General Guidelines

Here is a summary of the rules to observe when you create a voice VLAN:
One voice VLAN can be configured on the switch at any time.

A voice VLAN is based on a pre-defined tagged VLAN.

The voice VLAN Auto-Detection feature can only be enabled on

ports that are initially defined as non-members of the tagged
VLAN.
On ports that are configured for the voice VLAN Auto-Detection

feature, each IP phone must be manually configured per the
manufacturer's instructions for the VLAN ID that matches your
AT-GS950/24 voice VLAN ID.
Member ports of a tagged VLAN are static and cannot have the

voice VLAN Auto-Detection feature enabled.
IP phones that are not VLAN aware should be connected to Static

tagged ports of the voice VLAN.
The voice VLAN uplink/downlink port(s) must be configured as

Static tagged or tagged ports.
Any Static tagged members of the voice VLAN are required to have

the port VLAN ID (PVID) configured to be the same as the voice
VLAN ID.
The Organization Unique Identifier (OUI) is configured by entering

an IP phone's MAC address into the configuration.
Only one MAC address representing each unique OUI can be

configured at one time.
Up to 10 IP phone MAC addresses/OUIs can be configured at one

time.
Link Layer Discovery Protocol for Media Endpoint Devices (LLDP-

MED) is not supported on the AT-GS950/24 switch.
Power over Ethernet (PoE) is not supported on the AT-GS950/24

switch.
