That's bad. :( > My os is fedora 5 ,nic is realtek 8039, any hints is appreciated. It should just work<tm>. Have you already tested the NICs in A and B? One good way is to connect A and B with a crossover cable, remove the vlan config from A and try to communicate. Another thing to try for this problem is to sniff the connections between A and switch, and between switch and B, using a separate computer and preferably a hub to really see what gets sent on the wire. > Also, will who succeeded with setup 1b tell me your linux os > version and nic type? > I will try redhat 9 and intel 82559 nic as soon as possible. Fedora should work just as well as RH9, but trying the Intel NICs is a good idea. Make sure you use the e100 driver and not the eepro100 driver though. Only e100 supports VLANs out of the box. I've gotten the setup to work using various Linux versions (Slackware, Gentoo, self-built) and Intel NICs as well as 3Com NICs, but I think the 3Com driver still needs a patch so watch out for that. Try Intel first if you can. :) //Peter _______________________________________________ Vlan mailing list Vlan@xxxxxxxxxxxxxxx http://www.candelatech.com/mailman/listinfo/vlan
