The Voice VLAN feature enables voice traffic forwarding on the Voice VLAN, then
the switch can classify and schedule network traffic. It is recommended that there be
two VLANs on a port - one for voice, one for data. Before connecting the IP device to
the switch, the IP phone should configure the voice VLAN ID correctly. It should be
configured through its own GUI.
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. 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.
