Configuring Rogue
Detection Lists

The following sections describe how to configure lists to specify the
devices that are allowed on the network and the devices that MSS should
attack with countermeasures.

(For information about how MSS uses the lists, see “Rogue Detection
Lists” on page 569.)

Configuring a

Permitted Vendor List

The permitted vendor list specifies the third-party AP or client vendors
that are allowed on the network. MSS does not list a device as a rogue or
interfering device if the device’s OUI is in the permitted vendor list.

By default, the permitted vendor list is empty and all vendors are allowed.
If you configure a permitted vendor list, MSS allows only the devices
whose OUIs are on the list. The permitted vendor list applies only to the
WX switch on which the list is configured. WX switches do not share
permitted vendor lists.

Countermeasures Packets sent by 3Com MAPs to

interfere with the operation of a
rogue or interfering device.

Countermeasures are configurable
on a radio-profile basis.
