HOW TO FILTRATE OUTPUT OF SHOW IP CACHE FLOW COMMAND AT ROUTER CISCO?

Good afternoon.

 

I wan to filtrate the output of show ip cache flow command at cisco router to show the "Pkts column" but in descending order so we can find quickly the conversation with highest flow?

 

The next example shot a normal show ip cache flow output:

The result that we want is the same but with Pkts Column in descending order.

 

Thanking you in advance.

Hi, I believe configuring

Hi,

 

I believe configuring NetFlow top-talkers feature would be the easiest way?

See http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/netflow/configuration/12-4t/nf-12-4t-book/cfg-nflow-top-talk.html#GUID-824723EE-2551-4D64-9E0B-F5DF065C83B9

for details.

 

Best regards,
