Getting Started with Auto-Discovery
Brief run down on how-to quickly enumerate network objects in device42 appliance.
All discovered IP addresses will be placed in their respective subnets if subnets have been pre-defined. Otherwise, IPs end up in an “undefined” subnet.
Go to IPAM > Subnets, click on +Add Subnet on the top right corner.
The required fields are Name, Network and mask bits. Others are optional. The begin and end range are automatically calculated based on network and bits if left empty.
Installing and Running Auto-Discovery Client
The easiest way to enumerate windows and linux devices on the network is to use the .Net based auto-discovery client available for download at device42 auto-discovery page.
The installation is simple. Once you have it installed, run it from Start > All Programs > Device42 > D42AutoDisc.exe
Add url and credentials for your device42 appliance on the settings tab and head over to windows and linux tab to configure discovery.
Simply enter the IP range(or server names), credentials(if required) and start the discovery.
Linux tab requires username and password and Help tab has brief tips for this. Go to Documentation page for auto-discovery client for more info.
Device details like name, hardware model,serial #, CPU & RAM info, OS, MAC and IP info are populated depending on what is discovered.
Dealing with device type “unknowns”
Any devices that are not virtual will come over as device type “unknown” initially. The reason is that the appliance has not been told whether the hardware belongs to the physical, blade or other category.
The following device types have a hardware model. Each hardware model can be one of 3 types: regular, blade or other.
Regular: is for physical devices.
Blade: is for blade devices.
Other: is for other devices like laptops, workstations, network printers etc.(that are not rack mounted).
Once you change a hardware type, all the corresponding devices that refer to that hardware and are type unknown, will automatically be categorized accordingly.
in v311, we also introduced “bulk hardware edit” feature ,where you can change the hardware properties in bulk for all undefined hardware types and it will automatically categorize all devices belonging to it.
Also, once a hardware type is defined, any new imported or discovered devices will go into the right category.
