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:

Action

To display path state control blocks for an ingress session:

To display reservation state control blocks for an ingress session:
