fpc (MX Series 5G Universal Routing Platforms)


Hierarchy Level


Configure properties for the DPC or MPC and corresponding Packet Forwarding Engines to create tunnel interfaces.

(MX Series Virtual Chassis only) When you configure chassis properties for MPCs installed in a Virtual Chassis member router, statements included at the [edit chassis member member-id fpc slot slot-number] hierarchy level apply to the MPC in the specified slot number only on the specified member router in the Virtual Chassis. Statements included at the [edit chassis fpc slot slot-number] hierarchy level apply to the MPCs in the specified slot number on each member router in the Virtual Chassis.

Best Practice:

To ensure that the statement you use to configure MPC chassis properties in an MX Series Virtual Chassis applies to the intended member router and MPC, we recommend that you always include the member member-ID option before the fpc statement, where member-id is 0 or 1 for a two-member MX Series Virtual Chassis.


fpc slot-number—Specify the slot number of the DPC.

  • Range: 0 through 11
