About FSPF Link Cost
FSPF tracks the state of links on all switches in the fabric, associates a cost with each link in its database,
and then chooses the path with a minimal cost. The cost associated with an interface can be
administratively changed to implement the FSPF route selection. The integer value to specify cost can
range from 1 to 65,535. The default cost for 1 Gbps is 1000 and for 2 Gbps is 500.
Configuring FSPF Link Cost
To configure FSPF link cost using Fabric Manager, perform this task:
Step 1 In the Physical Attributes pane, expand Switches > Interfaces, and then choose FC Physical.
You see the interface configuration in the Information pane.
Step 2 Click the FSPF tab.
You see the FSPF interface configuration in the Information pane as shown in Figure 18-4.

Step 3
Double-click in the Cost field of a switch and change the value.
Step 4 Click Apply Changes to save these changes, or click Undo Changes to discard any unsaved changes.
About Hello Time Intervals
You can set the FSPF Hello time interval to specify the interval between the periodic hello messages sent
to verify the health of the link. The integer value can range from 1 to 65,535 seconds.
Note This value must be the same in the ports at both ends of the ISL.
