Release Information

Statement introduced in Junos OS Release 9.4 for EX Series switches.

Statement introduced in Junos OS Release 13.2 for the QFX Series.


Specify the port of the SFP+ uplink module for which you want to configure the operating mode, or specify the line card slot for which you want to assign a power priority.


On an EX6200 switch, you cannot change the power priority of a slot containing a Switch Fabric and Routing Engine (SRE) module. Although the CLI allows you to set a power priority for the slot, your change does not take effect, and the power priority remains 0. A message is sent to the system log to inform you that changing the power priority of the slot is unsupported.

For generic routing encapsulation (GRE) tunneling, use the fpc statement along with the tunnel-port statement to specify the port on the switch that you want to convert to a GRE tunnel port.


slot—Number of the slot:

  • 0—EX3200 and standalone EX4200, EX4500, and EX4550 switches. The FPC value refers to the switch itself.

  • 0–9—EX4200, EX4500, or EX4550 switch in a Virtual Chassis configuration. The value corresponds to the switch’s member ID.

  • 0–3 and 6–9—EX6210 switch. The slot is a line card slot.

    4–5—The slot is a line card slot or an SRE module slot.

  • 0–7—EX8208 switch. The slot is a line card slot.

  • 0–15—EX8216 switch. The slot is a line card slot.
