i've tried this on one our 1941 but i'm getting an error. do you know what i'm missing?
1941(config)#ip flow-top-talkers
1941(config-flow-top-talkers)#sort-by bytes
1941(config-flow-top-talkers)#cache-timeout 60000
1941(config-flow-top-talkers)#exit
1941(config)#int g0/1
1941(config-if)#ip flow ingress
1941(config-if)#ip route-cache
1941(config-if)#do show ip flow top

Hi John,
Did you configure "top 200" command on 1941?
Kind Regards,
Ivan

Hi Ivan,
Is it supported on 3500 or 3750 ?

Hi Prashant,
3750 and 3560 switches do not support netflow, but there is a service module which can be inserted into 3750X and this supports Flexible Netflow (FNF). The commands are available but will not work unless the module is installed.

The netflow support matrix can be seen in table 1 here:
Kind Regards,
Ivan
