DCM Gbe input port is not joining Multicast stream

DCM will not join a multicast stream if the Gbe port is disabled while configuring IGMP for that port. Also when the DCM was joined but the Gbe port has been disabled for a longer time afterwards, it is necessary to reconfigure IGMP when the port is enabled. This to force the DCM again to join the multicast stream Solution : • Make sure the Gbe port is enabled • Remove and re-apply the IGMP configuration again to force the DCM to join the multicast again.
