Glen Z., has suggested the addition of counters in the event where the Session Context is not found for the RFC3576 MIBS. This requires the addition of 4 objects, one each for DM and CoA messages for both the client and server MIBs. There is a good need for this as NAKs could be sent for Diameter RAR capabilities, in which case the NAK is not an error condition.
Other Error Cause codes will not have corresponding counters. There is a security concern that the counter may provide information valuable for attacks. The authors would like to get the general feel for this.
Alternative, is to maintain a counter for requests that are for Diameter RAR capabilities.
Thanks and Regards,
