What are subnets?
In network monitoring, subnets are smaller portions of a larger IP address range, that help technicians manage and monitor network devices more efficiently.
You can connect to subnets in two ways:
Through a probe: If a network’s probe is connected to a subnet, then you can use the probe to run a network scan and access all the network devices connected to that particular subnet
A subnet that is reachable by the probe but not directly connected to it can be manually added to scan network devices.
Since the first method of connecting to a subnet happens automatically, let’s look at how you can manually add subnets.
Manually adding subnets
While subnets are automatically fetched for some clients and sites, you can manually custom subnets in the network that you want to monitor. Here's how:
Navigate to Modules > Network monitor > Network Scans
Click the +Subnet button on the top right corner, as shown below.
3. Now, select a client and site for which you want to associate the subnet.
4. Enter the subnet addresses and hit save once you are done.
5. These subnets will now be linked to the specified client and site.
6. Keep in mind that for subnet scans to occur, there must be probes and credentials associated with the selected client and site.
7. You can create a new probe or credential from the same page by clicking on the Add Credential or Create Probe button.
