Protocol-Based Groups to VLAN Mapping

To map a protocol group to a port, the port must be in General mode and not have
DVA configured on it (see Configuring VLAN Interface Settings).
Several groups can be bound to a single port, with each port being associated to
its own VLAN.
It is possible to map several groups to a single VLAN as well.
To map the protocol port to a VLAN:
STEP 1 Click VLAN Management > VLAN Groups > Protocol-Based Groups to VLAN.
The currently-defined mappings are displayed.
STEP 2 To associate an interface with a protocol-based group and VLAN, click Add.
STEP 3 Enter the following fields.
Interface—Port or LAG number assigned to VLAN according to protocol-
based group.
Group ID—Protocol group ID.
VLAN ID—Attaches the interface to a user-defined VLAN ID.
STEP 4 Click Apply. The protocol ports are mapped to VLANs, and written to the Running
Configuration file.
Voice VLAN
In a LAN, voice devices, such as IP phones, VoIP endpoints, and voice systems are
placed into the same VLAN. This VLAN is referred as the voice VLAN. If the
voice devices are in different voice VLANs, IP (Layer 3) routers are needed to
provide communication.
