You will now see the below page. If you want to scan 192.168.1.0/24, you would
enter that in the subnet range textbox then enter the subnet in CIDR format.

Other important options are

| Option                     | Description                                                                                |
| -------------------------- | ------------------------------------------------------------------------------------------ |
| Schedule type              | How often you want to scan this subnet for devices                                         |
| Discovery threads          | How many proccessess to spawn during the scan                                              |
| Max Runtime                | to prevent the scan from running indefinitely                                              |
| Automatically add to Cacti | If a device is SNMP reachable and matches a rule from this subnet the device will be added |
| Netbios                    | Attempt to resolve the hostname by netbios                                                 |

After you are done adding your network details, ensure you enable the rule and
save.

Ensure that if you have a SNMP rule for this part of the network to select the
SNMP option set this will tie the network to the SNMP rules
