Where does System Name, System Description, and Hostname come from and how are they kept up to date?
Release : 3.7
Component : IM Reporting / Admin / Configuration
System Name/System Description almost always comes from the MIB-II OIDs sysName and sysDescr.
This is for devices using the System Statistics Vendor Certification under the System Metric Family.
This is the vast majority of devices.
Some devices may not support theses OIDS so they use other OIDS such as:
Devices that use "Checkpoint System Statistics" for the System Metric Family use:
System Name: fwFilterName
System Description: fwProdName + ":" + fwFilterName
Devices that use the Cisco Meraki System Statistics VC:
System Name: sysDescr
System Description: sysDescr
The system name/system description would be updated during Inventory discovery
Hostname comes from DNS and is updated within 48 hours when changed:
