I thought what i was saying was complete nonsense i knew that we would run seperate fibre links for c2k and legacy.

but if your cabinet 2 is not getting access to the internet does this then affect your c2k computers it may just be the fibre link for your legacy switch which is the problem.

Actually Stephen, we do indeed have a switch that has half its ports as c2k and half its ports as legacy and shares fibre from its cab back to cab1.  Maybe not common procedure, but you can come take a look if you want and see for yourself if you don't believe me. 

And yes, Aaron it could well be the fibre link being the problem here and its what I originally thought and pretty much still do.  But if SNAC can block network access by port or by switch, surely they could block a legacy switch which, after all, is simply another subnet of the c2k WAN?  Its just supposition of course, but it's bound to be possible in theory.

Did Northgate configure the switch this way for you?

if it is i would get straight on the phone and get it changed legacy and c2k are always ment to be kept seperate not shared in anyway. Other than the internet thats the only share we are supposed to have, also i would have thought that this woudl have cause major problems with either of the two networks if you were sharing a switch.

lol I did it myself.  Shhhhh.


Yep they did actually.  You reckon I could sell tours to view this magical thing that is both a c2k and a legacy switch?

@Aaron :  The switch is partitioned logically so there is no crossover between the networks.  Why should I demand it be removed?

WOW Never thought C2k would let you use even part of any of their switches as a legacy!!!!!! Even though it is possible.

Is this official procedure, like could you fill in a form to get it done? I would be very interested in getting it done here maybe. Or was it done as a pilot? Or was it done under the table by a friendly northgate technician?

It was all done above board! It was the only viable way of getting more computers on the network without ripping up tarmac (the cab in question is off the main building).  They probably don't do this too much all the same. :)

Do they support it, if none of the stations worked when using that switch, but did work when using a legacy switch will they try to fix it?

if you had a legacy switch out in the cab could you not piggy back off it onto another legacy switch instead of using a c2k switch?

They support the c2k machines there, and yes, they would support the switch if it fell over, but thats it. Anything to do with the legacy would be my problem unless it was their switch at fault I guess.

That was the problem Aaron there was no legacy switch in that cab and the teacher there wanted his stand alones he had there to have internet access.  That particular cabinet had no legacy support at that time.

Just a quick update:

It seems like the ethernet convertor is the problem after all.  Going to try to source one off Ebay if I can.

if you need to change the switch do you think c2k will reconfig it again for you ? just if it was easier to change the switch than source the convertor
