Chapter 11 Troubleshooting VSANs, Domains, and FSPF FSPF Issues Send documentation comments to [email protected] Troubleshooting FSPF Using Device Manager To troubleshoot FSPF using Device Manager, follow these steps: Step 1 Step 2 Step 3 Step 4 Choose FC > Advanced > FSPF and select the LSDB LSRs tab to verify the link state records (LSRs) in the FSPF database. • The VSANId/ DomainId column shows the domain's view of the fabric topology. • The AdvDomainId column shows which domain is the owner of the LSR. • The Age value is a 16-bit counter starting at 0x0000, incremented by one for each switch during flooding and by one for each second held in the database. This field is used as a tie-breaker if incarnation numbers are the same. • The IncarnationNumber is a 32-bit value between 0x80000001 and 0x7FFFFFFF that is incremented by one each time the originating switch transmits an LSR. This is used before the Age value. Choose FC > Advanced > FSPF and select the LSDB Links tab to verify that each path is in the FSPF database. Choose FC > Advanced > FSPF and select the Interfaces tab to verify that the FSPF parameters are correct for each interface and verify that the AdminStatus is up. • The Cost column shows the cost of the path out of the interface. • The Intervals column shows the configured FSPF timers for this interface, which must match on both sides. • The State column shows the full or adjacent state if the interface has sent and received all database exchanges and required Acks. The port is now ready to route frames. • The Neighbors column shows FSPF neighbor information. Choose FC > Advanced > FSPF and select the Statistics or InterfaceStats tab to verify that there are no excessive errors present.
