## Quick Start ## Quick Start
### 1. Configure your switches ### 1. Configure
Edit `mapper/config.py`: Copy `config.py.example` to `config.py` and fill in your values:
```bash
cp config.py.example config.py
nano config.py
```
```python ```python
SWITCHES = [ NOCODB_URL = "http://your-nocodb-host:8080"
"192.168.1.1", NOCODB_TOKEN = "your-api-token"
"192.168.1.2",
# Add all switch management IPs
]
SSH_USERNAME = "admin" SSH_USERNAME = "admin"
SSH_PASSWORD = "yourpassword" SSH_PASSWORD = "your-ssh-password"
SSH_PORT = 22
SSH_TIMEOUT = 30
DEVICE_TYPE = "cisco_ios"
``` ```
Switch IPs are pulled automatically from NocoDB — no manual list needed.
See [NocoDB Requirements](#nocodb-requirements) below.

## NocoDB Requirements
Switch inventory is loaded from NocoDB automatically. The table must have:
| Column | Description |
|--------|-------------|
| `IP` | Switch management IP — required |
| `Hostname` | Switch hostname |
| `Active` | Must be `YES` to be included in scans |
| `Dept` | Department code (e.g. `ELEC`, `GW`) — used for filtering |
| `Location` | Physical location label |
| `Model` | Switch model |
| `Manufacturer` | Switch manufacturer |
| `Asset Tag` | Asset tag |
The NocoDB base ID and table ID are hardcoded in `nocodb_client.py` — update them there if you point this at a different NocoDB instance.
## Troubleshooting ## Troubleshooting
**Auth errors**: Check SSH_USERNAME / SSH_PASSWORD in config.py **No switches loaded**: Check `NOCODB_URL` and `NOCODB_TOKEN` in `config.py`. NocoDB must return at least one row with `Active=YES` and a non-empty `IP`.
**Timeout errors**: Increase SSH_TIMEOUT in config.py (default: 30s) **Auth errors**: Check `SSH_USERNAME` / `SSH_PASSWORD` in `config.py`.
**Wrong device type**: If your FS switch uses a non-IOS CLI, try changing **Timeout errors**: Increase `SSH_TIMEOUT` in `config.py` (default: 30s).
