Port Status and Configuration
Using Friendly (Optional) Port Names
Configuring Transceivers and Modules That Haven’t
Been Inserted
Transceivers
Previously, a port had to be valid and verified for the switch to allow it to be
configured. Transceivers are removable ports and considered invalid when
not present in the switch, so they cannot be configured unless they are already
in the switch. For switches covered in this guide, the verification for allowable
port configurations performed by the CLI is removed and configuration of
transceivers is allowed even if they are not yet inserted in the switch.
Modules
You can create or edit configuration files (as text files) that can be uploaded
to the switch without the modules having been installed yet. Additionally, you
can pre-configure the modules with the CLI “module” command.
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.
Note 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.
Clearing the Module Configuration
Because of the hot-swap capabilities of the modules, when a module is
removed from the chassis, the module configuration remains in the configu-
ration file. This feature allows you to remove the module configuration
information from the configuration file.
