I can verify we have stumbled upon this as well.. We've been looking at it and found that while CA claims to recieve 220.127.116.11.4.1.789.3.6.X, all the mib entries are 18.104.22.168.4.1.789.3.0.X (they are ending in 3.6.X instead of 3.0.X). Looking at the mib definition there is no 3.6, so I assume it would default to 3.0. I'll log a case against it. Let you know what is the case.
