Hi,
I have configured ip flow top talkers on 2960X switch like below
ip flow-top-talkers
top 10
sort by bytes
cache timeout 60000
And ingress/egress is applied to ports. But when i want to see the output...i get always CACHE IS EMPTY.
CEF is enabled. Above commands works perfectly on 871 router.
IOS version is c2960x-universalk9-mz.152-6.E1.bin
Please suggest whatelse needs to do to get it work.
Regards,
Faizan.

Honestly, I searched in the feature navigator and the full command reference for 2960X but I couldn't find the support for that commands, the 2960X only supports Netflow Lite since 15.2(2)E, you could configure it and use a collector like PRTG (free until 100 sensors) in order to see the top-talkers, top-connections and top-protocols from your connections. https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960x/software/15-2_5_e/command_reference/b_1525e_consolidated_2960x_cr/b_1525e_consolidated_2960x_cr_chapter_0101.html

Hello estimated!
Did you use this command "ip route-cache flow" in the same interfaces you are using the ip flow ingress and egress commands? Try this way and let me know If this could help you.

I think you can run the Top-talkers in a 3750 with IP Services image.
