Example: Configuring Chassis Cluster Redundant Ethernet Interface Link Aggregation Groups (CLI)

Chassis cluster configuration supports including more than one child interface per node in a redundant Ethernet interface. When at least two physical child interface links from each node are included in a redundant Ethernet interface configuration, the interfaces are combined within the redundant Ethernet interface to form a redundant Ethernet interface link aggregation group.

Note: For the aggregation to take place, the switch used to connect the nodes in the cluster must enable IEEE 802.3ad link aggregation for the redundant Ethernet interface physical child links on each node. Because most switches support IEEE 802.3ad and are also Link Aggregation Control Protocol (LACP) capable, it is recommended that you enable LACP on the SRX Series devices. In cases where LACP is not available on the switch, you should not enable LACP on the SRX Series devices.

All six of these Gigabit Ethernet interfaces, three from each node, have now been assigned to reth1. All other steps related to redundant Ethernet interface configuration are the same as those for a redundant Ethernet interface with only two child interfaces.

Note: A maximum of 8 physical interfaces per node in a cluster, for a total of 16 child interfaces, can be assigned to a single redundant Ethernet interface when a redundant Ethernet interface LAG is being configured.
