Configuring a port to operate in manual voice VLAN
assignment mode
Configuration restrictions and guidelines
When you configure a port to operate in manual voice VLAN assignment mode, follow these
restrictions and guidelines:
• You can configure different voice VLANs on different ports on the same device. Make sure the
following requirements are met:
{ One port can be configured with only one voice VLAN.
{ Voice VLANs must be existing static VLANs.
• Do not enable voice VLAN on the member ports of a link aggregation group. For more
information about link aggregation, see "Configuring Ethernet link aggregation."
• For a port that is enabled with voice VLAN and operating in manual mode, you must manually
assign the port to the voice VLAN to make the voice VLAN take effect.
