Chapter 44: Virtual Chassis—Configuration Examples
We will configure the uplink module interfaces on three of the switches as uplink VCPs.
On the J-EX4200-24F switch we will configure two of the network interfaces as VCPs.
We will interconnect two of the uplink VCPs on SWA-0 with two of the uplink VCPs on
SWA-2. Similarly, we will interconnect the two uplink VCPs on SWA-1 with the two uplink
VCPs on SWA-3. Finally, we will connect the two remaining uplink VCPs on SWA-0 with
two network VCPs on SWA-4. As a result, three LAGs will be automatically formed.
Figure 21 on page 771 shows the interconnections used to form LAGs using uplink VCPs
and the network VCPs after the procedure below has been completed.

Configuration
To configure the Virtual Chassis uplink module interfaces and network interfaces as
uplink VCPs and interconnect them between two wiring closets to form LAGs, perform
these tasks:
