Hi John,


Did you configure "top 200" command on 1941?


Kind Regards,
Ivan

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:

Ivan
