Parameter

Default

Function

 

 

 

Ad Hoc Channel

1

Use this parameter when the Radio Mode profile parameter is set to Ad Hoc.

 

 

Specifies the channel to be used for an Ad Hoc connection to another client de-

 

 

vice. If a channel is selected that is not supported by the by the radio, the default

 

 

value is used.

 

 

Options are:

 

 

• 1 through 14 (the 2.4GHz channels)

 

 

• 36, 40, 44, 48 (the UNII-1 channels)

 

 

 

Aggressive Scan

On

When set to On and the current connection to an AP weakens, the radio aggres-

 

 

sively scans for available APs.

 

 

Aggressive scanning works with standard scanning (set through Roam Trigger,

 

 

Roam Delta and Roam Period). Aggressive scanning should be set to On unless

 

 

there is significant co-channel interference due to overlapping APs on the same

 

 

channel.

 

 

Options are: On, Off

 

 

 

CCX Features

Optimized

Use of Cisco Compatible Extensions (CCX) radio management and AP speci-

 

 

fied maximum transmit power features.

 

 

This parameter cannot be changed.

 

 

 

WMM

Off

Use of Wi-Fi Multimedia extensions.

 

 

Options are: On, Off

 

 

Default value cannot be changed.

 

 

 

Auth Server

Type 1

Specifies the type of authentication server.

 

 

Options are: Type 1 (ACS server) and Type 2 (non-ACS server)

 

 

 

TTLS Inner

Auto-EAP

Authentication method used within the secure tunnel created by EAP-TTLS.

Method

 

Options are: AUTO-EAP (Any available EAP method), MSCHAPV2, MSCHAP,

 

 

PAP, CHAP, EAP-MSCHAPV2

 

 

 

PMK Caching

Standard

Type of Pairwise Master Key (PMK) caching to use when WPA2 is in use. PMK

 

 

caching is designed to speed up roaming between APs by allowing the client

 

 

and the AP to cache the results of 802.1X authentications, eliminating the need

 

 

to communicate with the ACS server. Standard PMK is used when there are no

 

 

controllers. The reauthentication information is cached on the original AP. The

 

 

client and the AP use the cached information to perform the four-way hand-

 

 

shake to exchange keys. Opportunistic PMK (OPMK) is used when there are

 

 

controllers. The reauthentication information cached on the controllers. The cli-

 

 

ent and the controller behind the AP use the cached information to perform the

 

 

four-way handshake to exchange keys.

 

 

If the selected PMK caching method is not supported by the network infrastruc-

 

 

ture, every roam requires full 802.11X authentication, including interaction with

 

 

the ACS server.

 

 

If the active profile is using WPA2 CCKM, the global PMK Caching setting is ig-

 

 

nored and the client attempts to use CCKM.

 

 

Options are: Standard, OPMK

 

 

Note: This change does not take effect until after a Suspend/Resume cycle.

 

 

 

WAPI

Off

Default is Off and dimmed (cannot be changed)

 

 

 

TX Diversity

On

How to handle antenna diversity when transmitting packets to the Access Point.

 

 

Options are: Main only, and On.

 

 

 

RX Diversity

On-Start on Main

How to handle antenna diversity when receiving packets from the Access Point.

 

 

Options are: On-Start on Main and Main only.

 

 

 

Frag Thresh

2346

If the packet size (in bytes) exceeds the specified number of bytes set in the

 

 

fragment threshold, the packet is fragmented (sent as several pieces instead of

 

 

as one block). Use a low setting in areas where communication is poor or where

 

 

there is a great deal of wireless interference.

 

 

This parameter cannot be changed.

 

 

 

RTS Thresh

2347

If the packet size exceeds the specified number of bytes set in the Request to

 

 

Send (RTS) threshold, an RTS is sent before sending the packet. A low RTS

 

 

threshold setting can be useful in areas where many client devices are associ-

 

 

ating with the Access Point.

 

 

This parameter cannot be changed.
