GARP and GVRP Support

The switch supports the Generic Attribute Registration Protocol (GARP).
GARP VLAN Registration Protocol (GVRP) relies on the services provided by
GARP to provide IEEE 802.1Q-compliant VLAN pruning and dynamic
VLAN creation on 802.1Q trunk ports. When GVRP is enabled, the switch
registers and propagates VLAN membership on all ports that are part of the
active spanning tree protocol topology.
For information about configuring GARP timers see "Configuring L2
Multicast Features" on page 803.

Voice VLAN

The Voice VLAN feature enables switch ports to carry voice traffic with
defined priority. The priority level enables the separation of voice and data
traffic coming onto the port. Voice VLAN is the preferred solution for
enterprises wishing to deploy voice services in their network.

Guest VLAN

The Guest VLAN feature allows a switch to provide a distinguished service to
unauthenticated users. This feature provides a mechanism to allow visitors
and contractors to have network access to reach external network with no
ability to browse information on the internal LAN.
For information about configuring the Guest VLAN see "Configuring Port
and System Security" on page 503.

Double VLANs

The Double VLAN feature (IEEE 802.1QinQ) allows the use of a second tag
on network traffic. The additional tag helps differentiate between customers
in the Metropolitan Area Networks (MAN) while preserving individual
customer's VLAN identification when they enter their own 802.1Q domain.
