Repeating link state UP/DOWN atleast 5 times an hour (log entries inside)
-
OK bummer. I have an asus switch that people complain about issues with certain nics/equipment due to power management so fig'd worth asking. :)
Perhaps try without powerd or different type nic or different cables perhaps. Otherwise if you don't lose connection it might not be a big deal. :D

fyi….all ports show ZERO up/down states when connected to different tools.
...so i dont think its the switch. i am wondering if powerD is powering down the NIC and causing for the up/down state. powerD shouldnt do that should it?
-
i have also turned off all 'off-loading' on the cards. ….ill monitor it over the next 24 hours to see...but all the NIC's are the exact same model of netgear 1gbps NIC (i dont know the model number off the top).

more info on this topic…
i have tried TEN different switches ....
the only thing i can think of is the NICs that might be causing this problem. i have zero problems with em0 (onboard gbic), but the other four NICs i have the problem with. Those NICs are ALL the same model/brand - d-link dge-530t
just your simple PCI gbic NIC from frys bought at 40$ a pop. i have never had a problem with these NIC's before, and on the switches i have ZERO errors..etc.
any thoughts?

I'm not sure about the sk driver but some of the Marvel NICs supported by the msk driver suffer from a fault in which it stops reveiving packets. The driver had a work around for such a condition that might cause the logs you are seeing as it resets the NIC.
This is some what speculative but both the sk and msk drivers are derived from the same source.Steve

is there a perm work around? …..or should i got with different NICs? if so...which NICs would be recommended? tks in advance
-
anyone?
-
Howdy,
Guess I'd figure if it isn't hurting anything might be safe to ignore.. Otherwise try different NIC's, research more to see if there is a fix (like replacing drivers, tweaking settings etc) or wait for an update that might fix it. Think I'd pick option #1 or #2 myself. :D

I was experiencing something similar, but the frequency was 5-10 up/down cycles per minute. I'm running a Jetway daughterboard with 3 Intel Gigabit NICs. Only the center NIC was experiencing the behavior. Reboots did not help, but leaving the machine unplugged for 15 minutes did.

Hey ResIpsa,
I'm using jetway mb & 3 port intel gbit nic daughterboard & haven't seen that. Maybe I need to look closer.. Odd unplugging it for 15 minutes made a difference but maybe one of life's mysteries. :D Imagine there is some logical explanation though.

i upgraded to the latest snapshot from flat RC3 and it seems to have fixed it. however, it did screw my snort all up.

Mine is back - it looks like it is doing it every couple of minutes:

Sep 5 09:12:09 php: : Hotplug event detected for opt2 but ignoring since interface is configured with static IP (172.30.1.1)I'm running 2.0-RC3 (i386), built on Fri Sep 2 14:17:09 EDT 2011.

yes…i noticed mine doing it again. i switched out NICs to make sure that wasnt it.
i am going to update this weekend after i do a switch over
