Hello folks:
I have a cisco ISR and I configured Netflowv9 on it successfully. I am collecting the data on my Netflow collector without any problems.
However, I am not getting any return to some of my show commands on Cisco ISR router:
isr4300-3977#show ip cache verbose flow

What am I missing? I entered "ip route-cache cef" command under the interface just in case it is required for this command to work. That did not help. To be honest, I did not need "ip route-cache cef" to enable Netflow on this ISR router.
Are these commands not supported on this platform?
Thanks

Correct command as below :
show ip flow top-talkers
HO2#show ip flow ?
export Display export statistics
interface Display flow configuration on Interfaces
top-talkers Display top talkers

That didn't work for me. Should I be enabling something on the router?
