Great, I'm investigating how to turn the sflow stuff on right now, and once I get that done, I'm gonna look at getting that set up

Luca has made some really nice changes in the latest version of the sFlow plugin and has even better stuff in mind for the future. Ntop is well on its way to being a kick-butt sFlow collector/analyzer. Luca rulez! ;-) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bret Jordan Sent: Wednesday, October 13, 2004 9:41 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: [Ntop] Question (probably dumb) from a new user Yes your FastIrons and BigIrons, things based on their JetCore ASIC do support this. Foundry has started outsourcing some of their "edge" devices and I am not sure if the EdgeIron have this support. But I believe they use the same chipset (broadcom) as the HP 2800 series. And if that is the case, then the chipset does support it and Foundry has probably turned it on in their software. Another thing to think about when you are doing this is what kind of VLANs do you have. If you put a hub before the router or port mirror a port some where in your network, that does not mean you will get all the traffic as you will only see the layer 2 traffic that needs to go across that link. If the traffic is internal to some VLAN then you might not pick it up. Foundry does support SFLOW, which is really cool BTW. So you can setup a box (NTOP) as an SFLOW collector and tell all your switches to send samples of all packets to the collector. This will give you a good idea of what is going on in your network everywhere, regardless of where you put the NTOP box and what VLANs you have. I would really use the CVS version of NTOP though if you are going to use SFLOW. Luca made some really nice changes to the SFLOW plugin, but it is still a CVS only kind of thing. Another thing, do not try to run NTOP with SFLOW on AMD Opterons. It does not work. I am trying to get a box setup for Luca to test on so that we can get this working.
