Ports Used to Interconnect Virtual Chassis Members
You can use the following ports to connect Virtual Chassis members:
•
On EX4200 switches:
•
The dedicated Virtual Chassis ports (VCPs) on each switch
•
SFP, SFP+, or XFP uplink module ports configured as VCPs
•
SFP network ports on EX4200-24F switches configured as VCPs
•
On EX4500 switches:
•
The dedicated VCPs on the Virtual Chassis module
•
SFP+ network ports configured as VCPs
•
SFP+ uplink module ports configured as VCPs
•
On EX4550 switches:
•
The dedicated VCPs on the Virtual Chassis module
•
SFP+ network ports configured as VCPs
•
SFP+ expansion module ports configured as VCPs
•
10GBASE-T network ports configured as VCPs
•
10GBASE-T expansion module ports configured as VCPs
•
40G QSFP+ expansion module ports configured as VCPs
NOTE: You can use the 10GBASE-T Ethernet network ports, 10GBASE-T expansion module
ports, and QSFP+ expansion module ports configured as VCPs to interconnect only EX4550
switches in a Virtual Chassis. These ports cannot be used to connect an EX4550 switch with
an EX4200 switch or an EX4500 switch in a Virtual Chassis.
Number of Switches, Required Software Releases, and Member Roles That You Configure in
the Virtual Chassis
A Virtual Chassis must have one member designated as the primary switch and one member designated
as the backup switch. All other switches in the configuration are designated as being in the linecard role.
You manage Virtual Chassis operation through the primary switch.
The number of switches that you can configure in a Virtual Chassis and the role that can be assigned to
each switch in a Virtual Chassis depend on the Juniper Networks Junos operating system (Junos OS) release
that is running on the switches.
