Context
Ports can be added to a voice VLAN in either of the following modes:
l Automatic mode
A voice VLAN-enabled port learns source MAC addresses of frames from voice devices,
adds ports connecting the device to voice devices to a voice VLAN, and uses the voice
VLAN aging timer to control the number of ports in the voice VLAN. If a voice VLAN-
enabled port does not receive voice data from a voice device before the aging timer expires,
the port will be automatically deleted from the voice VLAN. If the port receives voice data
from the voice device again, the port will be automatically added to the voice VLAN.
l Manual mode
After the voice VLAN function is enabled, ports connected to voice devices must be
manually added to a voice VLAN. Otherwise, the voice VLAN function does not take
effect.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The view of a port connecting the device to users' voice devices is displayed.
Step 3 Run:
voice-vlan mode { auto | manual }
The mode in which ports are added to a voice VLAN is configured.
By default, ports are automatically added to a voice VLAN.
l If the auto parameter is configured, ports will be automatically added to a voice VLAN.
l If the manual parameter is configured, ports will be manually added to a voice VLAN.
– If trunk ports are connected to voice devices, run the port trunk allow-pass vlan
{ { vlan-id1 [ to vlan-id2 ] } &<1-10> | all } command to manually add these ports to a
voice VLAN.
– If hybrid ports are connected to voice devices, do as follows as required:
– Run the port hybrid untagged vlan { { vlan-id1 [ to vlan-id2 ] } &<1-10> | all }
command to manually add these ports to a voice VLAN in untagged mode.
– Run the port hybrid tagged vlan { { vlan-id1 [ to vlan-id2 ] } &<1-10> | all }
command to manually add these ports to a voice VLAN in tagged mode.
NOTE
In Access ports cannot be automatically added to a voice VLAN. To add a port of the access type to the
voice VLAN, run the port link-type command to change the port type to trunk or hybrid.
