View IS-IS Interface Counters
Use the following procedure to view the Intermediate-System-Intermediate-System (IS-IS) interface counters.
Procedure
- In the navigation pane, expand .
- Select Stats.
- Select the Interface Counters tab.
Interface Counters Field Descriptions
Use the data in the following table to use the Interface Counters tab.
| Name | Description | 
|---|---|
| Index | Shows a unique value identifying the IS-IS interface. | 
| Level | Shows the type of circuit that discovered the interface counters. The point to point Hello PDU includes both Layer 1 and Layer 2, and IS from a single adjacency on point to point links, therefore combining counts on point to point links into one group. | 
| AdjChanges | Shows the number of times an adjacency state change has occurred on this circuit. | 
| InitFails | Shows the number of times initialization of this circuit has failed. This counts events such as PPP NCP failures. Failures to form an adjacency are counted by isisCircRejAdjs. | 
| RejAdjs | Shows the number of times an adjacency has been rejected on this circuit. | 
| IDFieldLenMismatches | Shows the number of times an IS-IS control PDU with an ID field length different to that for this system has been received. | 
| MaxAreaAddrMismatches | Shows the number of times an IS-IS control PDU with a max area address field different to that for this system has been received. | 
| AuthFails | Shows the number of times an IS-IS control PDU with the correct auth type has failed to pass authentication validation. | 
| LANDesISChanges | Shows the number of times the Designated IS has changed on this circuit at this level. If the circuit is point to point, this count is zero. |
