zl2d
NAME
zl2d - Layer 2 daemon for the OpenArchitect switch.
SYNOPSIS
zl2d [start | stop] [-t <msecs>] [-d <level>] [-f]
DESCRIPTION
zl2d is run after the network interfaces are created and initialized with zconfig. zl2d
creates a Linux bridge for each interface using brctl(8). The bridge name is the interface
name with a 'b' pre-pended to it. This command is primarily used for Rapid Spanning Tree
Protocol (RSTP). Each port associated with the interface is included within the bridge. zl2d
starts a background task that continues throughout the life of the Layer 2 network. zl2d is a
script that can be modified to include brctl commands when started and stopped. Examine
/usr/sbin/zl2d for examples of how to change common options.
OPTIONS
start | stop
-t <msec> Cause zl2d to monitor the Spanning Tree state of
each port on each bridge every <msec> milliseconds. If
unspecified, the default is 500 milliseconds.
-f
the dynamic root priority.
-d <level> Sets the level of debugging output required by
zl2d. The default level is one (1). Setting the debug level
higher produces more output. Four (4) is currently the maximum
output level.
-p <priority>
should be specified as a decimal number.
disables root priority change.

operate. These network interfaces must first be created by
zconfig. zl2d does not operate with standard network interface
cards. It only works on switch network interfaces created by
zconfig.
