Purpose
Enters global configuration mode.
Enters policy map configuration mode.
Creates or modifies a policy map that can be attached to
•
one or more interfaces to specify a service policy.
Specifies the name of the class whose policy you want to
create or change.
Enters policy map class configuration mode.
Specifies the bandwidth allocated for a class belonging
•
to a policy map.
In this example, class class1 is guaranteed 50 percent of
•
the interface bandwidth.
Specifies how to allocate leftover bandwidth to various
classes.
• The remaining bandwidth of 40 percent is shared by
class class1 and class2 (see Steps 8 and 9) in a 20:80
ratio: class class1 receives 20 percent of the 40 percent,
and class class2 receives 80 percent of the 40 percent.
Returns the router to policy map configuration mode.
Specifies the name of a different class whose policy you
want to create or change.
