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.
