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
1
000 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
