580CHAPTER 19: OPEN SHORTEST PATH FIRST (OSPF)

Field

Description

 

 

receiveLSU

Number of link state update packets that have been received

transmitDD

Number of database description packets that were transmitted

 

Interpretation:

 

A non-zero value is OK.

 

Database description packets are sent when forming

 

adjacencies with valid neighbors. A large number in a

 

network whose configuration has not changed could

 

indicate that adjacencies are being torn down and

 

re-established.

 

This statistic is incremented under the following circumstances:

 

When an OSPF database descriptor packet is transmitted.

transmitError

Number of general transmit errors

 

Interpretation:

 

A non-zero value indicates that an OSPF packet could not be

 

sent either out a particular interface, or to a particular

 

destination. This could prevent OSPF from running properly

 

within the autonomous system and lead to routing

 

problems.

 

This statistic is incremented under the following circumstances:

 

When an OSPF Hello, LSU, or LSAck is being sent as a

 

multicast packet on a non-broadcast multiple access

 

network.

transmitHello

Number of Hello packets that have been transmitted

transmitLsAck

Number of LSA acknowledgments that have been transmitted

transmitLSR

Number of LSA request packets that have been transmitted

transmitLSU

Number of link state update packets that have been

 

transmitted
