How To Configure Hardware Filters on AT-9900, x900-48, and x900-24 Series Switches

Introduction

The AT-9900, x900-48, and x900-24 series switches support a powerful hardware based packet-filtering facility.

These switches can filter on a range of Layer 2, Layer 3, and Layer 4 packet attributes, and perform a variety of different actions on the packets that match the filters.

Because the filters are hardware-based, they put no load on the CPU of the switch, and have no affect on the throughput of the switch. It is possible to configure over 1000 different filters, and still have complete wire speed throughput on the switch.

The following configuration methods are available:

1.To filter traffic across all ports on the switch, create dedicated hardware filters.

2.To filter traffic on a per-port basis, apply filtering actions to QoS flow groups or traffic classes.

This Note only describes method 1. Method 2 is described in How To Configure Filtering Actions on QoS Flow Groups and Traffic Classes, available from www.alliedtelesis.com/resources/ literature/howto.aspx.
