Description: Dene 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 classier uses
this DSCP policy as the method of trafc prioritization.
The mapping also provides the prole for inbound classication
and priority assignment based on an IPv4 packet's received
IP ToS byte ONLY IF the user has also congured
'qos type-of-service diff-services'
'no qos dscp-map <codepoint>' will remove the settings for the
specied codepoint from the running conguration. 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
congured 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 congured as
follows:
