Hi
I want to change my accounting System From RADIUS to Netflow(Flexible)for PPPoE users on an ASR1001-X.
I have some questions about this task:
1- Is there any configuration to pass Username of Subscriber inside the Netflow records?
In this case subscriber is still authenticated via RADIUS, so RADIUS will not be removed completely.
2- Beside that when I tested the solution without Username Information and Just IP address I found out when subscriber is downloading from one Server, The usage is recorded and it is passed to Netflow Exporter but When the subscriber downloads from two different servers the usage information is not passed to exporter and It is not recorded. I still can see the info in RADIUS accounting packets Here is my configuration(I kept it for comparison tests):
ASR1001X#show running-config | section flowflow record PPPOE description record to monitor network traffic match ipv4 protocol match ipv4 source address match ipv4 destination address collect flow direction collect counter bytes collect timestamp absolute monitoring-interval startflow exporter EXPORT description PPPOE Netflow destination 155.1.15.5 source Loopback10 transport udp 9995 template data timeout 86400 option sampler-table timeout 86400 option metadata-version-table timeout 86400flow monitor PPPOE exporter EXPORT cache timeout inactive 1 cache type synchronized cache entries 2000000 record PPPOE
I am using this version:
asr1001x-universalk9.03.13.03.S.154-3.S3-ext.SPA.bin
3- From another point of view, Did any service provider do this and replace RADIUS(at least for accounting) with Netflow?
Is there any benefit in this change?
Thank you
Peyman...
