Activity light flashes every 2 seconds or so on my switches
-
Quick easy question (I hope). I have several switches around my house so there is a switch in most rooms. Since installing PFsense all my switches activity lights will flash every two seconds anywhere a network cable is connected. Even if No Pc is turned on ( I think).
I did a search of the faq and mailing lists but didn't find anything.
It's not really bothering me I am just curious as to what setting is causing this and why it is doing it.

get ethereal on one of your computers and let it packet sniff for a while, then see if you can come up with some correlation. It's probably just broadcast traffic :)

Hello,
I noticed this too…
I wonder what it is...
I might play a bit with etereal ;-)

Cool, not the only person then. I haven't had a chance to play with ethereal yet had other problems I havn't been able to solve yet. Let me know if you find anything, I will try have a play tonight.

I did a fresh install of .94 and it seems to have stopped whatever activity was causing this. The only option I can think of was some option that could make finding otherpeople on my lan almost instant rather than a few seconds wait. I can't remember the name of the option and didn't find it again "yet" I will have another look for it tonight, and see if it is enabled.

Hi there,
Did you ever figure out the problem? My switch lights are also flashing every second or two.
Let us know… thanks!

Any chance you have CARP configured? With CARP the machines are sending out "Hey, I'm still alive" broadcasts so other clustermembers know about the availablility.

Its not PFSense on my network … I also have a Linksys WRT54GS which is flashed with a 3rd party firmware called DDWRT and used as a wireless access point.
It turns out that my 2 second flashes are caused by something called STP or Spanning Tree Prototcal. The fix for me was easy, I just disabled STP on my WRT54GS and voila, no more flashes.
I should say, Ethereal was key to locating the issue... I had never seen a STP packet before... interesting! :)
Thanks all!

pfSense supports STP as well if used with bridgeconfiguration. Somebody of you are using it as Bridge?

I don't think I had CARP enabled perhaps I did or had an option like that enabled. Is carp enabled by default? When I went to the page that allows you to configure carp nothing is ticked, but when I go to carp status it shows three nodes and there is a button "disable CARP" no other info.
And yeh I don't have the 2 second blinking anymore.

CARP ip's are added under Virtual IP's. They WILL make your switch port blink every second, its a heartbeat.
