The Command Line Interface 403
Air Cleaner
The air cleaner feature offers a number of predetermined filter rules that eliminate
a great deal of unnecessary wireless traffic, resulting in improved performance.
You may select all of the air cleaner rules for the greatest effect, or only specific
rules, such as broadcast or multicast, to eliminate only a particular source of
traffic. The following options are offered:
MyArray(config)# filter add air-cleaner
all All air cleaner filters
arp Eliminate station to station ARPs over the air
broadcast Eliminate broadcast traffic from the air
dhcp Eliminate stations serving DHCP addresses from the air
multicast Eliminate chatty multicast traffic from the air
netbios Eliminate NetBIOS traffic from the air
If you select all, the rules shown in Figure 188 are added to the predefined filter
list named Global. These rules assume that you have station-to-station blocking
enabled, that a DHCP server is on the Array’s wired connection, and that you
want to block most all multicast and all broadcast traffic not vital to normal
