User manual

- 801 -
AS Border Router Count - The total number of Autonomous System border routers reachable within
this area. This is initially zero, and is calculated in each SPF Pass.
Area LSA Count - The total number of link-state advertisements in this area's link-state database,
excluding AS External LSAs.
IP Address - The IP address of the interface.
Interface Events - The number of times the specified OSPF interface has changed its state, or an
error has occurred.
Virtual Events - The number of state changes or errors that have occurred on this virtual link.
Neighbor Events - The number of times this neighbor relationship has changed state, or an error has
occurred.
External LSA Count - The number of external (LS type 5) link-state advertisements in the link-state
database.
Sent packets - The number of OSPF packets transmitted on the interface.
Received packets - The number of valid OSPF packets received on the interface.
Discards - The number of received OSPF packets discarded because of an error in the packet or an
error in processing the packet.
Bad Version - The number of received OSPF packets whose version field in the OSPF header does
not match the version of the OSPF process handling the packet.
Source Not On Local Subnet - The number of received packets discarded because the source IP
address is not within a subnet configured on a local interface.
Virtual Link Not Found - The number of received OSPF packets discarded where the ingress
interface is in a non-backbone area and the OSPF header identifies the packet as belonging to the
backbone, but OSPF does not have a virtual link to the packet's sender.
Area Mismatch - The number of OSPF packets discarded because the area ID in the OSPF header
is not the area ID configured on the ingress interface.
Invalid Destination Address - The number of OSPF packets discarded because the packet's
destination IP address is not the address of the ingress interface and is not the AllDrRouters or
AllSpfRouters multicast addresses.
Wrong Authentication Type - The number of packets discarded because the authentication type
specified in the OSPF header does not match the authentication type configured on the ingress
interface.
Authentication Failure - The number of OSPF packets dropped because the sender is not an
existing neighbor or the sender's IP address does not match the previously recorded IP address for
that neighbor.
No Neighbor at Source Address - The number of OSPF packets dropped because the sender is not
an existing neighbor or the sender's IP address does not match the previously recorded IP address
for that neighbor.
Invalid OSPF Packet Type - The number of OSPF packets discarded because the packet type field
in the OSPF header is not a known type.
Hellos Ignored - The number of received Hello packets that were ignored by this router from the new
neighbors after the limit has been reached for the number of neighbors on an interface or on the
system as a whole.
Hellos Sent - The number of Hello packets sent on this interface by this router.
Hellos Received - The number of Hello packets received on this interface by this router.
DD Packets Sent - The number of Database Description packets sent on this interface by this router.
