Chapter 3: Configuration
Parameter Description
• Mode: Indicates the Voice VLAN mode operation. Disable the MSTP feature before enabling Voice VLAN to avoid the conflict
of ingress filtering. Possible modes are:
Enabled: Enable Voice VLAN mode operation.
Disabled: Disable Voice VLAN mode operation.
• VLAN ID: Indicates the Voice VLAN ID. This 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 valid range is 1 to 4095.
• Aging Time: Indicates the Voice VLAN secure learning aging time. The 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 to this class.
• Port Mode: Indicates the Voice VLAN port mode. When the port mode isn’t equally disabled, first disable MSTP feature before
enabling Voice VLAN, to avoid the conflict of ingress filtering.

Voice VLAN members automatically.

enabled. Enable the LLDP feature before configuring discovery protocol to “LLDP“ or “Both.“ Changing the discovery protocol
to “OUI“ or “LLDP“ will restart the autodetect process. Possible discovery protocols are:
OUI: Detect telephony device by OUI address.
LLDP: Detect telephony device by LLDP.
