Policies and Filters

Syntax
Use the following CLI commands or Web management interface panels to configure cache server redirection
policies.
Foundry Filters
A filter is a set of comparison values and an action. If a packet matches the set of values in the filter, the Foundry
device takes the action specified in the filter. Foundry devices provide filters for Layer 2, Layer 3, and Layer 4.
A filter looks at the appropriate fields in a packet to compare information related to one of the layers. For example,
MAC filters look at the source and destination MAC address and, optionally, at the encapsulation information. IPX
filters look at the source and destination network and socket information but do not look at the MAC information.
The following table lists the various types of filters you can configure on Foundry devices.
