Zeroizing TPM Keys
Zeroizing a cryptographic module involves erasing sensitive parameters such as electronically stored data, cryptographic keys, and critical security parameters from a controller or an AP to prevent disclosure of information if the equipment is permanently and irreversibly decommissioned.
The following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. command erases the TPM Trusted Platform Module. TPM is an international standard for a secure cryptoprocessor, which is a dedicated microcontroller designed to secure hardware by integrating cryptographic keys into devices. content and renders the controller permanently inoperable.
Do not use this command prior to RMA Return Merchandise Authorization. RMA is a part of the product returning process that authorizes users to return a product to the manufacturer or distributor for a refund, replacement, or repair. The customers who want to return a product within its Warranty period contact the manufacturer to initiate the product returning process. The manufacturer or the seller generates an authorization number for the RMA, which is used by the customers, when returning a product to the warehouse., as it permanently decommissions a controller or an AP and voids any support or warranty entitlement.

The effect of the action you are about to execute is not reversible. Are you sure you want to implement this function? Press 'y' to proceed : [y/n]: y
This action will void the warranty on the controller and nullify the RMA. Are you still sure you want to do this?(y/n): y
You are about to wipe the contents of the TPM and render the controller permanently inoperable. Are you ready to go ahead?(y/n): y
TPM keys have been zeroized. Please reload the controller.

(host) [mynode] (config) #ap zeroize-tpm-keys <ap-name>/<ip-address>/<ipv6-address>
You are about to execute a command which will make the AP inoperable and void the RMA.
Are you sure you want to proceed? [y/n]: y
TPM keys have been zeroized. Please reboot the AP.
The following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. commands show the TPM Trusted Platform Module.
