I've come across these two contradictory statements in the Yusuf flash cards, in two different explanations about the RADIUS packet header.
In one question, the explanation states: When troubleshooting and reading RADIUS debugs, the code field is very handy in interpreting and understanding the debug outputs. And then in the next question, the explanation states: When troubleshooting and reading RADIUS debugs, the ID field is very handy in interpreting and understanding the debug outputs. The question asked was:"Which field in the RADIUS packet assists in making the debugs more user friendly and easy to interpret?". I stated the "Code" field, which is marked wrong because of the above (2nd) explanation. My understanding is that the Code field identifies the type of Radius packet such as Access-Request, Access-Reject, etc. While the "identifier" field is used for matching the request and reply packets. Essentially, both used together would make troubleshooting the debugs a whole lot easier, but since the question only requires one, to me the "Code" field makes the debugs more user friendly, since all the Identifier field is going to tell me is which Request packet I should match a specific reply packet to. Would this just be a typo or is my interpretation wrong ? Mark
