Purpose
Associates a class map with the policy map, and enters
configuration mode for the specified system class.
The associated class map must be the same type as the
Note
policy map type.
Configures a no-drop class. If you do not specify this command,
the default policy is drop.
The operation for the drop policy is a simple tail drop,
Note
where arriving packets will be dropped if the queue
increases to its allocated size.
The pfc-cos-value range is from 0 to 7. This option is
supported only for a ACL-based system class (which
filters traffic using criteria other than cos-based
matches).
The list of CoS values can potentially
Caution
include the CoS value that is used for FCoE
traffic in class-fcoe. You must determine if
this is desired behavior for your topology.
Associates a class map with the policy map, and enters
configuration mode for the specified system class.
The associated class map must be the same type as the
Note
policy map type.
Enables the jumbo MTU for the whole switch by setting the
MTU to its maximum size (9216 bytes) in the policy map for
the default system class (class-default).
Purpose
Enters global configuration mode.
