Setting an Uplink Port as a Virtual Chassis Port on an EX4500 or EX4550 Switch (CLI Procedure)
You can set any optical port on an EX4500 switch as a Virtual Chassis port (VCP). Setting an optical port as a VCP is especially useful in cases in which you have to connect Virtual Chassis members together across a distance that is greater than the longest VCP cable can breach.
You can use the optical ports to connect EX4200 switches, EX4500 switches, and EX4550 switches together into a Virtual Chassis. All supported optical connections between EX4200, EX4500, and EX4550 switches can be configured as VCPs.
 | Note: The Virtual Chassis module for EX4500 switches is a field-replacable unit (FRU) that is not shipped with all EX4500 switch models but can be purchased separately. See Virtual Chassis Module in EX4500 Switches and EX4500 Switch Models. |
Before you set an uplink port as a VCP on an EX4500 or EX4550 switch:
- Cable the uplink port connections.
To set the optical onnection as a VCP:
- Set the 10-Gigabit Ethernet SFP+ port as a VCP interface:
user@switch> request virtual-chassis vc-port set pic-slot pic-slot-number port port-numberwhere:
- pic-slot-number—The PIC slot number, which is 0 when specifying a native port, 1 when specifying a port on the uplink module in PIC slot number 1, and 2 when specifying a port on an uplink module in PIC slot number 2.
- port-number—The port number on the switch or uplink module.
- Log onto the other EX4500 switch, and set the other end
of the connection as a VCP interface:
user@switch> request virtual-chassis vc-port set pic-slot pic-slot-number port port-number
