8. Locate the Groups > VxWorks section and adjust these settings as required. Table 62 describes the settings

and default values of this page.

9. To configure settings specific to the Proxim AP-600, AP-700, AP-2000, AP-4000; Avaya AP-3/4/5/6//7/8, and

ProCurve 520WL, locate the appropriate section of Groups > Radio page and define the required fields.

Table 63 describes the settings and default values.

Rogue Scan Interval (30-

10080 min)

720 Specifies the time, in minutes, between rogue scans.

Rogue Scan Duration

(200-1000 msec)

350 Specifies the amount of time, in milliseconds, the AP listens to rogues before returning

to normal operation.

Table 62 Groups > Radio > VxWorks Fields and Default Values

Setting Default Description

Use Aironet

Extensions

Yes When enabled, this option allows Cisco devices to provide functionality not supported by

802.11 IEEE standards, including the following:

 Load balancing—Allows the access point to direct Aironet clients to the optimum access

point.

 Message Integrity Check (MIC)—Protects against bit-flip attacks.

 Temporal Key Integrity Protocol (TKIP)—Key hashing algorithm that protects against IV

attacks.

Lost Ethernet

Action

Repeater

Mode

Pull-down menu that specifies the action to take when the Lost Ethernet Timeout threshold is

exceeded:

 No Action—No action taken by the AP.

 Repeater Mode—The AP converts to a repeater, disassociating all its clients while the

backbone is unavailable. If the AP can communicate with another root AP on the same

SSID, its clients will be able to re-associate and connect to the backbone. If the AP

cannot communicate with another root AP, clients are not allowed to re-associate.

 Disable Radio—The AP disassociates its clients and disables the radio until it can

establish communication with the backbone.

 Restrict SSID—The AP disassociates all clients and then allows clients to re-associate

with current SSID.

Lost Ethernet

Timeout

(1-1000 secs)

2 Specifies the time (in seconds) the AP waits prior to taking action when its backbone

connectivity is down. Actions are defined in the Lost Ethernet Action field.

Upgrade Radio

Firmware When

AP Firmware Is

Upgraded

Yes If enabled, this setting mandates that the radio firmware be upgraded to a firmware version

compatible with the current version of AP firmware.

Table 63 Groups > Radio > Proxim/Avaya/Procurve APs Fields and Default Values

Setting Default Description

Load Balancing No If enabled, this setting allows client devices associating to an AP with two radio cards

to determine which card to associate with, based on the load (number of clients) on

each card.

NOTE: This feature is only available when two 802.11b wireless cards are used in an

AP-2000.

Interference Robustness No If enabled, this option will fragment packets greater than 500 bytes in size to reduce

the impact of radio frequency interference on wireless data throughput.
