Open source network management software

I have a collection of Catalyst 4948s for which I have a general purpose Linux box I have used to span traffic to for subsequent analysis using wireshark.

I currently use Cacti for traffic graphing but that application does not provide the visibility into the protocols which comprise a graphed traffic pattern.

Is there an open source package available which can be run on the same Linux platform which in real-time could analyse traffic spanned to the same server?

My objective is to gain a better understanding of the behavior of hte traffic I am supporting on my Catalyst switches.

Thanks in advance for any insights possible on this.

Re: Open source network management software

There are several open-source NetFlow collectors. I would recommend doing some research on NetFlow and using it to better understand the traffic running in your environment.

The 4948 supports it quite well.

Cheers,

Tim
