Example: Configuring Chassis Cluster Interface Monitoring

This example shows how to specify that an interface be monitored by a specific redundancy group for automatic failover to another node. You assign a weight to the interface to be monitored.

Requirements

Before you begin, create a redundancy group. See Example: Configuring Chassis Cluster Redundancy Groups.

Overview

You can configure your system to monitor the health of the interfaces belonging to a redundancy group. When you assign a weight to an interface to be monitored, the system monitors the interface for availability. If a physical interface fails, the weight is deducted from the corresponding redundancy group's threshold. Every redundancy group has a threshold of 255. If the threshold hits 0, a failover is triggered, even if the redundancy group is in manual failover mode and the preempt option is not enabled.

In this example, you configure a weight of 255 to the ge-7/0/3 interface in the redundancy group named 1.

Configuration

Step-by-Step Procedure

To configure chassis cluster interface monitoring:

Specify the interface to be monitored by a redundancy group.
{primary:node0}[edit]user@host# set chassis cluster redundancy-group 1 interface-monitor ge-7/0/3 weight 255
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 chassis cluster interfaces command.
