Description

Possible Values

[Default]

Virtual link

Index number of the virtual link
for which you want to display
statistics

■

Valid interface

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 (that is, 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 was computed

lsaXsumError

Number of LSA checksum errors that have been detected

mismatchAreaID

Number of interface area ID mismatches that have been
detected

mismatchAreaType Number of interface area type mismatches that have been

detected
