End-System reason 'End-System Session Detected'?

End-System reason 'End-System Session Detected'?

Not applicable


Have recently migrated a mobile providers APN device over to Extremecontrol. 

In the example below the third line down is a legitimate authentication requested from a mobile device, and these use PAP to authenticate.




The question is in relation to the lines shown in red.

When debugging requests shown below (IP’s and MAC’s have been masked), and further validated through a pcap, these are just accounting (port 1813) messages and not real authentication (port 1812) requests.

My question is if in XMC how does the End-systems show the distinction between the two i.e. what's a real request or not? I get you you shouldn’t really get accounting information without the original authentication request, so might be a corner case?

I see one difference in that just the accounting information has the ‘End-System Session Detected’, where as valid authentication requests show an actual rule, would that just be it?
