+# Automation
+
+## Upload
+
+You can automate upload of the firmware via WEB with curl:
+
+1. Authorize with /login endpoint and save cookie:
+
+   ```bash
+   curl -c cookies.txt  http://${SWITCH_IP}/login -d pwd=${PASSWORD} -i
+   ```
+
+   This will save session cookie in cookies.txt
+2. Send the firmware via form:
+
+    ```bash
+    curl -b cookies.txt http://${SWITCH_IP}/upload -F "uploadedfile=@${FIRMWARE_FILE_PATH}" -i
+    ```
+
+    You can expect that server will close connection, without responding to request.
+    Wait for SWITCH_IP to be responding again.
+
+## Port status
+
+In similar way to upload, you can fetch the json status of the ports.
+
+1. Get the session cookie as for upload.
+2. Hit the `/status.json` with cookie:
+
+    ```bash
+    curl -b cookies.txt http://${SWITCH_IP}/status.json
+    ```
