Yesterday, I was setting up some switches that were configured with multiple VLANs. It made me wonder if it's possible to configure a NIC to be part of a VLAN, instead of requiring a switch port to be configured for that VLAN. If so, the computer could be plugged into any available trunk port, rather than a specific VLAN port. -- Use OpenOffice.org http://www.openoffice.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

So, I guess it would require recompiling the kernel to add VLAN support. A VLAN is simply a means of using an ethernet switch on mulitple LANs without interference. On the network I was working on yesterday, they've got a combined data and voice system, with both coming down the same wire. Apparently the phones are supposed to apply the correct tags to the phone and data traffic. On this job, there were 5 switches with 24 - 100 Mb PoE ports and 2 gigabit ports. One of those switches also had built in router functions. And there was also a 24 port gigabit switch, used to stack the other 5 and for servers. Most of the ports were trunks, but the router switch had one configured on VLAN 1, for internet access and the gigabit switch had 5 trunk ports, for stacking and a mixture of VLAN 1 ports for servers and VLAN 2 for VoIP. I also placed a VLAN 3 port on the router switch, for the management interface. Lots of fun, getting all that configured. ;-) -- Use OpenOffice.org http://www.openoffice.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Nah, the vendor kernels all include vlan support already. Joe -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Joe I'll have to look into that sometime.

From what I remember last time I looked into it, only certain network cards had the capability to implement the vlan functionality. The intel e100/1000 had it as I recall. Joe -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

For vlan you need iproute2. For example: vconfig add eth2 300 -- creat interface eth2.300 with VID 300 on eth2 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
