Configuring Modular Quality of Service Packet Classification on Cisco ASR 9000 Series Routers
Command or Action
Step 6
match [not] discard-class discard-class-value
[ discard-class-value1 ... discard-class-value6 ]
Example:
RP/0/RSP0/CPU0:router(config-cmap)# match
discard-class 5
Step 7
match [not] dscp [ipv4 | ipv6] dscp-value
[ dscp-value ... dscp-value ]
Example:
RP/0/RSP0/CPU0:router(config-cmap)# match dscp
ipv4 15
Step 8
match [not] mpls experimental topmost exp-value
[ exp-value1 ... exp-value7 ]
Example:
RP/0/RSP0/CPU0:router(config-cmap)# match mpls
experimental topmost 3
Step 9
match [not] precedence [ipv4 | ipv6]
precedence-value [ precedence-value1 ...
precedence-value6 ]
Example:
RP/0/RSP0/CPU0:router(config-cmap)# match
precedence ipv4 5
Step 10
match [not] protocol protocol-value
[ protocol-value1 ... protocol-value7 ]
Example:
RP/0/RSP0/CPU0:router(config-cmap)# match
protocol igmp
Step 11
match [not] qos-group [ qos-group-value1 ...
qos-group-value8 ]
Example:
RP/0/RSP0/CPU0:router(config-cmap)# match
qos-group 1 2 3 4 5 6 7 8
Step 12
match source-address mac source-mac-address
Example:
RP/0/RSP0/CPU0:router(config-cmap)# match
source-address mac 00.00.00

Cisco ASR 9000 Series Aggregation Services Router Modular Quality of Service Configuration Guide
Purpose
(Optional) Specifies a discard-class-value in a class map to
match packets.
• The discard-class-value argument is specified as an
integer from 0 to 7.
The match discard-class command is supported only for an
egress policy.
(Optional) Identifies a specific DSCP value as a match
criterion.
The value range is from 0 to 63.
•
Reserved keywords can be specified instead of numeric
•
values.
Up to eight values or ranges con be used per match
•
statement.
(Optional) Configure a class map so that the three-bit
experimental field in the topmost Multiprotocol Label
Switching (MPLS) labels are examined for experimental
(EXP) field values.
The value range is from 0 to 7.
(Optional) Identifies IP precedence values as match criteria.
The value range is from 0 to 7.
•
Reserved keywords can be specified instead of numeric
•
values.
(Optional) Configures the match criteria for a class map on
the basis of the specified protocol.
(Optional) Specifies service (QoS) group values in a class
map to match packets.
A QoS group value identifier argument is specified as
•
the exact value or range of values from 0 to 63.
Up to eight values (separated by spaces) can be entered
•
in one match statement.
The match qos-group command is supported only for
•
an egress policy.
(Optional) Configures the match criteria for a class map
based on the specified source MAC address.
