Support For Voice Vlan On Various Ports - H3C S5600 Series Operation Manual

Operation Manual – Voice VLAN
H3C S5600 Series Ethernet Switches
Caution:
If the voice traffic transmitted by an IP voice device carries VLAN tags, and 802.1x
authentication and guest VLAN is enabled on the port which the IP voice device is
connected to, assign different VLAN IDs for the voice VLAN, the default VLAN of the
port, and the 802.1x guest VLAN to ensure the effective operation of these
functions.
If the voice traffic transmitted by an IP voice device carries no VLAN tag, the default
VLAN of the port which the IP voice device is connected to must be configured as
the voice VLAN. In this case, the 802.1x authentication is unavailable.

port configuration. For IP phones capable of acquiring IP address and voice VLAN
