23. MDNS Filter: There are many different types of services that may be
specified in multicast query and response packets. The mDNS filters let
you restrict forwarding, so that multicast packets are forwarded only for
the services that you explicitly specify. This list may be used to restrict the
amount of Apple Bonjour multicast traffic forwarding. For example, you
may restrict forwarding to just AppleTV and printing services. Please see
the description of multicast forwarding in Step 21 above.
The MDNS Filter operates as follows:
• If you leave this field blank, then there is no filter, and mDNS
packets for all service types are passed.
• If you enter service types, then this acts as an allow filter, and
mDNS packets are passed only for the listed service types.
To add an mDNS packet type to the list of packets that may be forwarded,
select it from the drop-down list in the top field and click the Add button
to its right. The drop-down list offers packet types such as AirTunes,
Apple-TV, iChat, iPhoto, iTunes, iTunes-Home-Sharing, Internet-
Printing, Mobile-Device-Sync, and Secure-Telnet.
For example, to allow mirroring of an iPad on an Apple-TV, select Apple-
TV.
You may define your own type if you do not see the service you want in
the drop-down list. Simply enter the mDNS service name that you would
like to allow through. Custom mDNS packet types must be prefixed with
an underscore, e.g., _airvideoserver.
To remove an entry, select it in the list and click Delete. To remove all
entries from the list, click Reset.
24. Broadcast Rates: This changes the rates of broadcast traffic sent by the
Array (including beacons). When set to Optimized, each broadcast or
multicast packet that is transmitted on each radio is sent at the lowest
transmit rate used by any client associated to that radio at that time. This
results in each IAP broadcasting at the highest Array TX data rate that can
be heard by all associated stations, improving system performance. The
rate is determined dynamically to ensure the best broadcast/multicast
