The Voice VLAN working mode can be classified into the auto-mode and the manual-mode, and
configured on the port. The working modes for the Voice VLAN on each port are independent, and
different ports can work in different working modes. In different working modes, the methods of
enabling the Voice VLAN function on the port are different. The working mode can be set according to
the IP phone type connected downward the port or the port type.
1. With the Voice VLAN enabled on the port and in the manual mode, this port must be added to
the Voice VLAN manually to ensure the function validity.
2. When the port works in the auto-mode, note that the native VLAN of the port cannot be set as
the Voice VLAN for the normal function performance.
3. The Trunk Port/Hybrid Port on the Ruijie product can transmit the packets in all VLANs by
default. First remove the Voice VLAN from the allowed VLAN list for the port, then enable the
Voice VLAN to ensure that the port disconnecting with the voice device cannot be added to the
Voice VLAN, or the port not used for a long time can be still in the Voice VLAN.
1. With the Voice VLAN enabled on the port, the auto and manual modes switchover is
disallowed. Disable the Voice VLAN first if it is necessary to switch the modes.
2. In the auto mode, it fails to add/remove the port to/from the Voice Vlan by using the
command.
The following example sets the Voice VLAN on the interface FastEthernet 0/1 to work in the auto
mode.
Ruijie(config)# interface fastEthernet 0/1
Ruijie(config-vlan)# voice vlan mode auto
