A Certificate Revocation List (CRL) is a list of certificate serial numbers that the issuing Certificate Authority (CA) says have been revoked, so that systems can be updated not to trust users that present those revoked certificates. If the edge gateway for your vCloud Director organization virtual datacenter has been converted to an advanced edge gateway, you can use the vCloud Director tenant portal to add CRLs to the edge gateway.

About this task

As described in the NSX Administration Guide, the CRL contains the following items:

  • The revoked certificates and the reasons for revocation

  • The dates that the certificates are issued

  • The entities that issued the certificates

  • A proposed date for the next release

When a potential user attempts to access a server, the server allows or denies access based on the CRL entry for that particular user.


To use the vCloud Director tenant portal to work with an edge gateway's settings, the edge gateway must be converted to an advanced edge gateway. You can do this on the edge gateway in the vCloud Director Web console or from the tenant portal. For details on performing this step from the tenant portal, see Convert an Edge Gateway to an Advanced Edge Gateway.


  1. Launch Edge Gateway Services by completing the following steps.
    1. Click Network > Edge Gateway.
    2. Select the edge gateway to edit, and click Configure Services.

      The tenant portal opens Edge Gateway Services.

  2. Click the Certificates tab.
  3. Click + CLR.
  4. Provide the CLR's data using one of these methods:
    • If the data is in a PEM file on a system you can navigate to, click the import button to browse to the file and select it.

    • If you can copy and paste the PEM data, paste it into the CRL (PEM format) field. Include the -----BEGIN X509 CRL----- and -----END X509 CRL----- lines.
