EX-4300MP Multicast through Virtual Chassis

2 weeks ago

Greetings everyone,

 

I am experiencing an issue on EX-4300MP series switches. When I configure them in virtual chassis and enable IGMP snooping, it does not seem to pass multicast traffic through the VC. I have a pretty basic config loaded on this with only:

 

igmp-snooping {
     vlan default {
          query-interval 30;
          l2-querier {
               source-address <ip of switch>;
          }
     }
}

 

Tried on different firmware:

18.4R2-S3

19.4R2-S1

 

Is anyone else experiencing this behaviour? Did I miss some multicast configuration necessary for VC?

 

Help would be greatly appreciated.

 

Thanks,

ME

Hi Mario,

 

Could you please provide a simple logic diagram of the multicast traffic flow including intermediate devices, source and multicast clients.

 

Also the following outputs:

> show igmp-snooping membership detail
> show igmp-snooping membership vlan <vlan name> detail

> show igmp snooping interface
> show igmp-snooping statistics

 

My advise is to open a JTAC Service Request as multicast issues usually requires investigation, testing and troubleshooting sessions to get it working.

Is it an access or distribution switch?

Maybe you need to analyze where to apply igmp snooping
