I know everyone's network is setup differently but I just need some help on what interfaces could be best to monitor on our Telstra (Australia) Cisco managed routers.
Telstra enabled NetFlow for us on a number of interfaces but I am not sure which ones I should select. Maybe all of them.
Some aren't enabled for NetFlow so I can ignore them but some routers have 3 interfaces available; a Dialer, VLAN and Virtual Access. Some are marked Customer LAN.
On the routers with 2 interfaces the in / out numbers kind of match each other but not sure if I need to monitor both.
Have attached a screen shot and hopefully it doesn't include any personal information.
Thanks heaps
Nathan
