Syntax: module <module-num> type <module-type>
Allows you to configure the type of the module.
The same module command used in an uploaded configuration file is used to
define a module that is being pre-configured. The validation performed when
issued through the CLI is still performed just as if the command was executed
on the switch, in other words, as if the module were actually present in the
switch.
N o t e You cannot use this method to change the configuration of a module that has
already been configured. The slot must be empty and the configuration file
must not have a configuration associated with it.
