Custom

The parameter value is displayed as “Custom” when the operating system registry has been edited to set the Summit parameter to a value that is not available from the parameter’s drop down list. Selecting Custom from the drop down list has no effect. Selecting any other value from the drop down list will overwrite the “custom” value in the registry.

Global Parameters

Parameter

Default

Function

 

 

 

Roam Trigger

-65 dBm

If signal strength is less than this trigger value, the client looks for a dif-

 

 

ferent Access Point with a stronger signal.

 

 

Options are: -50 dBm, -55, -60, -65, -70, -75, -80, -85, -90 dBm or

 

 

Custom (page 8-11).

 

 

 

Roam Delta

5 dBm

The amount by which a different Access Point signal strength must ex-

 

 

ceed the current Access Point signal strength before roaming to the dif-

 

 

ferent Access Point is attempted.

 

 

Options are: 5 dBm, 10, 15, 20, 25, 30, 35 dBm or Custom (page 8-11)

 

 

 

Roam Period

ABG: 10 sec.

The amount of time, after association or a roam scan with no roam, that

 

 

the radio collects Received Signal Strength Indication (RSSI) scan data

 

 

before a roaming decision is made.

 

 

Options are: 5 sec, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 seconds or

 

 

Custom (page 8-11).

 

 

 

BG Channel Set

Full

Defines the 2.4GHz channels to be scanned for an AP when the radio

 

 

is contemplating roaming. By specifying the channels to search, roam-

 

 

ing time may be reduced over scanning all channels.

 

 

Options are:

 

 

Full (all channels)

 

 

1,6,11 (the most commonly used channels)

 

 

1,7,13 (for ETSI and TELEC radios only)

 

 

or Custom (page 8-11)

 

 

 

DFS Channels

Off

Support for 5GHZ 802.11a channels where support for DFS is required.

 

 

Options are: On, Off.

 

 

Not supported (always off) in some releases.

 

 

 

DFS Scan Time

120 ms.

ABG radio only. The amount of time the radio will passively scan each

 

 

DFS channel to see if it will receive a beacon.

 

 

Recommended value is 1.5 times that of the AP's beacon period.

 

 

 

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 device. 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

 

 

aggressively 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 or

ABG: Optimized

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

CCX Features

 

specified maximum transmit power features.

 

 

This parameter cannot be changed.

 

 

 

WMM

Off

Use of Wi-Fi Multimedia extensions.

 

 

Options are: On, Off

 

 

Devices running Windows XP can change the default value. Devices

 

 

running all other OS cannot change the default value.

 

 

 

Auth Server

Type 1

Specifies the type of authentication server.

 

 

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