Summary
The data collected by Asset Discovery when scanning devices using the SNMP protocol is very limited. Only limited information beyond the hostname is retrieved.
Cause
The SNMP data out of the box is pretty limited, as described in Commands executed by Assets Discovery - SNMP.
Since every vendor can use SNMP MIBs in their own way, Atlassian can't know in advance which numbers provide the specific information. The SNMP patterns delivered with Discovery only have the MIB Information for some default SNMP Devices.
If you have the option to retrieve SNMP information using numeric OIDs by running an SNMP walk, you can see which MIBs provide which information.
Solution
You need to get the SNMP information using numeric OIDs by running an SNMP walk on the device. Then you will be able to see which MIBs deliver which information, and you can create your own custom Pattern.
Building a custom SNMP pattern is only worth the effort if you need specific attributes beyond hostname/basic identification for a device model you scan repeatedly (for example, fleet-wide network hardware) — for a one-off device, running a manual SNMP walk to inspect available OIDs, per the existing steps, is usually sufficient without building a reusable pattern.
There are some custom pattern examples that can be downloaded or used as inspiration for creating new ones to retrieve your specific device model.
