Greg I just turned on nbar(ip nbar protocol-discovery) on all my router interfaces, I Im running a 2600 with 2Serial T1 interfaces and 1 FastEthernet interface, I currently graph cpu utilization, so I will let it run for a day and report back the cpu statistics.

What is the router overhead? It's got to be high if it's doing payload inspection. I want to see a pre and post implementation router-cpu graph. -- Attached file removed by Ecartis and put at URL below -- -- Type: application/ms-tnef -- Size: 1k (1875 bytes) -- URL : http://www.ee.ethz.ch/~slist/p/70-WINMAIL.DAT -- Unsubscribe mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/mrtg FAQ http://faq.mrtg.org Homepage http://www.mrtg.org WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi -- Unsubscribe mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/mrtg FAQ http://faq.mrtg.org Homepage http://www.mrtg.org WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
