Thank you for your answer.
I downloaded the folder PMP45x MIBS 15.2. this folder contains several files (see attached screenshot). my question as to which of these files is the MIB file containing the PMP450i OIDs
thank you for your comeback
Are you looking for a specific OID, or the complete MIB?
What are you trying to accomplish with the equipment?
I would recommend a tool like the iReasoning MIB Browser to walk the MIB and find what which OID you might need to access for a given SNMP command.
