Hi Ludo, thanks. Yes, 1.3.6.1.4.1.311.1.1.3.1.1 can also translate to
Windows-NT-Perfomance if i use WINDOWS-NT-PERFORMANCE.mib. And
1.3.6.1.4.1.311.1.1.3.1.1.4 translates to (pdiskphysicalDiskTable). So
the same OID can be translated differently by different MIBs.
I've done another test, here's the Wireshark trace. Note, this trap is
captured whenever i restart Windows SNMP Service - I've added the trap
destination which i run the trap receiver daemon.
No. Time Source Destination Protocol
