Syntax

Command Mode

User Guidelines
The port is added to the voice VLAN if a packet with a source MAC address
that is a telephony MAC address (defined by the voice vlan oui-table Global
Configuration mode command) is trapped on the port. Note: The packet
VLAN ID can be the voice VLAN ID or any other VLAN ID.
The port joins the voice VLAN as a tagged port.
If the time since the last MAC address with a telephony MAC address aged
out exceeds the timeout limit (configured by the voice vlan aging-timeout
Global Configuration mode command), the port is removed from the voice
VLAN.
Voice VLAN cannot be enabled on a port if the port is already a static member
of the defined Voice VLAN. This applies also to VLAN/switchport interface
modes (general, trunk and so on) that are not currently active on a port.
Therefore, before enabling voice VLAN on an interface, you must specifically
remove the Voice VLAN ID for any switchport mode for that interface in
which it is a member. Special attention is needed in relation to trunk mode
configuration, because in this mode, interfaces are members of all VLANs by
default.
Example
The following example enables OUI Voice VLAN 35 on gigabitethernet port
1/0/2. Note removal of VLAN 35 from interface trunk mode.
Console(config)# interface gi1/0/ 2
Console(config-if)# switchport trunk allowed vlan remove 35
Console(config-if)#
voice vlan enable
