Wireless Array
Configuring the Wireless Array 289
exceeded, so entering unlimited, in practice, will stop at the per-IAP
limit. If you have an unlicensed Array, this value is set to 1, which simply
allows you to test the ability to connect to the Array.
16. Max Station Association per IAP: This defines how many station
associations are allowed per IAP. The maximum is 240 (up to 120 on the
XR-500 Series). Note that the SSIDs > SSID Management window also has
a station limit option — Station Limit, and the windows for Global
Settings .11an and Global Settings .11bgn also have Max Stations settings.
If multiple station limits are set, all will be enforced. As soon as any limit
is reached, no new stations can associate until some other station has
terminated its association.
17. Block Inter-Station Traffic: This option allows you to block or allow
traffic between wireless clients that are associated to the Array. Choose
either Yes (to block traffic) or No (to allow traffic).
18. Allow Over Air Management: Choose Yes to enable management of the
Array via the IAPs, or choose No (recommended) to disable this feature.

19. Multicast Processing: This sets how multicast traffic is handled.
Multicast traffic can be received by a number of subscribing stations at
the same time, thus saving a great deal of bandwidth. In some of the
options below, the Array uses IGMP snooping to determine the stations
that are subscribed to the multicast traffic. IGMP (Internet Group
Management Protocol) is used to establish and manage the membership
of multicast groups.
Multicast handling options are only applicable to traffic transmitted from
the Array to wireless stations. Select one of the following options:
• Send multicasts unmodified. This is useful when multicast is not
needed because no video or audio streaming is required or when it is
used only for discovering services in the network. Some situations
where you might use this option are:
