If the endpoints support IGMP, ensure there is a querier in the VLAN
For EXOS to work as an IGMP querier, there must be an IP address on the VLAN. Configure an IP address on at least one switch in the Dante network.
configure vlan <vlan_name> ipaddress <ip_address>/<netmask>
If the endpoints do not support IGMP, either disable IGMP snooping or create static joins for the endpoints.
