Configuration Examples for Configuring Percent-Based Policing
This section provides the following configuration examples:
• Configuration Example for Configuring Percent-Based Policing, page 6-32
• Configuration Example for Configuring Percent-Based Two-Color Policing, page 6-33
• Configuration Example for Configuring Percent-Based Three-Color Policing, page 6-33
• Configuration Example for Configuring Percent-Based Policing in a Hierarchical Policy, page 6-34
• Configuration Example for Percent-Based Policing of a Priority Service, page 6-34
Configuration Example for Configuring Percent-Based Policing
Example 6-9 shows how to configure percent-based policing. In the example, the class named Premium
is configured in the policy map named Test. The Premium class is a priority class with a queue depth of
32. The router allocates 5 percent of the committed rate to Premium traffic and allows burst sizes of 2
ms
for both committed and excess bursts.
Example 6-9 Configuration Example for Percent-Based Policing
Router(config)# policy-map Test
Router(config-pmap)# class Premium
Router(config-pmap-c)# priority
Router(config-pmap-c)# queue-limit 32
Router(config-pmap-c)# police percent 5 2 ms 2 ms
