When I change IP addresses on my 'em' gigabit NIC, ARP isn't sent properly. This appears to be the problem in the following bug report, however i'm using the 'fixed' version of the em driver (in FreeBSD 4.9). http://www.freebsd.org/cgi/query-pr.cgi?pr=54488 Does anyone have any tips on how to get around this? I'm building new systems with gigabit ethernet support and this problem keeps cropping up. I have a failover system, and when moving an IP alias between machines, the em NIC driver doesn't properly send out gratituous ARP, resulting in the IP being inaccessible. - The problem does not occur when plugged into a 100BaseTX switch - FreeBSD 4.9p1 / em version 1.7.16 - Tried various gigabit switches. - One other odd thing is that when configuring the NIC (ifconfig) the machine locks up for several seconds. Thanks in advance. Nate
