The fields that can be configured are described below: 
Parameter  Description 
Unit 
Select the Switch unit that will be used for this configuration here. 
From Port - To Port 
Select the range of ports that will be used for this configuration here. 
State 
Select to enable or disable the voice VLAN feature on the specified port(s) here. 
When the voice VLAN is enabled for a port, the received voice packets will be 
forwarded in the voice VLAN. The received packets are determined as voice 
packets if the source MAC addresses of packets complies with the OUI 
addresses. 
Mode 
Select the mode here. Options to choose from are: 
•  Auto Untagged - Specifies that voice VLAN untagged membership will be 
automatically learned. 
•  Auto Tagged - Specifies that voice VLAN tagged membership will be 
automatically learned. 
•  Manual - Specifies that voice VLAN membership will be manually 
configured. 
If auto-learning is enabled, the port will automatically be learned as a voice VLAN 
member. This membership will automatically be aged out. When the port is 
working in the auto-tagged mode and the port captures a voice device through the 
device's OUI, it will join the voice VLAN as a tagged member automatically. When 
the voice device sends tagged packets, the Switch will change its priority. When 
the voice device sends untagged packets, it will forward them in the Port VLAN ID 
(PVID). 
When the port is working in auto-untagged mode, and the port captures a voice 
device through the device's OUI, it will join the voice VLAN as an untagged 
member automatically. When the voice device sends tagged packets, the Switch 
will change its priority. When the voice device sends untagged packets, it will 
forward them in the voice VLAN. 
When the Switch receives LLDP-MED packets, it checks the VLAN ID, tagged 
flag, and priority flag. The Switch should follow the tagged flag and priority setting.
