OS Release (continued)

EX9200 Virtual Chassis
You use Virtual Chassis ports (VCPs) to interconnect the member switches in a Virtual
Chassis.
Some switches have dedicated VCPs. Dedicated VCPs allow you to interconnect switches
without requiring any additional interface configuration.
These switches have dedicated VCPs:
EX4200 switches, on the rear panel
EX4500 switches, on the Virtual Chassis module
EX4550 switches, on the Virtual Chassis module
Some switches have ports that are configured as VCPs by default. You do not need to
explicitly configure those as VCPs to use them to interconnect those switches into a
Virtual Chassis.
To interconnect switches that do not have dedicated VCPs or to interconnect switches
across greater distances than allowed by a dedicated-VCP connection, you configure an
optical port as a VCP. You can configure those VCPs on these switches:
EX2200 switches, through an uplink port
NOTE: All RJ-45 interfaces, including built-in network ports with
10/100/1000BASE-T Gigabit Ethernet connectors and 1000BASE-T RJ-45
transceivers, on EX2200 and EX2200-C switches, can also be configured
into VCPs.
EX2300 switches, through uplink ports with SFP+ tranceivers and configured as VCPs
NOTE: You cannot use SFP tranceivers to form a Virtual Chassis on EX2300
switches.
