Full 802.1Q VLAN Tagging Compliance
IEEE 802.1Q defines an architecture for virtual, bridged LANs, the services
provided in VLANs, and the protocols and algorithms involved in the
provision of these services.

GVRP Support
GARP VLAN Registration Protocol
(GVRP) provides IEEE 802.1Q-
compliant VLAN pruning and dynamic VLAN creation on 802.1Q trunk
ports. When GVRP is enabled, the device registers and propagates VLAN
membership on all ports that are part of the active underlying Spanning Tree
Protocol topology.

Voice VLAN
Voice VLAN enables network administrators to enhance VoIP service by
configuring ports to carry IP voice traffic from IP phones on a specific VLAN.
VoIP traffic has a preconfigured Organizationally Unique Identifiers (OUI)
prefix in the source MAC address. Network administrators can configure
VLANs from which voice IP traffic is forwarded. Non-VoIP traffic is dropped
from the Voice VLAN in Auto-Voice VLAN Secure mode. Voice VLAN also
provides QoS to VoIP, ensuring that the quality of voice does not deteriorate if
the IP traffic is received unevenly.
The default secure mode is
supported

Guest VLAN
Guest VLAN provides limited network access to unauthorized ports. If a port
is denied network access via port-based authorization, but the Guest VLAN is
enabled, the port receives limited network access through the Guest VLAN.
