Step 1: Create a Policy Map
A policy map can be created in the same way as a class map. Using the policy-map command,
a policy map is created with a unique name. To disable the command, use the no form of this
command:
policy-map class-map_name
Like a class map, the execution of a policy-map command will place you in the policy map
configuration mode. The policy map configuration mode supports two commands:
■ description {description}—Specifies a description for the policy-map command.
■ class {class-map name}—Specifies the class map that will be associated with the policy
map. You can associate multiple class maps with a single policy map.
Step 2: Assign Traffic Classes to the Policy Map
With the policy map created, traffic classes must be assigned to the policy map. To do this,
use the class command while in the policy map configuration mode. This will access the class
configuration mode for that specific class map assigned to the policy map, as illustrated in
Example 8-3.
Each class map added to the policy map will have its own class configuration mode. All
actions assigned in these modes will only affect traffic matched using that specific class map.
Step 3: Assign Policies for Each Class
You can assign five policies, or domains, to traffic classes within a policy map. The five
policies are as follows:
■ police—Allows rate limiting of matched traffic flows.
■ inspect—Allows protocol inspection services on the matched traffic flows.
NOTE Like class maps, there is a default policy map called global_policy. This is a policy
map that cannot be removed or turned off and is defaulted to protocol inspection.
