Intrepid® 6064 Director Installation and Service Manual

Installation Tasks

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 LimitedFabricRSCNfield, 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. Thisvalue uniquely identifies eachfabric element.

NOTE: An ISL between fabric elements with identical domain IDs

segments and prevents communication.

h. Atthe ISL FSPF Cost Configurationfield, 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 pathis determined bythe number of hops. FSPF cost

is directly proportional to hop count.

3. Click OK to save and activate changes.

4. Set the director online (Setting the Director Online or Offline on

page 4-36).
