To configure a policy map, perform this task:
Command
Step 1
switch# configure terminal
Step 2
switch(config)# policy-map name
Step 3
switch(config-pmap)# class class-name
Step 4
switch(config-pmap-c)# pause no-drop
Step 5
switch(config-pmap-c)# mtu value
Step 6
switch(config-pmap-c) bandwidth percent
percentage
Step 7
switch(config-pmap-c) priority
Step 8
switch(config-pmap-c) multicast-optimize
The switch distributes all the policy map configuration values to the attached network adapters.
Note
Policy maps can also be configured for interface service policies. However, different parameters are
Note
supported in these policy maps. See the
The following example shows how to enable optimized multicast for the default Ethernet class:
switch(config)# policy-map s1
switch(config-pmap)# class class-default
switch(config-pmap-c)# multicast-optimize
The following example shows how to create a policy map with a no-drop Ethernet class:
switch(config)# class-map ethCoS4
switch(config-cmap)# match cos 4
switch(config-cmap)# exit
switch(config)# policy-map ethNoDrop
switch(config-pmap)# class ethCoS4
switch(config-pmap-c)# pause no-drop

Purpose
Enters configuration mode.
Creates a named object representing a set of policies
that are to be applied to a set of traffic classes.
Policy-map names can contain alphabetic, hyphen, or
underscore characters, are case sensitive, and can be up
to 40 characters.
Associates a class map with the policy map, and enters
configuration mode for the specified system class.
(Optional) Configures a no-drop class. If you do not
specify this subcommand, the default policy is drop.
The operation for drop policy is simple tail
Note
drop, where arriving packets will be dropped if
the queue increases to its allocated size
(Optional) Specifies the MTU value in bytes.
(Optional) Specifies the guaranteed percentage of
interface bandwidth allocated to this class.
(Optional) Specifies that traffic in this class is mapped
to a strict priority queue.
(Optional) Enables multicast optimization. Multicast
traffic in this class will be served by all available
multicast queues.
Only one class in a policy map can be
Note
configured for multicast optimization.
