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-GS950/16PS 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-
GS950/16PS switch.
