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 connectan 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 master 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 master 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.
