• In automatic voice VLAN assignment mode, a hybrid port can process only tagged voice traffic.
However, the protocol-based VLAN function requires hybrid ports to process untagged traffic. If a
VLAN is configured as the voice VLAN and a protocol-based VLAN at the same time, the
protocol-based VLAN cannot be associated with the port.
• Only one VLAN is supported and only an existing static VLAN can be configured as the voice
VLAN.
• If Link Aggregation Control Protocol (LACP) is enabled on a port, the voice VLAN function cannot
be enabled on it.
• After you assign a port working in manual voice VLAN assignment mode to the voice VLAN, the
voice VLAN takes effect.
