Configuring FSPF for a Specific Interface

Configuring FSPF Interfaces

To configure FSPF interfaces, perform the following steps:
Step 1 From the Fabric Manager, choose FC > FSPF on the menu tree and click the Interfaces tab.
To configure FSPF interfaces from the Device Manager, choose FC > FSPF and click the Interfaces tab.
Configure the attributes for the FSPF interfaces.
Step 2

Computing Route 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 seconds. The default cost for 1Gbps is 1000 and 2Gbps is 500 seconds

Specifying 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.
This value must be the same in the ports at both ends of the ISL.

Specifying Dead Intervals

You can set the FSPF dead time interval to specify the maximum interval for which a hello message must
be received before the neighbor is considered lost and removed from the database. The integer value can
range from 1 to 65,535 seconds.
This value must be the same in the ports at both ends of the ISL.
An error is reported at the command prompt if the configured dead time interval is less than the Hello
Caution
time interval.

Disabling FSPF for Specific Interfaces

You can disable the FSPF protocol for selected interfaces. By default, FSPF is enabled on all E ports and
TE ports. This default can be disabled by setting the interface as passive.
FSPF must be enabled at both ends of the interface for the protocol to work.

Retransmitting Intervals

You can specify the time after which an unacknowledged link state update should be transmitted on the
interface. The integer value to specify retransmit intervals can range from 1 to 65,535 seconds.
