IPTV over multicast breaks when roaming between APs
we have a specific configuration issue with the ZoneDirector 1100 and ZoneFlex 7372 APs.
When watching a IPTV multicast stream over Wifi, and then roaming between access points, the stream breaks. Without any configuration at all, the IPTV over multicast (VLC player)
worked almost flawlessly, when staying on the same AP, but as soon as my
computer switched to other AP, the stream broke up, failed to recover,
and eventually the SAP list of channels also disappeared until VLC was
Only once it happened that the stream was able to recover after the roaming (after like 4 seconds), and I suspect it was because it has reconnected to the AP it has disconnected from a while before.
This happens on all the computers we've tried. The encryption type (802.1x EAP vs WPA2 pre-shared key) does not matter, it happens on both.
As it is, we have our APs connected to multiple Cisco Catalyst 2960 switches, with IGMP snooping enabled on each of them. Each Catalyst is connected (either directly or indirectly) to our core switch, and several of the APs are also on the core. Also the ZoneDirector has IGMP snooping enabled and directed multicast is also enabled. Disabling directed multicast did not help.
We use ZoneDirector 1100 and APs are ZoneFlex 7372.
Does anyone have a clue what we could be missing here? Does Ruckus support handing over multicast group membership?
Thank you in advance!
