After the voice VLAN function is enabled on a port, do not switch the L2 mode (trunk or access mode) of
the port to ensure normal operation of the function. If you need to switch the L2 mode of the port, disable
the voice VLAN function on the port first.
●
It is not recommended that both voice data and service data be transmitted over the voice VLAN. If you
want to transmit both voice data and service data over the voice VLAN, disable the voice VLAN function
in security mode.
●
The voice VLAN function is unavailable on L3 ports or aggregate ports.
