High link error rate?
At work I have 2 identical rooms of 24 machines.... each has its own 3com Superstack 3300 Switch with fibre module. These are then connected back to the main cabinet & then into the servers... so basically they are identical setups with approximately equal usage.
If I check the reports on each switch they are significantly different. Switch 1 shows nothing out of the ordinary & all looks good. However Switch 2 regularly reports "Link error rate high" & "Collision rate is high" on the fibre port connecting it back to the main cabinet.
So..... is this a major problem & any ideas what could be the problem?
I am off to google for some info.... but any help appreciated.

OK... well my initial suspicions are that~
A) The line is running at half-duplex
B) The fibre is running at full-duplex but is to long
Any ideas?I dreamt that a large eagle circled the room three times and then got into bed with me and took all the blankets.

Cabling problem is my first suspicion.
Any chance the suspect fiber line has been bent in too small of radius (less than 1" I believe) ?

I would hope the fibre is ok... was professionally installed some time ago & is all armoured & underground. However if it is the fibre its going to be a nightmare to check (for the same reason).
I will swap the switch gear onto a spare core & see if it still does it.. thanks for the idea.I dreamt that a large eagle circled the room three times and then got into bed with me and took all the blankets.

I would say either bad cable or a faulty module.......

Thanks for the ideas... I got it sorted now
As I suspected, who ever installed the line put a half duplex device on one end & full duplex on the other
anyway.. thanks again.I dreamt that a large eagle circled the room three times and then got into bed with me and took all the blankets.
