Resolve duplicate flows
If your devices are configured to export NetFlow on both ingress and egress interfaces, you might see duplicate traffic in your widgets.
Duplicate flows can occur in the following cases:
- You have both
ip flow ingress
andip flow egress
applied for all interfaces on a device. - You have set
ip flow ingress
on some interfaces andip flow egress
on other interfaces. - On your serial interfaces with subinterfaces, you have NetFlow export enabled on both the physical and logical interfaces.
Things to check
- If your device configuration contains both
ip flow ingress
andip flow egress
commands, make sure NetFlow is enabled only for ingress interfaces. Go to appropriate devices and make sure the configuration contains only theip flow ingress
command. - If you have NetFlow enabled for both physical and logical subinterfaces, remove the NetFlow export commands from the physical serial interfaces and only have the subinterfaces enabled for the export.
