arlcontrol - configure Aironet Arlan 655 device

 

NAME

      arlcontrol - configure Aironet Arlan 655 device
 

SYNOPSIS

      arlcontrol iface
      arlcontrol iface country country (9-15)
      arlcontrol iface priority priority (normal, high, highest)
      arlcontrol iface txretry txretry
      arlcontrol iface stat
      arlcontrol iface quality
 

DESCRIPTION

      The arlcontrol utility controls the operation of Aironet Arlan 655 wire‐
      less 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 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 exam‐
      ple:
 
            #!/bin/sh
            /usr/sbin/arlcontrol country 9 priority highest
      arl(4)

BUGS

      Aironet Arlan 640 bridges and Arlan 630 access points do not understand
      country codes other than 9.

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
