    Monitoring RSVP Path State Control Blocks, Reservation State Control Blocks, or Sessions

    Purpose

    Display RSVP path state control blocks, reservation state control blocks, or session information about the virtual router to assist in debugging. A session can be any of the following:

    • ingress session—Originating on the router
    • egress session—Terminating on the router
    • transit session—Travelling through the router

    Action

    To display path state control blocks for an ingress session:
