Is there any way to avoid that scenario - ie, when you break >an interface, have it be really broken, down, unpingable? For many of the ethernet interfaces, there isn't any indication that the link is down. On the other hand, for the 100Mbps interfaces, it is possible in some cases to get an interrupt from the PHY of the link status change. We don't currently do anything with that, however. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project - http://www.freebsd.org Creator of high-performance Internet servers - http://www.terasolutions.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
