Multicast and Broadcast Issues?

Zanchie

With the Switch device just working again, it receives Multicast log on the uplink port, while the uplink port has Storm Control enabled.

What does that log show?

Hi @Zanchie,

This log shows that the switch detected a port receiving multicast packets over the multicast limit value. In other words, it means this port received more than 100 pps of multicast packets.

Is there any handling to limit multi -directional packets from IPTV

Hi @Zanchie,

For IPTV, we have ADVANCED IGMP to handle the multicast traffic. Please reference this FAQ to understand ADVANCED IGMP feature.

Setting up your IPTV network with Nebula — Zyxel Community

Hope it helps.

Hi @Zanchie,

The different leave time is because of the different roles, topper layer needs more leave time. In addition, you can adjust the leave time longer than our default value.
