Re: Link UP/DOWN problem with re0 on FreeBSD 7.1
FreeBSD a écrit : Hi everyone, Just to put you in context, I applied the following patch to make the card available: SVN rev 186389 on 2008-12-22 00:46:22Z by yongari Since we don't request reset for rlphy(4), the link state 'UP' event from mii(4) may not be delivered if valid link was already established. To address the issue, check current link state after driving MII_TICK. This should fix a regression introduced in r185753 on fast ethernet controllers. --- I don't have any issue related to that anymore. The problem is that I get link UP/DOWN a few times per hour on 3 identical machines that I dumped/restored. They are all pluged in a Cisco switch that works fine for every other PCs.

I just tried to download a big file (FreeBSD 7.1-REL DVD iso in fact) to see if the deconnection occurs even during a transfer. The DVD downloaded successfully and I verified that the MD5 are OK. BUT, /var/log/messages continue to tell me that: Feb 4 16:09:29 term003 kernel: re0: link state changed to UP Feb 4 16:19:26 term003 kernel: re0: link state changed to DOWN Feb 4 16:19:30 term003 kernel: re0: link state changed to UP Feb 4 16:19:32 term003 kernel: re0: link state changed to DOWN during the transfer (which worked OK). I don't know if that can help someone to help me ;) Thanks, Martin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org" I have a solution to this well a work around. Add -tso to the relevant line in /etc/rc.conf ifconfig_re0="inet 192.168.1.103 netmask 255.255.255.0 -tso" Adding -tso stops the link up / link down problem. Now I am understand that this may increase cpu if the traffic on the nic is high. I am sure some one the list will know of any other implications this may have. It is a known problem and I site I read the bug had been submitted so hopefully it wont exist in 8.0 Regards Graeme As I stated in my last post, I tried to disable a few options, including TSO. Still, I gived a try to your workaround. I now have this line in rc.conf: ifconfig_re0="DHCP -tso" but I have the same problem (it disconnect every 10 minutes and ask for an IP to the DHCP). Thanks for your suggestion, Martin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org" I don't use DHCP so it never causes me a problem, have you considered setting a static IP address ?
