    Connecting J Series Devices to Create a Chassis Cluster Overview

    To create a J Series chassis cluster, you must physically connect a pair of the same kind of supported J Series devices back-to-back over a pair of Gigabit Ethernet connections. The connection that serves as the control link must be the built-in interface ge-0/0/3. The fabric link connection can be a combination of any pair of Gigabit Ethernet interfaces on the devices.

    Note: You can connect two fabric links between the two devices in the cluster to reduce the chance of fabric link failure. See Understanding Chassis Cluster Dual Fabric Links.

    Figure 1 shows two J Series devices connected using the built-in interfaces for both the fabric and control links.

    Note: When chassis clustering is enabled on a J Series router, two interface ports are used to link the two devices: the ge-0/0/3 interface (fxp1 port) is used for the control interface and one port is used for the fabric link (using either one of the built-in interfaces (ge-0/0/0 or ge-0/0/1) or one of the ports of a uPIM). Also, the ge-0/0/2 interface (fxp0 port) is used for the management link. This means that three of the four onboard Gigabit Ethernet ports are in use; if additional ports are required for transit traffic, then a PIM or uPIM is required.
