View multicast groups in AWS Transit Gateway

You can view information about your multicast groups to verify that members were discovered using the IGMPv2 protocol. Member type (in the console), or MemberType (in the AWS CLI) displays IGMP when AWS discovered members with the protocol.

To view multicast groups using the console

  1. Open the Amazon VPC console at https://eusc-de-east-1.console.amazonaws-eusc.eu/vpc/.

  2. On the navigation pane, choose Transit Gateway Multicast.

  3. Select the multicast domain.

  4. Choose the Groups tab.

To view multicast groups using the AWS CLI

Use the search-transit-gateway-multicast-groups command.

The following example shows that the IGMP protocol discovered multicast group members.

aws ec2 search-transit-gateway-multicast-groups --transit-gateway-multicast-domain tgw-mcast-domain-000fb24d04EXAMPLE
