Multicast FAST LEAVE causes CPU RISING THRESHOLD
Region : CzechRepublic
Model : TL-SG3210
Hardware Version : V2
Firmware Version : 1.9.8 Build 20140818 Rel.66877(s)
ISP :
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.
What causes this problem? Is this important?
