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-GS950/48PS 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-
GS950/48PS switch.
