Discovery Range Definition Options
When you set the range definition for your discovery processes, several options are available for how you want the discovery process to run.
|Discovery Type||Four types of scans are available for the discovery process:
|Root IPs||For Smart Scan only, provide the root IPs from which you want the Smart Scan to start.|
|Enter the domains you want to include or exclude from the discovery process.|
|Enter the zones you want to include or exclude from the discovery process.|
|Enter the IP addresses or host names you want to include or exclude from the discovery process.|
|Click the Edit icon to select devices that you want to include or exclude from the discovery process. Note that if you have entries for both of these option, the discovery process will prioritize included devices over excluded ones.|
|Do Not Ping
|To save time, FortiSIEM first attempts to reach devices by ping before initiating discovery. You should select this option if ping has been disabled for your network, otherwise discovery will fail.|
|Select this option if you are only interested in discovering whether a device or service is up or down.|
Devices not in
|If you select this option, discovery will only find those devices whose IP addresses do not match the address of any device in CMDB. To make an exception to this rule, specify a list of IP addresses in the Exclude Ranges field. The primary use case for this is for indirect device discovery such as VCenter-based VM discovery, or WLAN controller-based access point discovery. By specifying the VCenter IP address in the Exclude Ranges field, new guest VMs can always be discovered even if the VCenter is already in the CMDB.|
|By default, only powered on VMs are discovered.|
|By default, VM templates are not discovered.|
|Selected by default, if you clear this option then discovery will not use the route table to find next hop devices. This can be useful if your network includes border routers, which can significantly impact the time required for the discovery process.|
