Cisco – How to know if the site-to-site vpn connection is being saturated

cisconetwork-monitoringnetworkingsite-to-site-vpn

We've got a T1-internet connection with a Cisco ASA 5510 appliance in our small office.

We have a site-to-site vpn connection from our office to a remote data center.

Question(s):

  1. How can I find out if my site-to-site vpn traffic is being saturated via the Cisco ADSM?

  2. Are there other simple/free tools that can show me if my site-to-site vpn connection is being saturated?

Best Answer

I believe that the Cisco ASA 5510 has NetFlow support built into it which should supply the statistics that you're looking for. There's an article on configuring NetFlow on the ASA here.

With regards to part 2 of your question, I've had some good results using SolarWinds NetFlow Analyzer with sFlow rather than NetFlow, but the results should be similar.
