- Re-maps a given inbound
Differentiated Services codepoint to the specified DSCP Policy and
codepoint on outbound.
Next Available Options:
■
-- 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)
■
-- 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>

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:
