Use the
policy-map
command to specify the name of the policy map to be created, added to, or
modified before you can configure policies for classes whose match criteria are defined in a class
map. Invoking the
policy-map
command enables QoS Policy‐Map configuration mode in which
you can configure or modify the class policies for that policy map.
You can configure class policies in a policy map only if the classes have match criteria defined for
them. You use the
class-map
and
match
commands to configure the match criteria for a class.
You can configure up to 64 class policies in a policy map.
A single policy map can be attached to multiple interfaces concurrently. If you attempt to attach a
policy map to an interface and available bandwidth on the interface cannot accommodate the total
bandwidth requested by class policies comprising the policy map, the interface becomes
oversubscribed. In such a case, when classes try to send with all of their bandwidth, some classes
may be unable to transmit.
Whenever you modify class policy in an attached policy map, CBWFQ is notified and the new
classes are installed as part of the policy map in the CBWFQ system.
