Example: Configuring Link Aggregation Groups Using Uplink Virtual Chassis Ports
Requirements
You can form link aggregation groups (LAGs) between Virtual Chassis member switches
in different wiring closets using uplink Virtual Chassis ports (VCPs) and, on J-EX4200-24F
switches, network VCPs. LAGs balance traffic across the member links, increase the
uplink bandwidth, and provide increased availability. To form LAGs using uplink or network
VCPs, you configure the uplink module interfaces or network interfaces on the member
switches as VCPs and connect the VCPs using fiber-optic cables. For the LAGs to form,
the uplink or network VCPs on each member switch that will form a LAG must operate
at the same link speed and you must interconnect at least two uplink or network VCPs
on each of those members. You can connect uplink or network VCPs operating at different
link speeds, but they will not form a LAG.
NOTE: The LAGs formed by VCPs are different from LAGs formed by Virtual
Chassis network interfaces. For more information on LAGs formed by network
interfaces, see "Understanding Virtual Chassis Configurations and Link
Aggregation" on page 702.
This example shows how to configure uplink module interfaces and network interfaces
as VCPs on multiple member switches of a Virtual Chassis configuration and then connect
them to form LAGs:

This example uses the following hardware and software components:
Five J-EX4200 switches, one of which is a J-EX4200-24F model
Four uplink modules
