Configure fabric parameters

f. At the Zone Flexpars: Isolate Fabric RSCNs on zone activation
changes field, check (enable) or uncheck (disable) the
parameter. When enabled, zone FlexPars isolate and prevent
fabric-format RSCNs from propagating to devices in zones
that are not impacted.
g. At the Preferred Domain ID field, type a value between 1
through 31. This value uniquely identifies each fabric element.
NOTE: An ISL between fabric elements with identical domain IDs
segments and prevents communication.
h. At the ISL FSPF Cost Configuration field, select By Port Speed or
Ignore Port Speed to calculate fabric shortest path first (FSPF)
cost.
• By Port Speed - The fastest fabric path is determined by
port (ISL) speed. Cost is inversely proportional to speed.
• Ignore Port Speed - ISL speed is ignored, and the fastest
fabric path is determined by the number of hops. Cost is
directly proportional to hop count.
