z 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.
Therefore, 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.
z At present, only one VLAN is supported and only an existing static VLAN can be configured as the
voice VLAN.
z If Link Aggregation Control Protocol (LACP) is enabled on a port, the voice VLAN function cannot
be enabled on it.
z After you assign a port working in manual voice VLAN assignment mode to the voice VLAN, the
voice VLAN takes effect.
