> # Ensuring Trust Point Configurations Persist Across Reboots

> The trust point configuration is a normal Cisco NX-OS configuration that persists across system reboots only if you copy it explicitly to the startup configuration. The certificates, key pairs, and CRL associated with a trust point are automatically persistent if you have already copied the trust point configuration in the startup configuration. Conversely, if the trust point configuration is not copied to the startup configuration, the certificates, key pairs, and CRL associated with it are not persistent since they require the corresponding trust point configuration after a reboot. Always copy the running configuration to the startup configuration to ensure that the configured certificates, key pairs, and CRLs are persistent. Also, save the running configuration after deleting a certificate or key pair to ensure that the deletions are permanent.

> The certificates and CRL associated with a trust point automatically become persistent when imported (that is, without an explicitly copying to the startup configuration) if the specific trust point is already saved in startup configuration.

> We also recommend that you create a password-protected backup of the identity certificates and save it to an external server (see the "Exporting and Importing Identity Information in PKCS#12 Format" topic).

> Note Copying the configuration to an external server does include the certificates and key pairs.
