    Solution

    How to Enable?

    PMI

    Include the power-mode-ipsec and gre-performance-acceleration statements at the [edit security flow] hierarchy level.

    Note:

    PMI supports both IPsec and GRE. In this case, traffic flows through the PMI data path.

    GRE acceleration

    Include the gre-performance-acceleration statement at the [edit security flow] hierarchy level.  

    Note:

    By default, gre-performance-acceleration is turned off. In this case, traffic flows through the GRE acceleration data path.

    [See gre-performance-acceleration (Security Flow), flow (Security Flow), and show security flow status.]
