Interfaces

  • Permanent MAC address for aggregated Ethernet interface (MX240, MX480, MX960, MX2008, MX2010, MX2020, and VMX)—Starting in Junos OS Release 23.1R1, the number of static MAC addresses increases for:

    • VMX, MX240, MX480, and MX960 from 16 to 80.

    • MX2008, MX2010, and MX2020 from 0 to 80.

    The chassid process (chassisd) now allocates MAC addresses to aggregated Ethernet interfaces in this pattern:

    • First 16 interfaces receive addresses from a private MAC pool.

    • Next 64 ae interfaces receive addresses from a reserved public MAC pool.

    • Rest of the ae interfaces receive addresses from a public MAC pool.
