Configuring ingress mappings

You can modify the ingress 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 802.1p bit to QoS ingress mappings:

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

  3. Configure DSCP to QoS ingress mappings:

    qos ingressmap ds <0-63> <0-6>

  4. Ensure the configuration is correct:

    show qos ingressmap [1p <0–7>]

    show qos ingressmap [ds <0–63>]

Variable definitions

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

Table 1. Variable definitions

Variable

Value

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

Maps the IEEE 802.1p bit to QoS level. 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 ingressmap 1p

ds <0-63> <0-6>

Maps the DS byte to QoS level. The system reserves level 7 for Network Control. To use the default configuration, use the default option in the command:

default qos ingressmap ds
