z A port working in automatic voice VLAN assignment mode cannot be assigned to the voice VLAN
manually. Therefore, if a VLAN is configured as the voice VLAN and a protocol-based VLAN at the
same time, the protocol-based VLAN function cannot be bound with the port. For information about
protocol-based VLANs, refer to VLAN Configuration in this manual.
z For a port operating in automatic voice VLAN assignment mode, its default VLAN cannot be
configured as the voice VLAN; otherwise the system prompts you for unsuccessful configuration.
When the voice VLAN is working normally, if the device restarts, in order to make the established voice
connections work normally, the system does not need to be triggered by the voice traffic to add the port
in automatic voice VLAN assignment mode to the local devices but does so immediately after the restart
or the changes.
