Are there any vlans?  Or could you create them?  I'm pretty sure on a cisco switch you can mirror (span) a port to monitor a whole vlan.

Hello,

I'm having problems capturing packets with my Linux box.

The LB runs Fedora Core 4 and it's connected to the main switch with a network card. It has another network card used to capture packets.

The switch permits to configure port mirrors, but one per time: I mean, I can set a port to be mirrored to another, but not 10 ports to be mirrored to the same port.

I'm capturing traffic, but it seems all the traffic is generated by the LB except some Rarp packets.

Moreover, some traffic isn't detected at all (ex. MSN).

Any advice?

Thank you.

 

Alessandro
