b. At the Rerouting Delay field, check (enable) or uncheck the
parameter. When enabled, traffic is delayed through the fabric
by the error detect time out value (E_D_TOV). This delay
ensures Fibre Channel frames are delivered to their
destination in order.
c. At the Domain RSCN field, check (enable) or uncheck the
parameter. When enabled, attached devices can register to
receive notification when other devices change state.
d. At the Suppress RSCN on Zone Set Activations field, check
(enable) or uncheck the parameter. When enabled, RSCNs are
not transmitted when a zone set is activated.
e. At the Limited Fabric RSCN field, check (enable) or uncheck the
parameter. When enabled, RSCNs are not transmitted after a
director initial program load (IPL).
f. At the Zone Flexpars field, check (enable) or uncheck the
parameter. When enabled, zone FlexPars implement an
isolation feature that prevents 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 Default or Equal.
to calculate fabric shortest path first (FSPF) cost.
• By Port Speed - The fastest fabric path is determined by
port (ISL) speed. FSPF cost is inversely proportional to ISL
speed.
• Ignore Port Speed - ISL speed is ignored, and the fastest
fabric path is determined by the number of hops. FSPF cost
is directly proportional to hop count.
