I wanted to see if I could buy some cheap USB NICs and use those instead of my Quad NICS, Here’s what I bought: These USB NICs from Dealextreme cost $4.80 a piece at the moment and I bought 12 of them. You also need a motherboard that supports 3x PCI slots so most people end up buying a seperate “GNS3 Server” for the Quad NIC solution. The downside of this card is that you’ll find them for $150 – $200 on Ebay and for the CCIE lab you’ll need 3 of them. The quad NIC solution works very well and as a result many people are looking for the D-Link DFE-580TX card that is working very well. I spent more time fixing the breakout switch than doing actual labs. Ports going into err-disabled mode without really understanding why, MAC addresses flapping and other nasty stuff.
