Error-Cause Codes (RADIUS Attribute 101) for Dynamic Requests
When a RADIUS-initiated CoA or disconnect operation is unsuccessful, the router includes an error-cause attribute (RADIUS attribute 101) in the CoA-NAK or Disconnect-NAK message that it sends back to the RADIUS server. If the detected error does not map to one of the supported error-cause attributes, the router sends the message without an error-cause attribute. Table 1 describes the error-cause codes.
Table 1: Error-Cause Codes (RADIUS Attribute 101)
Code | Value | Description |
|---|---|---|
401 | Unsupported attribute | The request contains an attribute that is not supported (for example, a third-party attribute). |
402 | Missing attribute | A critical attribute (for example, the session identification attribute) is missing from a request. |
404 | Invalid request | Some other aspect of the request is invalid, such as if one or more attributes are not formatted properly. |
503 | Session context not found | The session context identified in the request does not exist on the router. |
504 | Session context not removable | The subscriber identified by attributes in the request is owned by a component that is not supported. |
506 | Resources unavailable | A request could not be honored due to lack of available NAS resources (such as memory). |
