System Management

  • Support for PTP over Ethernet and hybrid mode over LAG interfaces (MX240, MX480, and MX960)—The MPC2E NG and MPC3E NG line cards support Precision Time Protocol (PTP) over Ethernet and hybrid mode over a link aggregation group (LAG).


    There could be some performance limitations during a switchover from the active line card to the secondary line card and vice versa in a multi-line card scenario because of hardware limitations.

    If an unsupported line card is configured as the primary or secondary interface, the configuration goes through, but an error message is displayed in the output of the show ptp slave/primary CLI command. You must configure only supported line cards (MPC5E and MPC6E) to avoid this issue.
