How to Define Filters in the QoS Policy

Before You Begin

Before you can perform the next steps, you should have completed the procedure How to Define the Classes for Your QoS Policy.

1. Create at least one filter for each class in the QoS planning table that you created in How to Define the Classes for Your QoS Policy.

   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 that was introduced in Table 33–1 to fill in filters for the classes you defined.

The next table is an example that shows how you would define a filter for outgoing FTP traffic.
