User Guidelines
• The port is added to the Voice VLAN when a packet with a source MAC address that is a telephony
MAC address (defined by the Voice VLAN OUI-table Global Configuration command) is trapped on
the port.
NOTE: The packet VLAN ID can be the Voice VLAN ID, or any other VLAN. The port joins the Voice VLAN as a
tagged port. If the time since the last MAC address with telephony MAC address has aged out, exceeds the timeout
limit (configured by the Voice VLAN aging-timeout Global Configuration command), the port is removed from the
Voice VLAN.

Console (config)#
voice vlan aging-timeout minutes
Console (config)# voice vlan enable
