7.5 GMRP
The switches support IEEE 802.1D-1998 GMRP (GARP Multicast Registration
Protocol), which is different from IGMP (Internet Group Management Protocol).
GMRP is a MAC-based multicast management protocol, whereas IGMP is IP-
based. GMRP provides a mechanism that allows bridges and end stations to
register or de-register Group membership information dynamically. GMRP
functions similarly to GVRP, except that GMRP registers multicast addresses
on ports. When a port receives a GMRP-join message, it will register the
multicast address to its database if the multicast address is not registered, and
all the multicast packets with that multicast address are able to be forwarded
from this port. When a port receives a GMRP-leave message, it will de-
register the multicast address from its database, and all the multicast packets
with this multicast address will not be able to be forwarded from this port.
