# 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:

    host1#show mpls rsvp psb
      PSB: Sender 223.10.1.1 LSPId 1 timeout -- InLabel --
           PHopIntf

           Flags : InUse
                   RroRequired
                   PathRefreshSent

To display reservation state control blocks for an ingress session:

    host1#show mpls rsvp rsb
