Port-Based VLANs

Port-based VLANs classify incoming packets to VLANs based on their ingress
port. When a port uses 802.1X port authentication, packets can be assigned
to a VLAN based on the result of the 802.1X authentication a client uses
when it accesses the switch. This feature is useful for assigning traffic to
Guest VLANs or Voice VLANs.

IP Subnet-based VLAN

This feature allows incoming untagged packets to be assigned to a VLAN and
traffic class based on the source IP address of the packet.

MAC-based VLAN

This feature allows incoming untagged packets to be assigned to a VLAN and
traffic class based on the source MAC address of the packet.

IEEE 802.1v Protocol-Based VLANs

VLAN classification rules are defined on data-link layer (Layer 2) protocol
identification. Protocol-based VLANs are used for isolating Layer 2 traffic for
differing Layer 3 protocols.

GARP and GVRP Support

The switch supports the configuration of Generic Attribute Registration
Protocol (GARP) timers 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 703.

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. The Voice VLAN
feature is not available only on the M6348 switch.
