Hi,
I´m using L2 managed switch SG3210 behind PON OLT. Switch is used to distribute internet VLAN and IPTV VLAN to end users. I have setup IGMP snooping for proper VLAN.

I had enabled FAST LEAVE option, but IPTV units still delete and create multicast groups. I do not remember right time intervals, but it was aprox. 5 minutes. Strange is, that this behavior starts after 20-40 hours uptime.

So i tried to disable FAST LEAVE. After doing this, IPTV units keeps their multicast groups and TV transmissions works correctly. But when uptime of switch reach 24+ hours, switch reach CPU RISING THRESHOLD warning in log. Log is shown below.
