zstack - Configures the OpenArchitect switch stacking.

zstack [-h <host_name>] [-d <level>] [-a] [-t] [{-f <file>} | 

<configuration>]

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 Ethernet Switch Blade.   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.

-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. 

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
