Search for Devices
The process of searching for devices on a network and detecting the devices to be monitored and managed is called "discovery".
To perform discovery, specify an IP address range, subnet mask, or other settings for the search condition. The time required to perform discovery can be shortened, and the traffic load on the network can be lessened by limiting the range to perform the search. Select the best timing and method that least affects your business when performing discovery.
The following two methods of discovery are available:
- Network Search: A network search sends an SNMP authentication message to devices within a specified IP range.
- Broadcast Discovery: A broadcast search sends an SNMP authentication message to every client on the network at the same time, or to a specified subnet.
You need to perform discovery again in the following cases:
- To add a newly installed device to the device list
- To update the device list for the changes in the device IP address or host name
The devices are identified by the serial numbers or MAC addresses. Even when the IP address or host name of the device is changed, the device information is carried over if the device is determined to be the same device.
When only a small number of devices are being added, the devices can be added by specifying the device IP addresses individually. Refer to Add Devices Manually.
