Hi All,

 

I have a few questions about the “Accounting-Start” and “Accounting-Off”.

 

1.       If a NAS configured to have a primary and a backup RADIUS server. To start with all the “Accounting-Start” records will be in the primary RADIUS server. Later on the primary server goes down (Primary server won’t tell the NAS?). When sessions stop, the NAS sends the “Accounting-Stop” to the secondary. I understand the “Start-Stop” record with the same “user name” and “session-id” ideally should be recorded in the same server. If this situation happens what should both the NAS and RADIUS server do?

2.       A NAS configured to have a primary and backup RADIUS server. To start with all the “Accounting-Start” records will be in the primary RADIUS server. Later on the administrator decided to change the primary server (as there are problems with the previous primary). sessions stop, the NAS sends the “Accounting-Stop” to the new primary. This ends up the “Accounting-Start” and “Accounting-Stop” with the same “user name” and “session Id” in two RADIUS servers.

 

To summarize, how to avoid the ”start-stop” pair ends up in different servers ? If it does, is it  an issue for RADIUS application ?

 

 

Cheers,
