If PKI certificates are not implemented on the switch, this requirement is not applicable. Step 1: Review the switch configuration to determine if a CA trust point has been configured as shown in the example below: crypto ca trustpoint CA_X enrollment terminal Step 2: Verify the CA is a DoD or DoD-approved service provider by entering the following command: show crypto ca certificates The output will list the following information for each certificate: Trustpoint (will map to a configured trustpoint from step 1) Common Name (CN) of the issuer Organization (O) of the issuer Organization Unit (OU) of the issuer Note: Cisco NX-OS software supports only the manual cut-and-paste method for certificate enrollment If the switch is not configured to obtain its public key certificates from a DoD or DoD-approved service provider, this is a finding.

Step 2: Verify the CA is a DoD or DoD-approved service provider by entering the following command: show crypto ca certificates

The output will list the following information for each certificate:

Trustpoint (will map to a configured trustpoint from step 1)
Common Name (CN) of the issuer
Organization (O) of the issuer
Organization Unit (OU) of the issuer
