Select Device > Monitor > ISIS > Circuit Table.
With a circuit selected, click Circuit Errors.
Depending on how the selected circuit is configured, you will see at least one of the following categories:
lanlevel1(1)—LAN Level 1
lanlevel1(2)—LAN Level 2
p2pcircuit(3)—point-to-point circuit
The following information appears:
Adjacency Changes (ciiCircAdjChanges)
Adjacency Numbers (ciiCircNumAdj)
Initialization Fails (ciiCircInitFails)
Rejected Adjacencies (ciiCircRejAdjs)
ID Field Len Mismatches (ciiCircIDFieldLenMismatches)
Max Area Addr Mismatches (ciiCircMaxAreaAddrMismatches)
Authentication Type Fails (ciiCircAuthTypeFails)
Number of times an adjacency state change has occurred on this circuit.
Number of adjacencies on this circuit.
Number of times the initialization of this circuit has failed. This includes events such as PPP NCP failures.
Note: Failures to form an adjacency are indicated by ciiCircRejAdjs.
Number of times an adjacency has been rejected on this circuit.
Number of times an IS-IS control PDU with an ID field length that is different than the one configured for this system has been received.
Number of times an IS-IS control PDU with a max area address value that is different than the one configured for this system has been received.
Number of times an IS-IS control PDU with an authentication type that is different than the one configured for this system has been received.
Number of times an IS-IS control PDU with the correct authentication type has failed to be authenticated.
Number of times the designated IS has changed at this level on this circuit.
Note: If the circuit is a point-to-point circuit, then the value of this object is zero.
