zl2d
NAME
zl2d - Layer 2 daemon for the OpenArchitect switch.
SYNOPSIS
zl2d [start | stop] [-t <msecs>] [-d <level>] [-f]
[-p <priority>] <iface..>
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 Spanning Tree Protocol
(STP). 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 Starts or stops the zl2d daemon.
-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 Enables Fast Forward on bridge(s) using 0x4000 (16384) as
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> Sets the dynamic root priority. <priority> should
be specified as a decimal number. A priority of 0 disables root
priority change.
<iface…> The network interfaces on which zl2d should 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.
