Hi, I have a problem with getting vlan to work on my linux comp with a 3com 905C. Adding the vlans with vconfig isn't a problem. I've set up eth1.1 - 5 and addressed them with separate 192.168.* networks. The Cisco 3500XL is configured for trunking with dot1q on fa0/1. The problem is that when i look at the traffic in iptraf and ping the router from the switch the ICMP packets come in on eth1, not eth1.1. Same thing when setting port 0/2 on the switch to vlan 2 and connecting a computer to it. DHCP requests incoming on the unaddressed eth1 interface. it was a few years ago i got my CCNP so i dont remember how to check trunk negotiation. Show interfaces fa 0/1 dont give me any clues to if the trunk works or not. Thanks in advance, Magnus Ternstr?m -------------- next part -------------- An HTML attachment was scrubbed...
