+
+### 7.1 注册 Ruijie 设备（示例）
+
+如果已经在 `.env` 中配置了 Ruijie 的 NETCONF 代理（例如：`RUIJIE_NETCONF_HOST=127.0.0.1`、`RUIJIE_NETCONF_PORT=9830` 等），可以类似地注册一个 Ruijie 设备：
+
+```bash
+curl -s -X POST \
+  -H "Content-Type: application/json" \
+  -H "X-API-Token: changeme" \
+  -d '{
+    "name": "ruijie-live-1",
+    "host": "127.0.0.1",
+    "port": 9830,
+    "username": "ruijie1-admin",
+    "password": "******",
+    "enabled": true,
+    "supports_xpath": false,
+    "vendor": " Ruijie "
+  }' \
+  http://127.0.0.1:19100/api/v1/devices
+```
+
+API 会自动将 `vendor` 规范化为小写、去掉首尾空格，返回类似：
+
+```json
+{
+  "name": "ruijie-live-1",
+  "host": "127.0.0.1",
+  "port": 9830,
+  "enabled": true,
+  "scrape_interval_seconds": null,
+  "supports_xpath": false,
+  "source": "runtime",
+  "vendor": "ruijie"
+}
+```
