address. The port will leave the voice VLAN after a specified timeout
period. This port behavior is configured with the voice VLAN Auto-
Detection feature.
For the Auto-Detection feature to function, your IP phone(s) must be
capable of generating 802.1Q packets with imbedded VLAN ID tags. You
must manually configure your IP phone(s) for the same VLAN ID as the
switch's voice VLAN ID. When voice data is detected on one of the "Not
Member" ports, the packets from the IP phone will contain the voice VLAN
ID so they are switched within the switch's voice VLAN.
One or more ports in your voice VLAN must be configured as Static tagged
or untagged members. Static VLAN members are permanent member
ports of the voice VLAN and there is no dependency on the configuration
of the devices connected to the ports. These ports might be connected to
other voice VLAN network nodes such as other Ethernet switches, a
telephone switch, or a DHCP server. The voice VLAN Auto-Detection
feature cannot be enabled on Static tagged or tagged ports.
Note: 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. This insures that
all untagged packets entering the port are switched within the voice VLAN as the
voice data passes through the switch.
If the IP phone(s) that you are installing cannot be configured with a VLAN
ID, then the switch ports should be configured as Static tagged ports
within the voice VLAN.
Note: Link Layer Discovery Protocol for Media Endpoint Devices (LLDP- MED) is not
supported on the switch. Each IP phone that is VLAN aware should be manually
configured for the VLAN ID that matches your voice VLAN ID. Each of the voice
VLAN ports connected to an IP phone should be configured as "Not Member" ports
of the tagged VLAN.

Note: Prior to configuring your voice VLAN, you must first configure a
tagged VLAN. This VLAN will be used as a basis for your voice VLAN.
