Port shows No_Sync on Brocade 200 (option to disable/enable port to refresh?)

[ Edited ]

My MPX FC switch in Brocade200 port is showing as No_Sync.

How to determine where the issue is - whether faulty cable, SFP or something else? Would I be able to disable and renable the port on the Brocade to test and perhaps "refresh" the connection?

Re: Port shows No_Sync on Brocade 200 (option to disable/enable port to refresh?)

No_sync most likely means that ports can't negotiate the speed of the connection. Did you already check the speed settings on both sides?
