The Remaining Age 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 the voice

VLAN aging time to 5 minutes, then after 5.5 minutes, a port will be

removed from 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 Remaining Age.

The following example configures the Voice VLAN aging time as 3000

Console(config)#voice vlan aging 3000

Console(config)#

This command specifies MAC address ranges to add to the OUI Telephony

list. Use the no form to remove an entry from the list.

Global Configuration

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.

same OUI (the first three octets). Other masks restrict the MAC address

[description description]

mac-address - Defines a MAC address OUI that identifies VoIP

devices in the network. (For example, 01-23-45-00-00-00)

mask-address - Identifies a range of MAC addresses. (Range: 80-

00-00-00-00-00 to FF-FF-FF-FF-FF-FF)

description - User-defined text that identifies the VoIP devices.

(Range: 1-32 characters)

a mask of FF-FF-FF-00-00-00 identifies all devices with the

FF-FF-FF-FF-FF-FF specifies a single MAC address.
