Hi
I am trying to use Flexible Netflow on Virtual-Access Interfaces which are used by PPPoE subscribers.
Solution works fine as far as the PPPoE session is up and accordingly the Virtual-Access Interface is up.
The Case is when we have a disconnection from Router, No Netflow Information is sent to Exporter. It seems as soon as interface is considered down(Because of PPPoE disconnection) Contents of Netflow cache for that interface is cleared.
I am using ASR1001X with following IOS:
asr1001x-universalk9.03.13.03.S.154-3.S3-ext.SPA
I am comparing this behavior to RADIUS. With RADIUS as soon as we have a disconnection, Router will send a Accounting Stop to RADIUS server and includes the traffic usage of PPPoE session inside of it....
Thank you
Peyman
