zstack
NAME
zstack - Configures the OpenArchitect switch stacking.
SYNOPSIS
zstack [-h <host_name>] [-d <level>] [-a] [-t] [{-f <file>} |
<configuration>]
DESCRIPTION
zstack combines multiple switch fabric chips into a single virtual switch. zstack must be run
before any other switch configuration. Specifically it must be run before zconfig. zstack is
typically run from an S20stack script prior to the S50xxx scripts. zstack currently only
supports directly connected switch chips as are present on the base switch. Directly connected
means that the local CPU can directly access and control the switch fabric chips being stacked.
zstack does not yet support network based stacking where there are separate boards with
separate CPUs controlling the switch fabric chips.
OPTIONS
-h <hostname> Specifies the remote hostname to configure. By
default, zstack configures stacking on the local OpenArchitect
switch. This option should only be used for displaying the
configuration, if at all.
-d <level> Sets the level of debugging output produced by zstack.
The default level is 1. Setting the debug level higher produces
more output. The maximum output level is currently four (4).
-a Displays the current stacking configuration of the switch.
-t Tears down the entire switch stacking configuration.
{-f <file>} | <configuration>
Gets configuration information from the specified file. A <file>
name of '+' reads configuration data from standard input. If the
-f flag is not used, a single line of configuration data can be
entered as parameters to zstack.
CONFIGURATION SYNTAX
zstack takes configuration data from standard input or from a file with the -f option. In either
case, the configuration syntax is the same. The zstack configuration data consists of a list of
