Default Setting

Global Configuration
Command Usage
• VoIP devices attached to the switch can be identified by the manufacturer’s Organizational Unique Identifier (OUI) in
the source MAC address of received packets. OUI numbers are assigned to manufacturers and form the first three
octets of device MAC addresses. The MAC OUI numbers for VoIP equipment can be configured on the switch so that
traffic from these devices is recognized as VoIP.
• Selecting a mask of FF-FF-FF-00-00-00 identifies all devices with the same OUI (the first three octets). Other masks
restrict the MAC address range. Selecting FF-FF-FF-FF-FF-FF specifies a single MAC address.
Example
The following example adds a MAC OUI to the OUI Telephony list.
Console(config)#voice vlan mac-address 00-12-34-56-78-90 mask
ff-ff-ff-00-00-00 description A new phone
Console(config)#
switchport voice vlan
This command specifies the Voice VLAN mode for ports. Use the no form to disable the Voice VLAN feature on the port.

Command Usage
When auto is selected, you must select the method to use for detecting VoIP traffic, either OUI or 802.1ab (LLDP) using
the switchport voice vlan command (page 4-251). When OUI is selected, be sure to configure the MAC address ranges
