o adjacency state change
Support: All
Generated when the status attribute state of a routing circuit
adjacency entity belonging to the circuit changes from up to

this event is generated for point-to-point links only.

o circuit change
Support: All
Generated when the status attribute state of the circuit changes
from off to on, or vice versa.
Argument:
disable The reason that the circuit status changed from on to
reason off. If the disable occurred because of a management
circuit disable action, the reason is a Management
Action (1). If the disable occurs for any other
reason, it is a Protocol Action (0).

received that either cannot be parsed or contains an incorrect
checksum.

Generated when a corrupted link-state packet is received.
Argument:

o corrupted phaseiv routing packet received
Support: L1,L2
Generated when a corrupted Phase IV routing packet is received.
Argument:
phase iv Phase IV ID of the Phase IV routing message that
id caused the event to be generated.
o da adjacency change
Support: All
Generated when the state of a DA adjacency on the circuit changes
from up to down or from down to up. For these purposes, the
states up and up/dormant are considered up and any other state is
considered down. This attribute is supported only if the circuit
type is x25 da.
Arguments:
adjacency Name of the adjacency to which the event refers.
name
new Current state of the adjacency.
adjacency
state down Adjacency state is now down.

reason Reason why the adjacency state changed to down.
o exceeded maximum svc adjacencies
Support: End,L2 (DA
circuits only)
Generated when there is no free adjacency on which to establish
an SVC for a new destination.
o id reachability change
Support: All
Generated when an ID is added to or removed from the endnodeID
status of an adjacency on this circuit. For end nodes this event
is generated for point-to-point links only.
Arguments:
adjacency Name of the adjacency to which the event refers.
name
adjacent Node IDs of the adjacent node.
node
reason Reason why the adjacency state changed to down.
o initialization failure
Support: All
Generated when an attempt to initialize with an adjacent node
fails, either because of version skew or area mismatch.
Arguments:
adjacent Node IDs of adjacent nodes.
node
reason Reason why the event was generated. See possible
reasons described under the adjacency state change
event.
o ip adjacency state change

Generated when the status attribute state of a routing circuit
ip adjacency entity belonging to this circuit changes from up (or
up/dormant) to some other value, or the reverse.

IP address
new IP New state of the IP adjacency.
adjacency
state up Either up or up/dormant
down Any other state
reason Reason for the state change.
o ip fragmentation failure

Generated when an IP packet that requires fragmentation in
order to be transmitted has an IP header that requests "do not
fragment."
Arguments:
destination Destination IP address of the IP packet.

is x25 static outgoing.
