IP multicast forwarding issue on cbs250

[Translator]

Hello!

I am currently purchasing and using the cbs250 model, and I would like to use the cbs250 model to perform ip multicast between peer.

A node and B node performing Multicast exist, A's ip is 10.10.11.21, b's ip is 10.10.11.31.

To do this, we have enable the multicast snooping function of the switch and set all ports to static forwarding.

The igmp-enabled version of the switch was set to v2, and IP multicast was set instead of MAC multicast.

The management ip of the switch was also set to 10.10.11.254.

The multicast table on the switch is confirmed to be normally generated, but the multicast packet sent from the A node does not reach the B node.

There is a big difference between the number of multicast packets sent by the A node and the number of multicast packets received by the B node.

Is there a way to check how to review this problem?

Hello,

Why do you configure static multicast forwarding to all ports? Are you trying to work around an issue with IGMP join or querier not functioning?

Thanks for your feedback.

Hello~

I haven't set up the equipment either, but looking at what you said, it seems that you set it up sequentially well~
However, I'd like to tell you some things to check for reference.

- Multicast > Go to Properties. Verify enable is enabled on Bridge Multicast Filtering Status, verify vlan id is enabled
  Then, check if IP Group Address is set in Forwarding Method for IPv4

- Go to Multicast > IP Multicast Group Address and make sure IP Multicast Group Address is correct

- Multicast > IPv4 Multicast Configuration> Go to IGMP Snooping, make sure that the vlan is snooping enable, and if there is no mrouter, IGMP Querier Status must be enable

- Go to Multicast > IGMP/MLD Snooping IP Multicast Group and make sure it's set up well.
