Explanation
 The specified event occurred on the specified
interface, causing its state to transition to the specified new state.
 state is
the Interface State Code. The Interface State Codes are described
in RFC 2328. See Related protocol specifications for directions
to get a copy of the RFC. The Interface State Codes can be one of
the following: 1
Down
1*
Suspend.  This state is not described in RFC2328. The interface
is suspended for one of the following reasons:  You issued a MODIFY command.
After the interface exceeded the futile neighbor state loop threshold
(DR_Max_adj_Attempt), the interface was unable to establish an adjacency
with a neighboring designated router.

in z/OS Communications Server: IP Configuration
Guide for more information about futile neighbor
state loops.

2
Backup. This state is not described in RFC 2328.  When more than
one OSPF interface is defined to the same subnet, only one of the
interfaces can be primary, meaning that it will be the interface to
carry the OSPF protocol traffic between OMPROUTE and the subnet. All
other interfaces to the same subnet will be in this state. Failure
of the primary interface will result in automatic switching of OSPF
traffic to one of the backup interfaces.

 event is the Interface Event
Code. The Interface Event Codes are described in RFC 2328. See Related protocol specifications for directions to get a copy of the RFC.
The Interface Event Codes can be one of the following:
 1
InterfaceUp
2
WaitTimer
3
BackupSeen
4
NeighborChange
5
LoopInd
6
UnloopInd
7
InterfaceDown
8
BackupUp. This state is not described in RFC 2328.  Lower-level
protocols have indicated that the network interface is operational.
This interface is one of multiple OSPF interfaces defined to the same
subnet and it is not the primary interface (the interface to carry
the OSPF protocol traffic between OMPROUTE and the subnet). The interface
will transition to Backup state.
9
InterfaceSuspend.  This event is not described in RFC2328. The
interface is suspended for one of the following reasons:  You issued a MODIFY command.
After the interface exceeded the futile neighbor state loop threshold
(DR_Max_adj_Attempt), the interface was unable to establish an adjacency
with a neighboring designated router.

in z/OS Communications Server: IP Configuration
Guide for more information about futile neighbor
state loops.

10
InterfaceActivate.  This event is not described in RFC2328. The
interface is activated for one of the following reasons:  You issued a MODIFY command.
The interface can now establish adjacency with a neighboring designated
router.

The interface will transition to one of the other states; however,
the interface will not transition to 1 (Down).   See the network design considerations with z/OS Communications Server information
in z/OS Communications Server: IP Configuration
Guide for more information about futile neighbor
state loops.
