We have recently upgraded all our WAN router to Cisco 3945, they all have the same FLOW config as below
but when I do a sh flow export statistics
on some routers I get:
Flow Exporter Export-FNF-Plixer:
Packet send statistics (last cleared 1d08h ago):
Successfully sent: 0 (0 bytes)
Enqueued to process level: 2534452 (3484784053 bytes)
on others I get:
Flow Exporter Export-FNF-Plixer:
Packet send statistics (last cleared 14w2d ago):
Successfully sent: 16545298 (22596920223 bytes)
Enqueued to process level: 165 (223914 bytes)
as I said all the configurations are basically the same
Does anybody know what causes this difference?
Flow config:
