As a
Multicast capable Switch
we recommend is the HP (ARUVA) 2530 24G or 48G.
(For Floor switches we have an own branded one and support IGMP as well) IGMP should be set to
ON in the port configs. The latest HP Firmware might not be the best choice. Better to test IGMP
functions before installation into a HOT running System and eventually do a downgrade of the
Firmware. This one works:
General notes about Streams:

Multicast Address Ranges:
We recommend, that the addressing of your Multicast streams should be in conjunction with this listings to
avoid conflicts with other network equipment or protocols.

Note
Host Extensions for IP Multicasting [ RFC1112 ] specifies the extensions required of a host
implementation of the Internet Protocol (IP) to support multicasting. The multicast
addresses are in the range 224.0.0.0 through 239.255.255.255. Address assignments are
listed below.
The range of addresses between 224.0.0.0 and 224.0.0.255, inclusive, is reserved for the
use of routing protocols and other low-level topology discovery or maintenance protocols,
such as gateway discovery and group membership reporting. Multicast routers should
not forward any multicast datagram with destination addresses in this range, regardless of
its TTL.
