Configuration
menu. The following screen appears:
Figure 6-40. GVRP Configuration screen
This screen allows you to enable or disable GARP VLAN Registration Protocol (GVRP), where GARP is the
Generic Attribute Registration Protocol, on individual ports. GVRP updates dynamic VLAN registration
entries and communicates the new VLAN information across the network. This allows, among other things,
for stations to physically move to other switch ports and keep their same VLAN settings, without having to
reconfigure VLAN settings on the Switch. Press APPLY to let your changes take effect.
Configure GMRP
Group Multicast Registration Protocol (GMRP) allows multicasts to be sent on a single VLAN without
affecting other VLANs or broadcast domains. Group registration entries indicate for each port whether frames
to be sent to a group MAC address and on a certain VLAN should be filtered or discarded. Use the
GMRP
Configuration
screen to enable or disable GMRP.
To make GMRP configuration changes, select
Configure GMRP
at the bottom of the
VLAN Configuration
menu (when
IEEE 802.1Q VLANs
is set). The following screen appears:
