PACKET FILTERS

This chapter provides guidelines and other key information about how to administer bridge packet filters in your system, including the following tasks:

■Listing and displaying packet filters

■Creating, deleting, editing, and loading packet filters

■Assigning and unassigning packet filters

■Managing port groups

Independently configurable packet filtering is provided for the packet processing paths on each bridge port of the system. After you create a packet filter, you can assign the filter to the transmit or the receive paths of any bridge port or group of bridge ports.

The filter executes a series of test operations on the packet’s contents and, if the result is zero, it stops (filters) the packet. If the end result is non-zero, the filter lets the packet pass.

For more information about implementing packet filters on your network, see the Implementation Guide for your system.

For the CoreBuilder® 9000 platform, the commands in this chapter apply to Layer 3 switching modules only.
