VLAN Membership
VLAN implementation allows:
VLANs across multiple switches by using explicit or implicit tagging and the GARP/GVRP protocol defined in IEEE802.1p and 802.1Q.
An end station’s network interface card may belong to multiple VLANs.
A switch port may be associated with multiple VLANs.
Definitions of VLAN Membership
VLAN implementation allows VLAN membership to be defined based on ports. Port- based VLANs are organized by physical port number. For example, switch ports 1, 2, 4 and 6 can be grouped on VLAN, while server ports 3, 5, 7 and 8 can be on another VLAN. Broadcasts from servers within each group would only go to the members of its own VLAN. This ensures that broadcast storms cannot cause a network meltdown due to traffic volume.
VLAN Membership Learning
Remote VLAN Learning
In addition to providing network management tools that allow network administrators to statically add and delete VLAN member ports, the switch also supports GVRP (GARP VLAN Registration Protocol). GVRP allows for dynamic registration of VLAN port members within switch and across multiple switches.
Other than supporting dynamic updating of registration entries in a switch, GVRP is used to communicate VLAN registration information to other
GVRP allows both
