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, perform this task:
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.
Configuring Hello Time Intervals
To configure the FSPF Hello time interval, perform this task:
Command Purpose

configured, enters configuration mode for the
specified interface.
Step 3
switch(config-if)# fspf cost value vsan
vsan-id
