OSPF Interface Statistics
Statistic Description
exchange done
The sum total number of neighbors in this state (that is, in an adjacency's final state)
having transmitted a full sequence of Database Description packets, across all OSPF
areas and interfaces.
bad requests
The sum total number of Link State Requests which have been received for a link state
advertisement not contained in the database across all interfaces and OSPF areas.
bad sequence
The sum total number of Database Description packets which have been received that
either:
•
Has an unexpected DD sequence number
•
Unexpectedly has the init bit set
•
Has an options field differing from the last Options field received in a Database
Description packet.
Any of these conditions indicate that some error has occurred during adjacency
establishment for all OSPF areas and interfaces.
loading done
The sum total number of link state updates received for all out-of-date portions of the
database across all OSPF areas and interfaces.
n1way
The sum total number of Hello packets received from neighbors, in which this router is
not mentioned across all OSPF interfaces and areas.
rst_ad
The sum total number of times the Neighbor adjacency has been reset across all OPSF
areas and interfaces.
down
The total number of Neighboring routers down (that is, in the initial state of a neighbor
conversation) across all OSPF areas and interfaces.
OSPF Interface
Change Statistics
hello
The sum total number of Hello packets sent on all interfaces and areas.
down
The sum total number of interfaces down in all OSPF areas.
loop
The sum total of interfaces no longer connected to the attached network across all
OSPF areas and interfaces.
unloop
The sum total number of interfaces, connected to the attached network in all OSPF
areas.
wait timer
The sum total number of times the Wait Timer has been fired, indicating the end of the
waiting period that is required before electing a (Backup) Designated Router across all
OSPF areas and interfaces.
backup
The sum total number of Backup Designated Routers on the attached network for all
OSPF areas and interfaces.
nbr change
The sum total number of changes in the set of bidirectional neighbors associated with
any interface across all OSPF areas.
