DESCRIPTION

The arlcontrol utility controls the operation of Aironet Ar

lan 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:

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 main

tained 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
