Example: Configuring Chassis Cluster Control Link Recovery

This example shows how to enable control link recovery, which allows the system to automatically take over after the control link recovers from a failure.

Requirements

Before you begin:

Overview

You can enable the system to perform control link recovery automatically. After the control link recovers, the system takes the following actions:

  • It checks whether it receives at least 30 consecutive heartbeats on the control link or, in the case of dual control links (SRX1400, SRX5600, SRX5800, and SRX3000 lines only), on either control link. This is to ensure that the control link is not flapping and is healthy.
  • After it determines that the control link is healthy, the system issues an automatic reboot on the node that was disabled when the control link failed. When the disabled node reboots, it can rejoin the cluster. There is no need for any manual intervention.

In this example, you enable chassis cluster control link recovery.

Configuration

Step-by-Step Procedure

To enable chassis cluster control-link-recovery:

  1. Enable control link recovery.
    {primary:node0}[edit] user@host# set chassis cluster control-link-recovery
  2. If you are done configuring the device, commit the configuration.
    {primary:node0}[edit] user@host# commit

Verification

To verify the configuration is working properly, enter the show configuration chassis cluster command.
