Unable to discover individual contexts due to discovery utility removing all but one context as the Mac addresses are the same.

Problem:

We have recently upgraded our ASA firewalls, which consist of several virtual security contexts. After the upgrade, we have been unable to discover all the individual contexts due to the discovery utility removing all but one context as the mac addresses are the same. Our previous ASA, with the same number of security contexts, was able to be discovered. We are looking for some insight on how to accomplish this discovery once again.
 
Answer:
 
Are you running SNMPv3 to the ASA firewalls?
The discover duplicate MAC checking is skipped when the device is running
SNMPv3.
