設定 NSX-T Data Center 以使其與 Arista CVX 互動

在 NSX-T Data Center 上完成組態設定程序，以便可將 CVX 新增為 NSX-T Data Center 中的強制執行點，使 NSX-T Data Center 可與 CVX 互動。

必要條件

取得 Arista CVX 叢集的虛擬 IP 位址。

程序

以 root 使用者身分登入 NSX Manager，然後執行下列命令以擷取 CVX 的指紋：

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

輸出範例：

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

編輯所擷取的指紋，使其僅使用小寫字元，並在指紋中排除任何冒號。
編輯後的 CVX 指紋範例：
```

```

呼叫 PATCH /policy/api/v1/infra/sites/default/enforcement-points API，然後使用 CVX 指紋來為 CVX 建立強制執行端點。例如：

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",

}
}

呼叫 GET /policy/api/v1/infra/sites/default/enforcement-points API 以擷取端點資訊。例如：

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>",

}
}

輸出範例：

  },
  "auto_enforce": false,

  "_revision": 0
}

呼叫 POST /api/v1/notification-watchers/ API，然後使用 CVX 指紋來建立通知識別碼。例如：

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,

"authentication_scheme": {
"scheme_name":"BASIC_AUTH",
"username":"cvpadmin",
"password":"1q2w3e4rT"
}
}

呼叫 GET /api/v1/notification-watchers/ 以擷取通知識別碼。

輸出範例：

  "_protection": "NOT_PROTECTED",
  "_revision": 0
}

呼叫 PATCH /policy/api/v1/infra/domains/default/domain-deployment-maps/cvx-default-dmap API 以建立 CVX 網域部署對應。例如：

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"
