Known Problems and Limitations
The following issues have been identified in the IMS AAA Server Release 1.1 software.
- Diameter statistics visible in the IMS AAA Server Administrator for Diameter Result-Code attribute value classes: Permanent Failures, Transient Failures and Protocol Errors, are updated based on Diameter Result-Code attribute values only, and not for Diameter Experimental-Result-Code attribute values. However, the corresponding SNMP traps are generated for both Diameter Result-Code and Experimental-Result-Code attribute values.
- Downstream RADIUS Dynamic Authorization clients are treated in the same manner as Upstream RADIUS Authentication and Accounting clients. Downstream RADIUS Dynamic Authorization clients can send access and accounting requests, and conversely, Upstream RADIUS Authentication and Accounting clients can send CoA/DM (Change of Authorization/Disconnect Messages) requests.
- The input material for Local Profile selection and Local Profile compilation - that is, HSS returned profile or Downstream server response - is captured during the very first authentication for the given user. This means that all subsequent authentications for the same user use the same material. See the "Local Profiles" and "Local Profile Selection" sections in the IMS AAA Server Administration Guide.
- The following statistical items are always reported as zero:
