Configuring QoS on Interfaces
QoS parameters that can be configured on Ethernet and port channel interfaces are described in the
following topics:
• Configuring Ingress Policies, page 31-13
• Configuring Egress Policies, page 31-14
Configuring Ingress Policies
An ingress policy is a service policy applied to incoming traffic on an Ethernet interface. The ingress
policy is applied in the adapter to all outgoing traffic that matches the specified class. When you
configure an ingress policy on an interface or port channel, the switch sends the configuration data to
the adapter.
To configure an ingress policy, perform this task:
Command Purpose
Step 1
switch# configure terminal
Enters configuration mode.
Step 2
switch(config)# class-map class-name
Creates a class for the ingress policy.
Step 3
switch(config)# policy-map policy1-name
Creates a policy map to specify the QoS parameters for
the ingress policy.
Step 4
switch(config-pmap)# class class-name
Associates the ingress class with this policy and enters
configuration mode for the class.
