TitleMulticast Streams Getting Dropped on ExtremeSwitching 200 Series
Symptoms
  • High CPU usage
  • Multicast behavior issues (flashing, no video)
Environment
  • ExtremeSwitching 200 Series
  • 01.02.01.0005
  • Multicast Video Streams
Cause
Due to a software bug, the switch is missing IGMP reports and unsubscribed video streams are going to the CPU of the switch.
Resolution
If the switch is the IGMP querier, set the igmp query interval to '2' using the following command
 
set igmp querier query-interval 2
And set the timeout value to 300 seconds via the following command, options 60-300
 
set igmp querier timer expiry 300

Additionally, there's also a patch coming to resolve the issue, but it hasn't been released yet.
