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 Amazon CLI) displays IGMP when Amazon discovered members with the
protocol.

-
Open the Amazon VPC console at https://console.amazonaws.cn/vpc/
. -
On the navigation pane, choose Transit Gateway Multicast.
-
Select the multicast domain.

Choose the Groups tab.
To view multicast groups using the Amazon CLI
