Chapter 20: Voice VLAN
260
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 AT-GS950/16PS 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 AT-GS950/16PS switch. Each
IP phone that is VLAN aware should be manually configured for the
VLAN ID that matches your AT-GS950/16PS voice VLAN ID. Each
of the AT-GS950/16PS voice VLAN ports connected to an IP phone
should be configured as “Not Member” ports of the tagged VLAN.
