Known Affected Releases


Description (partial)

A wireless client receiving multicast traffic will experience small gaps during the transmission 
They can recover 
The apparent reason from the information collected is WLC fails to renew the client's entry on the MGID table. Therefore it stops forwarding traffic to the client for a small period of time 2-3 seconds.

>> we have only been able to reproduce this when connecting > 7 clients to an AP and all of them are video streaming 
>> Lower load on the AP does not show the problem
