N o t e

In the default stack configuration, the Candidate Auto Join parameter is

 

enabled, but the Commander Auto Grab parameter is disabled. This prevents

 

Candidates from automatically joining a stack prematurely or joining the

 

wrong stack (if more than one stack Commander is configured in a subnet or

 

broadcast domain). If you plan to install more than one stack in a subnet, HP

 

recommends that you leave Auto Grab disabled on all Commander switches and

 

manually add Members to their stacks. Similarly, if you plan to install a stack

 

in a subnet (broadcast domain) where stacking-capable switches are not

 

intended for stack membership, you should set the Stack State parameter (in

 

the Stack Configuration screen) to Disabled on those particular switches.
