Thanks JS. I think I got my answers now.

Hi,

you seem to have fairly basic questions related to the usage of SNMP and I am not sure this is the right place to get help. But anyway, if your device has network interfaces (very likely ;-), you should implement the IF-MIB. This MIB module defines among other things the OID 1.3.6.1.2.1.2.2.1.6. And note, you implement standard MIB objects under the OID they are registered; no need to copy stuff into your enterprise branch. Interoperability rests on the idea that everybody implementing a standard MIB module like say the IF-MIB does it with the same OIDs so that management applications can work with different devices.

He is trying to get the Physical address of the hardware using Get Request for the 1.3.6.1.2.1.2.2.1.6 and return nothing. Please see the screen capture and comments below. So my question is as a third party vendor we are normally only implementing MIB version 1(or MIB version 2) under our enterprise 1.3.6.1.4.1.4947 tree. So I don't see the iPhyAddress in our tree. So how should implement this for our customer? Or is the our responsibility to do? And is this field a mandatory field we had to implement? Where and how should I do that?

Spectrum uses the MAC address and compares it with the Switch ARP table to define where the device is connected. If the device is not responding to this OID request, Spectrum has no way to map it to the switch. This hinders fault isolation and troubleshooting. I have attached the results of a MIB 2 query. The device reports no results.  I would look to the engineering folks to see why the device does not respond to a MIB 2 query."
