filter Clause

Filters are made up of selectors that group traffic flows into classes. These selectors specifically define the criteria to be applied to traffic of the class that was created in the class clause. If a packet matches all selectors of the highest-priority filter, the packet is considered to be a member of the filter's class. For a complete list of selectors that you can use with the ipgpc classifier, refer to Table 37–1.

You define filters in the IPQoS configuration file by using a filter clause, which has the following syntax:

filter { 
       name filter-name
       class class-name 
       parameters (selectors)
       }
