needed.
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 the WX3000 series devices
and other vendor's voice devices 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.
To add a Trunk port or a Hybrid port to the voice VLAN, refer to Basic Port Configurations of the 3Com
WX3000 Series Unified Switches Switching Engines Command Manual for the related command.
