recycling NICs from IXP12EB's, gig NICs & multiple IXP12EB's in a PC (running VERA)
Q1. I have vera working happily on an ixp12eb (rev C.), can the ethernet board that comes with the ix12eb kit be recycled into a linux box? I'm tempted to try, and did in fact do this, but the machine wasn't happy booting so I figured it could be either the ancient machine I was trying or something more fundamental in the ethernet nic that comes with the ixp12eb. Q2. I'm interested in talking to people that have used vera and the 1 Gig interfaces... anyone out there? I'm interested in using them for traffic generation, but would like to talk to anyone who has done more than the basic "turn it on" and "yep the physical layer is working" test. Q3 now this one might be a bit odd, however.... What problems are there with sticking several ixp12eb's into a machine? I assume in its current incarnation the vera drivers are not aware of several boards? (no I've not tried it) any ideas what the load is for an ixp12eb? is it going to 'cause the mobo pci supplies to be draining too much? This would be for a "lots of ports" traffic generator.... although a "lots of ports" might be good too. cheers, Andrew.

Yes, it's an ordinary 10/100 Mbit card. Red Hat Linux 7.2 had no trouble automatically identifying the board.

It may be that multiple boards will draw too much current. Since these boards were designed for a passive backplane in a prototype environment, they may not have been designed to meet every PCI spec.

Yes, they are! The driver is configured for 4 boards. If you will use more, you need to change the definition of NBOARDS in the main driver file: Runtime/linux-i386/driver/drvVera.c

No, that's the main concern. We've had as many as 3 boards in one system at one time. We regularly run systems with 2 boards. Scott
