Configuring QoS
You can also enter the match criteria as match vlan 100 200 300 with the same result.

Each per-port, per-VLAN parent policy class, except class-default, can have a child policy association.

Table Maps
You can use table maps to manage a large number of traffic flows with a single command. You can
specify table maps in set commands and use them as mark-down mapping for the policers. You can also
use table maps to map an incoming QoS marking to a replacement marking without having to configure
a large number of explicit matches and sets. Table maps are used only in input policy maps.
Table maps can be used to:
•
•
•
A table map includes one of these default actions:

"Configuring Per-Port Per-VLAN QoS with Hierarchical Input Policy Maps" section on
for configuration information, including configuration guidelines and limitations.
Correlate specific CoS, DSCP, or IP precedence values to specific CoS, DSCP, or IP precedence
values
Mark down a CoS, DSCP, or IP precedence value
Assign defaults for unmapped values
default default-value—applies a specific default value (0 to 63) for all unmapped values
default copy—maps all unmapped values to the equivalent value in another qualifier
default ignore—makes no changes for unmapped values
