Hi, I have a network and I use a 5 procurve switchs for all 3 floors. 2 switches are in the server room on the 3rd floor. From the 3rd floor and a link goes to the 5th floor switch and from there a 2 link come down to the 4th floor to 2 switches.
Mostly every morning all of my switches stops working, the cables are fine, everything looks fine in the switch but nobody can see nobody in the network but when I unplug the switch from the power supply or unplug the network cable (Link) and plug it again, everything gets normal, the problem is solved and the network becomes fine again. I dont have any idea of what could it be, maybe is not even the switch. I checked the logs and saw high collision error. We have two 10 base hub which we have configured the switch port from 100 to 10 Auto. We are changing the two hubs with gigabit switches.
I am not sure, where to begin to diagnose whats going.
Any help will be greatly appreciated.
