To do...
Configure the port to operate in
automatic voice VLAN
assignment mode
Enable voice VLAN on the port
An switch 4510G supports up to eight voice VLANs globally.
A protocol-based VLAN on a hybrid port can process only untagged inbound packets, whereas the
voice VLAN in automatic mode on a hybrid port can process only tagged voice traffic. Therefore,
do not configure a VLAN as both a protocol-based VLAN and a voice VLAN. For more information,
refer to Protocol-Based VLAN
Do not configure the default VLAN of a port in automatic voice VLAN assignment mode as the
voice VLAN.
