I have Neflow installed and collecting data from a Cisco 877 DSL router. The interfaces I get displayed are dialer 1, VLAN1 and Virtual-Access2.
I thought dialer 1 would be the best one to use to monitor the VPN I have running but the data I would expect doesn't make much sense and neither does VLAN1. However when I use Virtual-Access2 the data seems right, what is Virtual-Access2? Is it the ATM 0?
I also have Nbar running.
What should be the correct interface to monitor on a Cisco 877 DSL router in VPN mode?
Many thanks for you time and help
