DESCRIPTION

The arlcontrol utility controls the operation of Aironet Arlan 655 wireless networking devices via the arl(4) driver. Most of the parameters that can be changed are related to the Aironet protocol which the Aironet Arlan 655 card implements. The arlcontrol utility can also be used to view the current NIC status, configuration, and to dump out the values of the card’s statistics counters.

The iface argument given to arlcontrol should be the logical interface name associated with the Aironet Arlan 655 device (arl0, arl1, etc.) and must be specified.

OPTIONS

The options are as follows:

iface

Display current settings of the specified wireless interface. This retrieves current card settings from the driver and prints them out.

iface country country (9-15)

Chose country, channel parameters that depend on the country according to the following table:

Country Ch_Set MHz

North America 9 2412, 2427, 2442, 2457, 2465

iface priority priority (normal, high, highest)

Use the priority parameter to set the priority of the Arlan 655 Radio Media Access Control the values are normal, high or highest. The higher the priority is set, the more likely this unit will be the first to successfully transmit a packet when multiple units are trying to transmit at the same time.

The percentage of units on your network that you set to values other than normal should be kept small - 10 percent or less.

iface txretry txretry

Set transmit retries. Default is 0.

iface stat

Print internal Arlan 655 statistics block.

iface quality

Display the cached signal level and quality maintained by the arl(4) driver. The driver retains information about quality and level for packets received from different hosts. Also the driver extracts values from ACK packets.

EXAMPLES

arlcontrol arl0 country 11 priority high
arlcontrol arl0 quality
arlcontrol arl0 stat
arlcontrol arl0

You can configure the Arlan 655 card from /etc/start_if.arl0. For example:

#!/bin/sh
/usr/sbin/arlcontrol country 9 priority highest
