z
The voice VLAN function can be enabled for only one VLAN at one time.
z
If the Link Aggregation Control Protocol (LACP) is enabled on a port, voice VLAN feature cannot be
enabled on it.
z
Voice VLAN function can be enabled only for the static VLAN. A dynamic VLAN cannot be
configured as a voice VLAN.
z
When ACL number applied to a port reaches to its threshold, voice VLAN cannot be enabled on
this port. You can use the display voice vlan error-info command to locate such ports.
z
When a voice VLAN operates in security mode, the device in it permits only the packets whose
source addresses are the identified voice OUI addresses. Packets whose source addresses
cannot be identified, including certain authentication packets (such as 802.1x authentication
packets), will be dropped. Therefore, you are suggested not to transmit both voice data and service
data in a voice VLAN. If you have to do so, make sure that the voice VLAN does not operate in
security mode.
z
The voice VLAN legacy feature realizes the communication between H3C device and other
vendor's voice device by automatically adding the voice VLAN tag to the voice data coming from
other vendors’ voice device. The voice vlan legacy command can be executed before voice VLAN
is enabled globally and on a port, but it takes effect only after voice VLAN is enabled globally and
on the port.
z
When an S3100-C-EPON-EI switch works as an ONU device in the EPON system, the voice VLAN
function may not run properly. Therefore, it is not recommended to use the voice VLAN function in
the EPON system.
To assign a trunk port or a hybrid port to the voice VLAN, refer to VLAN Configurations of this manual
for the related command.
