Monitor bandwidth statistics by protocol inside the IPSEC VPN on Cisco ASA

Posted on 2011-09-19
Last Modified: 2012-05-12
I have a CIsco ASA 5510 with 5 IPSEC VPNs.
Could it be possible to monitor bandwidth statistics by protocol inside the IPSEC VPN on Cisco ASA 5510?
I have to know the traffic use inside the VPN IPSEC TUNNEL.
After that, I will apply traffic reservation on the wan link.

Best regards,

I think you'll need to monitor the traffic before it goes in to the tunnel (using source destination), otherwise it's not possible. Well it is possible using specific appliances that cost a fortune and I think you don't want that.

So that being said, you could use for example PRTG in combination with netflow to monitor: http://www.paessler.com/knowledgebase/en/topic/1423-how-to-monitor-cisco-asa-firewalls-using-netflow-9-and-prtg
