For a voice VLAN operating in automatic mode, it does not support the adding of an Access port, and thus a voice VLAN cannot function when configuring with the VLAN VPN function.

For a voice VLAN operating in automatic mode, it only supports that the Hybrid port to process the tagged voice traffic. However, the protocol VLAN feature requires the Hybrid port to remove tags from the packets, see the VLAN part of this manual for details. Therefore, a VLAN cannot be configured as a voice VLAN and a protocol VLAN simultaneously.

For a port operating in automatic mode, a default VLAN cannot be configured as a voice VLAN; otherwise the system prompts you for unsuccessful configuration.
