From my experiance it is definitely _not_ stable in 3.1, but I had a 3.2 Stable system running for months with 4 nics plus 6 vlans. It paniced a couple of times, but that might have been an mbuf problem. I have just come across a big problem using vlans on a FreeBSD box. The mtu on the vlan interfaces is only 1496 bytes, the problem is that any packets destined for the Interface larger than this are just thrown away. The solution to this problem seems to be to allow larger ethernet packets, or to set the mtu on all the other systems on the vlan to 1496. The second solution is not practical for some of my networks, I will be looking at this more next week. > (BTW: The VLAN support is needed for a production machine, so > running -current is not really an option.) If you can work around the above, it _should_ be fine. Tim. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
