zqosd
NAME
zqosd
– monitors
tc(8)
commands to implement classification filters and queuing disciplines
in hardware.
SYNOPSIS
zqosd [-d <level>] [-p <port>] [-f] [-l] [-i <pid>] [-o <pid>]
DESCRIPTION
zqosd
monitors commands entered by
tc
which set up queuing disciplines and classification
filters for managing traffic in the switch. It supports a variety of queuing disciplines which allow
distributing available bandwidth at each output port of the switch among different classes of
traffic as well as selecting which packets to drop when bandwidth limits are exceeded.
zqosd
does not directly set up the hardware. It prepares messages describing the queuing
disciplines and filters and sends them to a hardware specific daemon,
ztmd
.
ztmd
should be
started before
zqosd
. Both programs normally run as background processes.
OPTIONS
-d <level> Set the level of diagnostic information logged.
<level> may be 0-4; higher levels produce more output.
- p <port> Use <port> as the multicast listening port for
communication with ztmd. Default is 2345.
-f Run zqosd in the foreground. Without this option, it is
run as a daemon.
-l Log diagnostic output to /var/log/zqosd.log
-i <pid> Set the pid for this process.
-o <pid> Set the pid of the destination process (ztmd)
EXAMPLES
Start the traffic management daemon,
ztmd
, then start
zqosd
to monitor
tc
output. Both
daemons are run as background processes and log their messages.
