Also, it's not a problem all the time, only sometimes the boxes fail to send out Gratuitous ARP packets. I have verified by capturing packets and trying to readd an alias a short period after the failure.

My work around is to set the arp cache timeout on our 2811 router to 10 seconds. Colin David Kirchner Sent by: To owner-freebsd-sta "Marc G.

Haven't tried 6.0-STABLE (can't get -RELEASE to install due to unrelated bug bin/88872). According to cvsweb, 6.0-RELEASE has the latest Intel driver. Also: The bug you're seeing may be unrelated to the bug I was seeing, but I suspect they may be similar. Arps just don't seem to be going out like they should _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd.org"
