During initial discovery, OpManager categorizes the network devices into servers, printers, switches, routers and firewalls. For proper classification, install and start the SNMP agent on all the managed devices.
The classified devices are placed under different maps for easy management.
Some devices are incorrectly classified if
the network devices do not support SNMP.
some devices have their SNMP settings different from those specified in the Discovery Settings dialog.
Perform the following tasks to ensure that OpManager maintains accurate information about your network:
Check the Device Template for the specific device type and make sure the correct category is selected.
Add a new Device Template if there isn't one.
Either when modifying an existing template or adding a new one, make sure that you query the device so that the correct sysOID is automatically populated. Proper categorization is done only when the device templates have correct configurations.
