Displaying the Backplane and Serial Number Information
You can display the backplane information, including the serial number for the switch by using the
show
sprom backplane
command.
Displaying Environmental Information for the Switch
You can display all the environment-related switch information by using the
show environment
command.
Displaying the Current State of a Module
You can display information about modules that are installed in the switch chassis by using the
show module
command. This information includes module type, bootup status, MAC addresses, serial numbers, software
versions, and hardware versions. You can use this command in the following ways to display information
about all the installed modules or a specific module:
• For information on all modules, use the
show module
command.
• For information on a specific supervisor, system controller, line card, or fabric module, use the
show
module slot_number
command to specify a slot number.
To determine the slots to specify, use the
show inventory
command.
Note
This command reports on only software-controlled modules, such as supervisors, system controllers, line
cards, fabric modules, fan trays, and power supplies. It doesn’t report on modules that are not software
controlled, such as blank modules installed in empty slots to control airflow.
Note
This table provides descriptions of the module status that is displayed with the
show module
commands.
