Statistics counters :
Number of packets received : LSU
Number of packets transmitted : LSU
Number of times inactivity timer expired for the interface = 0
This displays the number of packets; Hellos should be received every 20 seconds.
FSPF routing is active.
1.
The cost of the path out this interface.
2.
3. The configured FSPF timers for this interface, which must match on both sides.
4. Either Full State or Adjacent. Sent and received all database exchanges and required Acks. Port is
now ready to route frames.
5. FSPF neighbor information.
Step 3 Use the show fspf internal route vsan command to verify that all Fibre Channel routes are available.

This shows the total cost of all links.
The next hop (238) has two interfaces. This indicates that both paths will be used during load sharing.
Up to sixteen paths can be used by FSPF with a Cisco MDS 9000 Family switch.
With the implementation of VSANs used with Cisco MDS 9000 Family switches, a separate instance of
FSPF runs within each VSAN, and each instance is independent of the others. For this reason, FSPF
issues affecting one VSAN have no effect on FSPF running in other VSANs.
Note For all FSPF configuration statements and diagnostic commands, if the vsan keyword is not specified,
VSAN 1 is used by default. When making configuration changes or issuing diagnostic commands in a
multi-VSAN environment, be sure to explicitly specify the target VSAN by including the vsan keyword
in the statement or command
OL-9285-05
To issue commands with the internal keyword, you must have an account that is a member of
the network-admin group.
