how many 5m XRN cables can hold the stack ?

we are running many XRN fabrics, and one of them 3 cables of 5m



 



 



5500G-EI <---- very long distance----> couple of 5500G-EI <--------very long distance ----> 5500G-EI



 



 



 



XRN doesn't work (it is split to 2 separate fabrics), the diagnostic is:



 



<5500G-EI>display ftm information


FTM State       : HB STATE


Unit ID         : 2 (FTM-Slave)





Fabric Type     : Line


Fabric Auth     : NONE


Left Port       : Isolated (connection error)


Right Port      : Normal





Advertise       : Send = 24, Receive = 51


Advertise ACK   : Send = 46, Receive = 3


Heart Beat      : Send = 0, Receive = 71


Left Check      : Send = 5474, Receive = 183


Right Check     : Send = 527930, Receive = 527421


Auto update     : Send = 0, Receive = 0





Left Port       : Index = 7, IsEdge = 0


Right Port      : Index = 5, IsEdge = 0

You display FTMs of two switches. Which two of four are they exactly?

well, I configured IP address for the fabric itself (for both fabrics), connected to that address and typed a command.

well, as it shows me "unit 2 login" and "unit 4 login", so



 



 



 



unit1 <----- 5m ------>   (unit2 + unit5) <----- 5m-------> unit4



 



I'm not sure about order, it could be either unit2 ---- unit 5 or unit5 ---- unit2



 



 



unit5 beleives it is a separate fabric (of single unit).
