Configure a Trustpoint CA on Fabric IPsec Gateway VM

About this task

Use this procedure to configure the certificate authority (CA) to use Simple Certificate Enrollment Protocol (SCEP) with a CA server for online certificate provisioning.

Procedure

Enter Fabric IPsec Gateway Configuration mode:

enable

virtual-service WORD<1-128> console

Note

Type CTRL+Y to exit the console.
Configure the trusted CA URL:

set certificate ca-trustpoint <ca-label> ca-url <ca-url>
Configure the common name of the CA:

set certificate ca-trustpoint <ca-label> caname <caname>
Configure the HTTP request type to support the type of CA:

set certificate ca-trustpoint <ca-label> get-method <post | get>
Configure the appropriate action:
- Configure the trustpoint, authenticate the trustpoint CA by getting the certificate of the CA, and store the CA certificate locally:
  
  certificate ca <ca-trustpoint> caAuth
- Generate the certificate enrollment request, get the digital certificate, and store it locally, associating with the trustpoint CA:
  
  certificate ca <ca-trustpoint> enroll <subject-label>
- Get the Certificate Revocation List (CRL) from the CDP and store into a file:
  
  certificate get crl-from <A.B.C.D> <user> <file-path> <cacert-filename>
- Get the CA certificate obtained from the trustpoint CA:
  
  certificate get cacert-from <A.B.C.D> <user> <file-path>
- Get the subject certificate obtained from the trustpoint CA:
  
  certificate get signedcert-from <A.B.C.D> <user> <file-path> <subject-label>
- Release the locally stored certificate associated with the trustpoint CA after revocation:
  
  certificate ca <ca-trustpoint> remove <subject-label>
- Remove all certificates from the CA trustpoint:
  
  Note
  
  You can clean the CA trustpoint only if the subject-label is not configured on an IPsec tunnel.
  
  certificate ca <ca-trustpoint> clean
