Re: [7600] Netflow doesn't export packet

Hello @ปลาวาฬทราย RMUTT CPE IX ,

the line below the 0 packets exported says :

1233 export packets were dropped due to no fib

 

is your destination in a VRF ? if it is you need to specify it using vrf <vrf-name> in the ip flow exporter configuration.

 

Edit:

I haven't seen the spoiler section the collector is in VRF and you have configured it.

 

try to verify if you have a route and a FIB entry in VRF management for the flow collector IP subnet/iP address.

 

 

 

Hope to help

Giuseppe

I can ping to the flow collector normally.
