Setting Default Description

RTS/CTS Maximum

Retries (1-255)

If RTS/CTS is enabled, this specifies the maximum number of times the AP

issues an RTS before stopping the attempt to send the packet through the

radio.

Acceptable values range from 1 to 128.

Maximum Data

Retries (1-255)

The maximum number of attempts the AP makes to send a packet before

giving up and dropping the packet. Acceptable values range from 1 to

255.

Beacon Period (19-

5000 msec)

100 Time between beacons (in microseconds).

DTIM Period (1-255) 2

DTIM alerts power-save devices that a packet is waiting for them. This

setting configures DTIM packet frequency as a multiple of the number of

beacon packets. The DTIM Interval indicates how many beacons equal

one cycle.

Ethernet

Encapsulation

RFC1042

This setting selects either the RFC1042 or 802.1h Ethernet encapsulation

standard for use by the group.

Radio Preamble Long

This setting determines whether the APs uses a short or long preamble.

The preamble is generated by the AP and attached to the packet prior to

transmission. The short preamble is 50 percent shorter than the long

preamble and thus may improve wireless network performance.

NOTE: Because older WLAN hardware may not support the short

preamble, the long preamble is recommended as a default setting in most

environments.

Table 62:

Groups > Radio > Radio Settings Fields and Default Values (Continued)

4. Certain wireless access points offer proprietary settings or advanced functionality that differ from prevailing industry

standards. If you use these APs in the device group, you may wish to take advantage of this proprietary functionality.

To configure these settings, locate the proprietary settings areas on the Groups > Radio page and continue with the

additional steps in this procedure.

Proprietary settings are only applied to devices in the group from the specific vendor and are not configured on devices

from vendors that do not support the functionality.

5. 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.

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 (#

of clients) on each card.

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

used in an AP-2000.
