I certainly agree with the point that accounting records shouldn't be used alone for concurrency control. In my case I have a single radius server (that may be the problem;) and am trying to figure out why only one chassis has this problem. There have been so many great tips come out of this list as I lurk in the shadows that I have taken advantage of, I was hoping someone may have come across this problem.

Thus spake Mark Thornton
There has been a fair amount of discussion about missing radius records, specifically stop records as regards to concurrency control. I posted a question about this a week or so back and didn't get a response. In my case I have a single chassis that is prone to this problem, but the others are not. Any ideas why?
Also, if getting the stop record is so unreliable how do those of you who do hourly billing keep the system working? In our case the session is lost and not billed for. I can live with that but it bothers me that it isn't reliable.
Its not so much that the stop records are unreliable...the RADIUS standard indicates that RADIUS accounting is resent, to ensure that it gets through (unlike syslog which sends it once...if it doesn't get through...so sorry). The problem is really that if you have multiple RADIUS servers for redundancy, the start may get sent to one and the stop to the other, and its difficult to coordinate this between your RADIUS servers.
Also its just the whole idea of forcing state on what's designed to be a stateless protocol (RADIUS). -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456
