classification disable
command. By default, IEEE 802.1p is disabled.
After creating class-maps, system checks the inbound or outbound packets by the criteria in
class-maps. QoS actions defined in the policy-map for the class will be applied to the classified
packets into classes.
You can create a class-map by using the
class-map
command in QoS configuration mode.
When you enter the
class-map
command, the Corecess R1-SW24L2B enters the class-map
configuration mode. In this mode, the match criterion is defined for the traffic by using the
match
command.
To create a class-map and add the criteria to the class-map, use the following command in the
Privileged mode:
To create a class map and specify the way in which the Corecess R1-SW24L2B should classify
traffic, enter the following commands in Global configuration mode:

2. (Optional) Enables IEEE 802.1p. If IEEE 802.1p
is enabled, CoS field is available for the criterion
of the class-map. If IEEE 802.1p is disabled
(default setting), IP precedence and DSCP fields
become available instead of CoS field.
