Usage Guidelines

Usage Scenario

On an IS-IS network, IS-IS adjacency changes pose a threat to network stability, causing frequent route convergence which consumes a lot of memory resources and possible traffic loss. Therefore, diagnose the fault immediately when the IS-IS adjacency changes.

To locate the fault, run the log-peer-change command to enable the output of IS-IS adjacency changes and record the changes in the log.

Precautions

IS-IS adjacency changes are recorded only when the terminal monitor and log-peer-change commands are run.

Example

# Enable the output of IS-IS adjacency changes on the current switch.
