Hello Guys ,
I am trying to configure ISL between 2 sites over Multiplexer .
The Distance is 10 KG .
I have checked the FOS compatability and over paramertes .
Is there any way on how to configure the port or using the SFP types (LW or SW)
Within the Fabric OS Administrator guide there is a chapter (Managing Long Distance Fabrics) that talks about this. On the other hand, the use of a LW or SW SFPs is stablished by the xWDM/TDM device.
since you want to create ISL trough "Multiplexer" i assuming you meaning any WDM technology, CWDM or DWDM no matter, you need just to ISL the both switch with the WDM.
Switches must have same SFP Characteristics as the SFP inserted in WDM, Shortwave or Longwave.
Additional, this is my experience, you should set the Switch Port Speed Fixed as the Speed Port in WDM.
