NAME
coqos_man - Set and monitor bandwidth
SYNOPSIS
coqos_man [options] limit [device] [...]
DESCRIPTION
This page is under construction.
Monitors the bandwidth being used and sets a bandwidth limit. If the bandwidth limit is exceeded it will
suspend the lower priority streams in priority order until the bandwidth being used is less than the
limit.
This program is part of the Qualcomm Atheros Powerline Toolkit. See the plc man page for an overview and
installation instructions.
OPTIONS
-e Redirects stderr messages to stdout. By convention progress messages and error messages are
printed on stderr while primary program output is printed on stdout. This option prints all
output on stdout in cases where this is desired.
-i interface
Select the host Ethernet interface. All requests are sent via this host interface and only
reponses received via this host interface are recognized. The default interface is eth1 because
most people use eth0 as their principle network connection; however, if environment string "PLC"
is defined then it takes precedence over the default interface. This option then takes precedence
over either default.
-q Suppresses status messages on stderr.
-r Display relative memory offsets on output. This option is the default.
-v Prints additional information on stdout. In particular, this option dumps outgoing Ethernet
packets on stdout.
-?,--help
Displays program help information on stderr. This option takes precedence over all other options
on the command line except version information.
-!,--version
Displays program version information on stderr. This option takes precedence over all other
options on the command line except help information. Use this option when sending screen dumps to
Atheros technical staff.
ARGUMENTS
limit The bandwidth limit, in kbps, expressed as a decimal integer. This argument is required. The
range is 10 through 90000.
device The MAC address of some powerline device. More than one address may be specified on the command
line. If more than one address is specified then operations are performed on each device in turn.
The default address is "local". See DEVICES for more information.
DEVICES
Ethernet MAC addresses are expressed as six hexadecimal octets optionally separated by colon. For
example, the Qualcomm Atheros Local Management Address (LMA) of "00b052000001" may also be entered as
"00:b0:52:00:00:01" or "00b052:000001". Addresses are case insensitive and quotes are optional. In
addition, some special addresses may be entered by name rather than number where names are case
sensitive.
all A synonym for the "broadcast" address, described next.
broadcast
A synonym for the Ethernet broadcast address, FF:FF:FF:FF:FF:FF. All devices, whether local,
remote or foreign will respond to this address.
local A synonym for the Qualcomm Atheros vendor specific Local Management Address (LMA),
00:B0:52:00:00:01. All local Atheros devices recognize this address but remote and foreign
devices do not. A remote device is any device at the far end of a powerline connection. A
foreign device is any device not manufactured by Atheros.
