Chassis VC0 and port 1 from CB0 and CB1 to Virtual Chassis VC1. Connect the port 0
cables to port 38 on Virtual Chassis VC0 (ge-0/0/38, ge-1/0/38, ge-2/0/38, and
ge-3/0/38), and connect the port 1 cables to port 38 on Virtual Chassis VC1 (ge-0/0/38,
ge-1/0/38, ge-2/0/38, and ge-3/0/38).
Table 81 on page 293 shows the port mappings
needed to extend the number of Interconnect devices in this example to four devices.

Figure 80 on page 293 shows the specific ports on the Node devices that you must connect
to the Virtual Chassis. In general, connect the first management port from a Node device
to the first Virtual Chassis, and the second management port to the second Virtual
Chassis.

In this specific example, for Node device Node0, connect port C0 (also known as me0)
to Virtual Chassis VC0 port ge-0/0/0, and connect port C1 (also known as me1) to Virtual
Chassis VC1 port ge-0/0/0.
For the remaining seven Node devices, connect port C0 to the ge-0/0/ X port on Virtual
Chassis VC0 that matches the Node device number. Similarly, connect port C1 to the
port on Virtual Chassis VC1 that matches the Node device number. For example, you
would connect Node device Node5 to port ge-0/0/5.
Table 82 on page 294 shows the full
set of port mappings for the Node devices in this example.
