Example: Configuring Chassis Cluster Redundancy Groups (CLI)

A redundancy group is an abstract entity that includes and manages a collection of objects. A redundancy group can be primary on only one node at a time.

Before you begin, complete the following tasks:

Before you can create redundant Ethernet interfaces, you must first create their redundancy groups.

Use the following command in configuration mode to specify the number of gratuitous ARP requests that an interface can send to notify other network devices of its presence after the redundancy group it belongs to has failed over:

{primary:node1}user@host# set chassis cluster redundancy-group 1 gratuitous-arp-count 4

Use the following command in configuration mode to identify an interface to be monitored by a specific redundancy group and give it a weight. You can configure a redundancy group to monitor any interfaces, not only those belonging to its redundant Ethernet interfaces.

{primary:node1}user@host# set chassis cluster redundancy-group 1 interface-monitor fe-3/1/1/1 weight 100

Use the following commands in configuration mode to specify a redundancy group's priority for primacy on each node of the cluster. The higher number takes precedence.

{primary:node1}user@host# set chassis cluster redundancy-group 1 node 1 priority 100{secondary:node0}user@host# set chassis cluster redundancy-group 1 node 0 priority 200

Use the following command in configuration mode to specify if a node with a higher priority can initiate a failover to become primary for the redundancy group:

{primary:node1}user@host# set chassis cluster redundancy-group 1 preempt

Use the following command in configuration mode to specify the minimum interval to be allowed between back-to-back failovers for the redundancy group:

{primary:node1}user@host# set chassis cluster redundancy-group 1 hold-down-interval 6
