Hi, you can leave the Domain ID at the default.  It will make no difference to the switches or the protocol while running in a single switch fabric.  Regards, Erik
I have two new Brocade Switch 6520, acting as standalone, i wont merge those  The default domain id is 1  I want to learn about the best practices to set the domain id  for standalone switches, is there any advice to about brocade 6520 domain id must be greater o smaller than others? for example Brocade 6520-1 Set the domain to 3 and the other Brocade 6520-2 Set the domain id to 4.  Does it matter domain id ranking??   Do you recommend to use or leave the default id ? or change it just for best practices   Bes regards
