GS1920-24HP with LACP and a lot of Multicast storm hits

GiuseppeR

Hello everyone,

as per default when I have more LAN cables from a rack to another one I am used to setup a LACP connection.

So in my latest setup i linked together 4 ports:

Anyway this is the first time I see a lot of multicast storm hits on this LACP aggregation:

This is the only LACP link that I have on my ORGs that has this problem.

Have I to setup a storm control?

Is there a tool inside Nebula to inspect which is the origin of that storm?

Hi @GiuseppeR,

Based on the pictures you provided, it appears that there is currently no multicast storm issue occurring. Therefore, we recommend not setting up storm control at this time.

Regarding your question about whether there is a tool in Nebula to identify the origin of the storm, Nebula does not have a specific tool for this purpose. However, please refer to this FAQ to investigate the origin of the storm, which explains how to capture packets to find the source of the storm.
