Command Usage
The Voice VLAN aging time is the time after which a port is removed from the Voice
VLAN when VoIP traffic is no longer received on the port.
The VoIP aging time starts to count down when the OUI’s MAC address expires from
the MAC address table. Therefore, the MAC address aging time should be added to
the overall aging time. For example, if you configure the MAC address table aging
time to 30 seconds, and voice VLAN aging time to 5 minutes, then after 5.5 minutes,
a port will be removed from the voice VLAN when VoIP traffic is no longer received
on the port. Alternatively, if you clear the MAC address table manually, then the
switch will also start counting down the voice VLAN aging time.
Note that when the switchport voice vlan command is set to auto mode, the
remaining aging time displayed by the show voice vlan command will be
displayed. Otherwise, if the switchport voice vlan command is disabled or set to
manual mode, the remaining aging time will display “NA.”
Example
The following example configures the Voice VLAN aging time as 3000 minutes.
Console(config)#voice vlan aging 3000
Console(config)#
