Caution:
z You can enable voice VLAN feature for only one VLAN at a moment.
z If the Link Aggregation Control Protocol (LACP) is enabled for a port, the voice
VLAN feature can not be enabled for it.
z Voice VLAN function can be enabled only for the static VLAN. A dynamic VLAN can
not be configured as a voice VLAN.
z When the number of ACL applied to a port reaches to its upper limit, the voice VLAN
function can not be enabled for this port. You can use the display voice vlan
error-info command to locate such ports.
z When a voice VLAN operates in the security mode, the devices in it only permit
packets whose source addresses are the voice OUI addresses that can be identified.
Packets whose source addresses cannot be identified, including certain
authentication packets (such as 802.1x authentication packets), will be dropped. So,
do not transmit both voice data and service data in a voice VLAN. If you have to do
so, make sure the voice VLAN do not operate in the security mode.
 Note:
To add a Trunk port or a Hybrid port to the voice VLAN, refer to the Port Basic
Configurations part of the Quidway S3900 Series Ethernet Switches Command Manual
for the related command.
