Configure NSX-T Data Center to interact with Arista CVX

Complete the configuration procedure on NSX-T Data Center so that CVX can be added as an enforcement point in NSX-T Data Center and NSX-T Data Center can interact with CVX.

Prerequisites

Obtain the virtual IP address for the Arista CVX cluster.

Procedure

1. Log in to NSX Manager as a root user and run the following command to retrieve the thumbprint for CVX:

   openssl s_client -connect <virtual IP address of CVX cluster> | openssl x509 -noout -fingerprint -sha256

   Sample output:

   depth=0 CN = self.signed
   verify error:num=18:self signed certificate
   verify return:1
   depth=0 CN = self.signed
   verify return:1
   SHA256 Fingerprint=35:C1:42:BC:7A:2A:57:46:E8:72:F4:C8:B8:31:E3:13:5F:41:95:EF:D8:1E:E9:3D:F0:CC:3B:09:A2:FE:22:DE

2. Edit the retrieved thumbprint to use only lower case characters and exclude any colons in the thumbprint.
   Sample of edited thumbprint for CVX:

   35c142bc7a2a5746e872f4c8b831e3135f4195efd81ee93df0cc3b09a2fe22de

3. Call the PATCH /policy/api/v1/infra/sites/default/enforcement-points API and use the CVX thumbprint to create an enforcement endpoint for CVX. For example:

   PATCH https://<nsx-manager>/policy/api/v1/infra/sites/default/enforcement-points/cvx-default-ep
   {
   "auto_enforce": "false",
   "connection_info": {
   "enforcement_point_address": "<IP address of CVX>",
   "resource_type": "CvxConnectionInfo",
   "username": "cvpadmin",
   "password": "1q2w3e4rT",
   "thumbprint": "65a9785e88b784f54269e908175ada662be55f156a2dc5f3a1b0c339cea5e343"
   }
   }
   

4. Call the GET /policy/api/v1/infra/sites/default/enforcement-points API to retrieve the endpoint information. For example:

   https://<nsx-manager>/policy/api/v1/infra/sites/default/enforcement-points/cvx-default-ep
   {
   "auto_enforce": "false",
   "connection_info": {
   "enforcement_point_address": "<IP address of CVX>",
   "resource_type": "CvxConnectionInfo",
   "username": "admin",
   "password": "1q2w3e4rT",
   "thumbprint": "35c142bc7a2a5746e872f4c8b831e3135f4195efd81ee93df0cc3b09a2fe22de"
   }
   }

   Sample output:

   {
     "connection_info": {
       "thumbprint": "35c142bc7a2a5746e872f4c8b831e3135f4195efd81ee93df0cc3b09a2fe22de",
       "enforcement_point_address": "192.168.2.198",
       "resource_type": "CvxConnectionInfo"
     },
     "auto_enforce": false,
     "resource_type": "EnforcementPoint",
     "id": "cvx-default-ep",
     "display_name": "cvx-default-ep",
     "path": "/infra/sites/default/enforcement-points/cvx-default-ep",
     "relative_path": "cvx-default-ep",
     "parent_path": "/infra/sites/default",
     "marked_for_delete": false,
     "_system_owned": false,
     "_create_user": "admin",
     "_create_time": 1564036461953,
     "_last_modified_user": "admin",
     "_last_modified_time": 1564036461953,
     "_protection": "NOT_PROTECTED",
     "_revision": 0
   } 

5. Call the POST /api/v1/notification-watchers/ API and use the CVX thumbprint to create a notification ID. For example:

   POST https://<nsx-manager>/api/v1/notification-watchers/
   {
   "server": "<virtual IP address of CVX cluster>",
   "method": "POST",
   "uri": "/pcs/v1/nsgroup/notification",
   "use_https": true,
   "certificate_sha256_thumbprint": "35c142bc7a2a5746e872f4c8b831e3135f4195efd81ee93df0cc3b09a2fe22de",
   "authentication_scheme": {
   "scheme_name":"BASIC_AUTH",
   "username":"cvpadmin",
   "password":"1q2w3e4rT"
   }
   }
   

6. Call the GET /api/v1/notification-watchers/ to retrieve the notification ID.
   Sample output:

   {
     "id": "a0286cb6-de4d-41de-99a0-294465345b80",
     "server": "192.168.2.198",
     "port": 443,
     "use_https": true,
     "certificate_sha256_thumbprint": "35c142bc7a2a5746e872f4c8b831e3135f4195efd81ee93df0cc3b09a2fe22de",
     "method": "POST",
     "uri": "/pcs/v1/nsgroup/notification",
     "authentication_scheme": {
       "scheme_name": "BASIC_AUTH",
       "username": "cvpadmin"
     },
     "send_timeout": 30,
     "max_send_uri_count": 5000,
     "resource_type": "NotificationWatcher",
     "display_name": "a0286cb6-de4d-41de-99a0-294465345b80",
     "_create_user": "admin",
     "_create_time": 1564038044780,
     "_last_modified_user": "admin",
     "_last_modified_time": 1564038044780,
     "_system_owned": false,
     "_protection": "NOT_PROTECTED",
     "_revision": 0
   }

7. Call the PATCH /policy/api/v1/infra/domains/default/domain-deployment-maps/cvx-default-dmap API to create a CVX domain deployment map. For example:

   PATCH https://<nsx-manager>/policy/api/v1/infra/domains/default/domain-deployment-maps/cvx-default-dmap
   {
   
   "display_name": "cvx-deployment-map",
   
   "id": "cvx-default-dmap",
   
   "enforcement_point_path": "/infra/sites/default/enforcement-points/cvx-default-ep"
   
   }
   

8. Call the GET /policy/api/v1/infra/domains/default/domain-deployment-maps API to retrieve the deployment map information.
