From the Administration Console and the Web Management interface, you can display general statistics for specific OSPF interfaces. These statistics provide valuable information useful in troubleshooting network and system issues. For example, the number of SPF computations directly corresponds to the number of topological changes that the interface had to converge on. An excessive number of soft restarts may be an indication that the router is overburdened because of resource limitations. OSPF statistics:

• SPF computations - Number of shortest-path-first computations made. Each time that a router comes online, or each time there is a change in topology, the router must perform SPF computations.

• Memory failures - Number of nonfatal memory allocation failures.

• LSAs transmitted - Number of link state advertisements transmitted.

• LSAs received - Number of link state advertisements received.

• Route update errors - Number of nonfatal routing table update failures.

• Receive errors - Number of general receive errors.

• External LSA changes - Number of external LSA changes made to database.

• Soft restarts - Number of OSPF router soft restarts due to insufficient memory resources (implies a fatal memory allocation failure). To fix this problem, change the OSPF memory partition with the ip ospf partition modify option, add memory, or reconfigure the network topology to generate smaller OSPF databases.
