I want to save the details of the network traffic by my Cisco Switch [source IP, dest, protocol...]. Is it possible to enable logging to capture the details of the network traffic by my Cisco in a Syslog Server? If Yes, how can I do it ? o_O

Hope someone will understand my problem
Thanks in advance :)


There's a protocol created by Cisco for this very purpose: netflow.

You have to check if your version of IOS support it, and you need a netflow collector that will receive and record the information from the switch.

Cisco reference some free Netwflow software on this page but there's plenty others.

Many software provide both the syslog and the netflow functionalities, but this is two different services that address different needs.
