    Vlan vs Interfaces


      I am just now trying to wrap my head around NTA. It appears we are getting flows from almost all our vlans. This seems like ALOT of flows.  After watching the NTP 1 video they said pick most expensive links, internet connections at 1st. Start small and work your way up. So should i turn off the flows on all the vlans and hit better interfaces or is the setup with all the vlans proper?

          From my perspective, this just depends on what's important to you.  If you need to narrow down what physical port certain traffic types are traveling across, narrowing the traffic to a specific VLAN doesn't always give you that answer.  This could limit you when you are troubleshooting an issue.  If you are strictly using this for usage reporting, then it's a great way to save on the number of interfaces you need to enable Netflow for though.
