Fields in the IP OSPF Interface Statistics Display

Field

Description

 

 

adjacencyDown

Number of times that OSPF adjacencies have gone down

adjacencyUp

Number of times that OSPF adjacencies have been formed

authError

Number of packets discarded due to OSPF authentication errors

 

Interpretation:

A non-zero value is bad and means that packets from some OSPF routers are being discarded due to authentication errors.

 

This statistic is incremented under the following circumstances:

 

If the OSPF packet authentication type is something other

 

than simple password (i.e., cryptographic authentication is

 

not supported in the current implementation).

 

If the OSPF packet contains a password but the interface

 

does not have a password configured.

 

If the OSPF packet has a simple password that does not

 

match the password defined for the OSPF interface.

computeDR

Number of times that the designated router has been

 

computed

lsaXsumError

Number of LSA checksum errors that were detected

mismatchAreaID

Number of interface area ID mismatches that were detected

mismatchAreaType

Number of interface area type mismatches that were detected
