■vlan VLAN-ID qos dscp < af11 af12 af13 ... >

Usage: [no] qos dscp-map <01...63af11af12af13af21af22af23af31af32

af33af41af42af43efcs0..cs7000000000001...111111> [priority <<0-7>no-override>]

[name <str>]

Description: Define mapping between a DSCP (Differentiated-Services Codepoint) value and an 802.1p priority. The mapping is used to assign priority for IPv4 packets if a QoS classifier uses this DSCP policy as the method of traffic prioritization.

The mapping also provides the profile for inbound classification and priority assignment based on an IPv4 packet's received

IP ToS byte ONLY IF the user has also configured 'qos type-of-service diff-services'

'no qos dscp-map <codepoint>' will remove the settings for the specified codepoint from the running configuration. The priority is set to no-override and the name is deleted (the priority and name can only be removed if no QoS feature is configured to use this DSCP Policy).

'no qos dscp-map <codepoint> name' will remove the name associated with this policy, but not the policy priority.

Certain codepoints may have a default associated 802.1p priority, as part of the IETF standards for Assured Forwarding and Expedited Forwarding. These are automatically configured as follows:
