Enabling Unidirectional Traffic Flow on Physical Interfaces

By default, physical interfaces are bidirectional; that is, they both transmit and receive traffic. You can configure unidirectional link mode on a 10-Gigabit Ethernet interface that creates two new physical interfaces that are unidirectional. The new transmit-only and receive-only interfaces operate independently, but both are subordinate to the original parent interface.

To enable unidirectional link mode on a physical interface, perform the following steps:

  1. In configuration mode, go to the [edit interfaces interface-name] hierarchy level:
    [edit]user@host# edit interfaces interface-name
  2. Configure the unidirectional option to create two new, unidirectional (transmit-only and receive-only) physical interfaces subordinate to the original parent interface.
    [edit interfaces interface-name]user@host# set unidirectional

Note: Unidirectional link mode is currently supported on only the following hardware:

  • 4–port 10–Gigabit Ethernet DPC on the MX960 router
  • 10–Gigabit Ethernet IQ2 PIC and 10–Gigabit Ethernet IQ2E PIC on the T Series router
