Understanding Active/Passive Chassis Cluster Deployment
In this case, a single device in the cluster is used to route all traffic while the other device is used only in the event of a failure (see Figure 102). When a failure occurs, the backup device becomes master and controls all forwarding.
Figure 102: Active/Passive Chassis Cluster Scenario (J Series Devices)
An active/passive chassis cluster can be achieved by using redundant Ethernet interfaces (reths) that are all assigned to the same redundancy group. If any of the interfaces in an active group in a node fails, the group is declared inactive and all the interfaces in the group will fail over to the other node.
This configuration minimizes the traffic over the fabric link because only one node in the cluster will forward traffic at any given time.
