GVRP implemented with LACP for the V5848G has the following issue, so you should
keep in mind that, before configuring GVRP with LACP.
•
If you try to add a port to the member ports of LACP after it is already enabled by
GVRP, all dynamic VLAN information of GVRP port are deleted.
•
GARP Multicast Registration Protocol (GMRP)
By deploying GMRP in a network, it prevents the multicast flooding similar to IGMP
snooping.
If the switch is enabled by GMRP and receives IGMP join message from a host that
wants to join a multicast group, the switch sends the GMRP join message to all other
hosts in the VLAN. And the switch receives the multicast traffic from the source and
forwards it only to the port from which it received join messages for the group.
