Dear Elite Team,
can a fabric be formed with any two Brocade switches running any different FOS versions?
or is there a particular document which explains this compatibility..
please let me know your thoughts and appreciate your pointers.
yes, you can ISL switches no matter if the Modell or FOS is different as soon this are supported and compatible.
for details refer the FOS release Notes, or post here exact Switches Type / Model and exact FOS Releases
example from FOS 8.1.2a Release Notes
for those Switch Models
Brocade DCX, DCX-4S, 300, 5100, 5300
FOS v7.3.1 or later is required to Interoperate to FOS 8.1
BTW. for privacy, you should don't post Phone Number in the community, but is you own decision.....
