2960X -- Top talkers Cache is empty

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.

Other than 2960x and 3560, on which layer 3 switch can i configure top talker for testing ??

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