Step 7

Step 8

The following example shows that the system class best-effort-drop-class is guaranteed 20 percent of the
bandwidth on interface ethernet 1/1:
switch(config)# class-map best-effort-drop-class
switch(config-cmap)# match cos 5
switch(config)# policy-map policy1
switch(config-pmap)# class best-effort-drop-class
switch(config-pmap-c)# bandwidth percent 20
switch(config)# interface ethernet 1/1
switch(config-if)# service-policy input policy1
Configuring Egress Policies
An egress policy is a service policy applied to the outgoing traffic on an Ethernet interface. You can
configure an egress policy to guarantee the bandwidth for the specified traffic class or to configure the
egress queues.
To configure an egress policy, perform this task:
Command
Step 1
switch# configure terminal
Step 2
switch(config)# class-map class-name
Step 3
switch(config)# policy-map policy-name
Step 4
switch(config-pmap)# class class-name
Step 5
switch(config-pmap-c) bandwidth percent
percentage
Step 6
switch(config-pmap-c) priority

Purpose
(Optional) Specifies the guaranteed percentage of
bandwidth allocated to incoming traffic of this class.
(Optional) Specifies that ingress traffic in this class is
mapped to a strict priority queue.
Enters configuration mode for the specified interface.
The service policy on a port channel overrides
Note
any service policy configuration on individual
member interfaces.
Applies the policy map to the interface.
Purpose
Enters configuration mode.
Defines a class name for the egress policy.
Creates a policy map to specify the QoS parameters
for the egress policy.
Associates the egress class with this policy and enters
configuration mode for the class.
Specifies the guaranteed percentage of bandwidth
allocated to this class.
Specifies that egress traffic in this class is mapped to
a strict priority queue.
