> # Confirming CA Authentication

> As mentioned in step 5 of "Authenticating the CA" topic, CA authentication is required to be followed by CA confirmation in order to accept the CA certificate based on its fingerprint verification.

> ## Detailed Steps

> To confirm CA authentication, follow these steps:

> 1. Expand Switches > Security, and then select PKI in the Physical Attributes pane.
> 2. Click the Trust Point Actions tab in the Information Pane.
> 3. Make a note of the CA certificate fingerprint displayed in the IssuerCert FingerPrint column for the trust point row in question. Compare the CA certificate fingerprint with the fingerprint already communicated by the CA (obtained from the CA web site).

> If the fingerprints match exactly, accept the CA with the certconfirm command in the Command drop-down menu. Otherwise, reject the CA with the certnoconfirm command.

> 4. If you selected certconfirm in step 3, click Command and select the certconfirm action from the drop-down menu. Click Apply Changes.

> If you selected certnoconfirm in step 3, click Command and select the certnoconfirm action drop-down menu. Click Apply Changes.
