z A port working in automatic voice VLAN assignment mode cannot be assigned to the voice VLAN

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.

configured as the voice VLAN; otherwise the system prompts you for unsuccessful configuration.
