How to Define Filters in the QoS Policy

Before You Begin

Before you can define filters, you need to define the classes for your QoS policy. For more information, see Defining the Classes for Your QoS Policy on page 29.

1. Create at least one filter for each class in your QoS planning table.

   Consider creating separate filters for incoming and outgoing traffic for each class, where applicable. For example, add an ftp-in filter and an ftp-out filter to the QoS policy of an IPQoS-enabled FTP server. You then can define an appropriate direction selector in addition to the basic selectors.

2. Define at least one selector for each filter in a class.

   Use the QoS planning table to track the filters for the classes you defined.

The following example shows how you would define a filter for outgoing FTP traffic.
