User Guidelines
• The port is added to the voice VLAN if a packet with a telephony MAC address source MAC
address (defined by the voice vlan oui-table global configuration command) is trapped on the
port.
NOTE: The VLAN ID of the packet 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 telephony MAC addressed MAC address
ages out exceeds the timeout limit
( configured by the voice vlan aging-timeout global
configuration command), the port is removed from the voice VLAN.
