Rogue Detection Lists 423

Rogue Detection Rogue detection lists specify the third-party devices and SSIDs that MSS

Listsallows on the network, and the devices MSS classifies as rogues. You can

configure the following rogue detection lists:

„Permitted SSID list—A list of SSIDs allowed in the Mobility Domain. MSS generates a message if an SSID that is not on the list is detected.

„Permitted vendor list—A list of the wireless networking equipment vendors whose equipment is allowed on the network. The vendor of a piece of equipment is identified by the Organizationally Unique Identifier (OUI), which is the first three bytes of the equipment’s MAC address. MSS generates a message if an AP or wireless client with an OUI that is not on the list is detected.

„Client black list—A list of MAC addresses of wireless clients who are not allowed on the network. MSS prevents clients on the list from accessing the network through a WX switch. If the client is placed on the black list dynamically by MSS due to an association, reassociation or disassociation flood, MSS generates a log message.

„Known addresses list—A list of third-party devices that you want to exempt from rogue detection. MSS does not count devices on the ignore list as rogues or interfering devices, and does not issue countermeasures against them.

An empty permitted SSID list or permitted vendor list implicitly allows all SSIDs or vendors. However, when you add an entry to the SSID or vendor list, all SSIDs or vendors that are not in the list are implicitly disallowed.

An empty client black list implicitly allows all clients, and an empty ignore list implicitly considers all third-party wireless devices to be potential rogues.

All the lists except the black list require manual configuration. You can configure entries in the black list and MSS also can place a client in the black list due to an association, reassociation or disassociation flood from the client.

The rogue classification algorithm examines each of these lists when determining whether a device is a rogue. The following figure shows how the rogue detection algorithm uses the lists.
