Hello,
I'm currently trying to configure netflow on my core switch, so that I can figure out why I'm getting millions of dropped packets on a few interfaces. I'm stuck at the step where I need to provide a source interface (see in bold below). I don't think I have a loopback interface on my switch, and I'm not really sure what interface I need to select for this. I've also attached the status of all the ports on the switch if that's any use.
flow record NTARecord
match ipv4 source address
match ipv4 destination address
match ipv4 protocol
match transport source-port
match transport destination-port
match ipv4 tos
match interface input
collect interface output
collect counter bytes long
collect counter packets long
collect timestamp absolute first
collect timestamp absolute last
flow exporter NTAExporter
destination 10.10.0.1
source {LOOPBACK_INTERFACE_NAME}
