Hi.
Two C9300 switches are in use with HSRP configuration.
Netflow in/out is set for uplink of Act switch and uplink of Std switch as follows.
I checked the in/out traffic flow on the Act switch.
And I only checked out traffic on Std switch.
Although there is input traffic of Std switch, netflow counter does not increase.
It does not work even after generating and checking traffic such as ICMP and SSH for the Std uplink interface.
I checked the output below as a result of the "show flow monitor netflow_monitor_in cache format table" command.
There are no cache entries to display.
Error when attempting to display distributed flows << what mean?
I see it for the first time.
"Error when~"
What is the cause?
Both Act/Std switches are using the same netflow config.
There is no problem with ip cef and ip routing.
Please help.
Thanks
