Configuring a Policy
The Policy Table Map page displays the list of advanced QoS polices defined in
the system. The page also allows you to create and delete polices. Only those
policies that are bound to an interface are active (see Policy Binding page).
Each policy consists of:
• One or more class maps of ACLs which define the traffic flows in the policy.
• One or more aggregates that applies the QoS to the traffic flows in the
policy.
After a policy has been added, class maps can be added by using the Policy Table
page.
To add a QoS policy:
STEP 1 Click Quality of Service > QoS Advanced Mode > Policy Table.
This page displays the list of defined policies.
STEP 2 Click Policy Class Map Table to display the Policy Class Maps page.
-or
Click Add to open the Add Policy Table page.
STEP 3 Enter the name of the new policy in the New Policy Name field.
