Aging Time:
Enter a period of time in hours to remove a port from voice VLAN if the port is an automatic
VLAN member. When the last voice device stops sending traffic and the MAC address of this voice device is
aged out, the voice VLAN aging timer will be started. The port will be removed from the voice VLAN after
expiration of voice VLAN aging timer. Selectable range is from 1 to 120 hours and default is 1 hour.
From Port / To Port:
A consecutive group of ports may be configured starting with the selected port.
Auto Detection:
Switch will add ports to the voice VLAN automatically if it detects the device OUI matches

setting and not impacted by QoS feature.

This window allows the user to configure the user-defined voice traffic’s OUI. An Organizationally Unique
Identifier (OUI) is the first three bytes of the MAC address. This identifier uniquely identifies a vendor,
manufacturer, or other organization.

There are some pre-defined OUIs and when the user configures personal OUI, these pre-defined OUIs must

user defined OUIs is 10. It will occupy one ACL rule when selecting user defined OUI by default, and to
configure one user-defined OUI will take extra one ACL rule. System will auto generate an ACL profile
(Profile ID: 51) for all the Voice VLAN rules.
