In 2.0, the RFC 2619 and RFC 2621 MIBs are more fully supported than in 1.x. Note that re-transmitted responses to duplicate requests do not increment these counters. total responses = Access-Accepts + Access-Challenges + Access-Rejects Pending requests mean "live" requests that the server is currently processing. pending requests = total requests - duplicate requests - bad authenticators - malformed requests - unknown types - packets dropped - total responses The IPv6-aware MIBS, (RFC 4669 and RFC 4671) are not currently supported. Perhaps in 2.1. The client table for the server is also more fully supported than in 1.x. However, the RADIUS client MIBs (RFC 2618, RFC 2620, RFC 4668, and RFC 2670) are not supported. Perhaps in 2.1.
