VLAN ID:
Indicates the Voice VLAN ID. It should be a unique VLAN ID in the system and cannot equal
each port PVID. It is a conflict in configuration if the value equals management VID, MVR VID, PVID etc.
The allowed range is 1 to 4095.
Aging Time:
Indicates the Voice VLAN secure learning aging time. The allowed range is 10 to 10000000
seconds. It is used when security mode or auto detect mode is enabled. In other cases, it will be based on
hardware aging time. The actual aging time will be situated between the [age_time; 2 * age_time] interval.
Traffic Class:
Indicates the Voice VLAN traffic class. All traffic on the Voice VLAN will apply this class.
Mode:
Indicates the Voice VLAN port mode. When the port mode isn't equal disabled, we must disable
MSTP feature before we enable Voice VLAN. It can avoid the conflict of ingress filtering. Possible port
modes are:

:
Enable auto detect mode. It detects whether there is VoIP phone attached to the specific port and
configures the Voice VLAN members automatically.

Discovery Protocol:
Indicates the Voice VLAN port discovery protocol. It will only work when auto detect
mode is enabled. We should enable LLDP feature before configuring discovery protocol to "LLDP" or
"Both". Changing the discovery protocol to "OUI" or "LLDP" will restart auto detect process. Possible
discovery protocols are:
OUI
:
Detect telephony device by OUI (Organizationally Unique Identifier) address.
LLDP
