the 'no dscp-map <af11..ef|0-63|000000...111111>' function
must be used.

Differentiated Services codepoint to the specied DSCP Policy and
codepoint on outbound.
Next Available Options:
■ ip-precedence -- In IP-Precedence mode, IPv4 packets are classified and given a QoS priority
based on the upper 3 bits of the IP ToS field. The priority association is automatic and cannot
be changed: IP-Precedence 802.1p ToS Bits Priority -------------------------------- 111 7 (Highest) 110
6 101 5 100 4 011 3 010 0 (Normal) 001 2 (Low) 000 1 (Lowest) (p. 424)
■ diff-services -- In IP Differentiated Services (Diffserv) mode, IPv4 packets are classified and
given a QoS priority based on the upper 6 bits of the IP ToS field from the packets as they enter
the switch. The assignment of Diffserv Codepoints to 802.1p priorities is done via the qos
dscp-map command. Any Diffserv Codepoint in an inbound IPv4 packet can be re-mapped to
a different codepoint (and its associated 802.1p priority) on outbound. This is done by using
the syntax: qos type-of-service diff-services <af11..ef|0-63|000000...111111> dscp
<af11..ef|0-63|000000...111111> (p. 418)

Description: Dene 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 classier uses
this DSCP policy as the method of trafc prioritization.
The mapping also provides the prole for inbound classication
and priority assignment based on an IPv4 packet's received
IP ToS byte ONLY IF the user has also congured
'qos type-of-service diff-services'
'no qos dscp-map <codepoint>' will remove the settings for the
specied codepoint from the running conguration. 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
congured 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 congured as
follows:
