ILTERS
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.
