Parameter description:
Mode :
Indicates the Voice VLAN mode operation. We must disable MSTP feature before we
enable Voice VLAN. It can 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. 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.
Port 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:
Disabled: Disjoin from Voice VLAN.
Auto: Enable auto detect mode. It detects whether there is VoIP phone attached to the
specific port and configures the Voice VLAN members automatically.
Forced: Force join to Voice VLAN.
Port Security :
Indicates the Voice VLAN port security mode. When the function is enabled, all
non-telephonic MAC addresses in the Voice VLAN will be blocked for 10 seconds. Possible
port modes are:
Enabled: Enable Voice VLAN security mode operation.
Disabled: Disable Voice VLAN security mode operation.
Port 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 address.
LLDP: Detect telephony device by LLDP.
Both: Both OUI and LLDP.
