

  2. Configure QoS to 802.1p bit egress mappings:

    qos egressmap 1p <0-6> <0-7>

  3. Configure QoS to DSCP egress mappings:

    qos egressmap ds <0-7> WORD<1-6>

  4. Ensure the configuration is correct:

    show qos egressmap [1p <0–7>]

    show qos egressmap [ds <0–7>]

Variable Definitions

Use the data in the following table to use the qos egressmap command.

Variable

Value

1p <0-6> <0-7>

Maps the QoS level to IEEE 802.1p bit. Each QoS level has a default IEEE 1P value:

  • level 0—1

  • level 1—0

  • level 2—2

  • level 3—3

  • level 4—4

  • level 5—5

  • level 6—6

The system reserves level 7 for Network Control. To use the default configuration, use the default option in the command:

default qos egressmap 1p

ds <0-7> WORD<1-6>

Maps the QoS level to DS byte. You can specify the DSCP in either hexadecimal, binary, or decimal format. To use the default configuration, use the default option in the command:

default qos egressmap ds
