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.

ztmd –l zqosd -l
