Voice VLAN Configuration

Caution:
z If the voice traffic sent by an IP voice device is tagged and the access port has
802.1x authentication and guest VLAN enabled, assign different VLAN IDs for the
voice VLAN, the default VLAN of the access port, and the 802.1x guest VLAN.
z If the voice traffic sent by the IP voice device is untagged, to realize the voice VLAN
feature, the default VLAN of the IP phone access port can only be configured as the
voice VLAN. Note that at this time 802.1 x authentication function cannot be
realized.
