    • The device loads the TPM-based certificate using PKI during the device's start and restart operations. To view the TPM-based certificate ID, referred to as idev-id, use the show security pki node-local local-certificate certificate-id idev-id command.

    • The SSL Initiation uses the certificate for Transport Layer Security (TLS) connection to authenticate the device. You can configure the tpm option using the set services ssl initiation profile profile-name crypto-hardware-offload command.
