asr1000 nat logging

 

Show flow monitor exporter statistics

 

You need to use the show commands to see if the ASR thinks the traffic is leaving: What is the output of show flow exporter? I always find it’s something like “SE linux” on the collector, and this stops you from seeing it in tcpdump.

 

On my cisco asr1001x nat logging does not work.

I do not see traffic on collector with tcpdump.

I tryning soft:
