Allied Telesis AT-S112, AT-GS950/16PS manual 260

Chapter 20: 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 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.
