Znyx Networks bh5700 manual Zl2d Layer 2 daemon for the OpenArchitect switch, Start stop

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 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 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.
