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
