Displaying RSVP information

You can display global RSVP information, including the version information, the status of RSVP interfaces, RSVP session information, and RSVP statistics.

To display global RSVP information, including the RSVP version number, as well as the refresh interval and refresh multiple, use the show mpls rsvp command.

vyatta@vyatta:~$ show mpls rsvp

Total 1 displayed, Up 1, Down 0.

To display a count of the total number of configured, ingress, egress and transit RSVP sessions, use the show mpls rsvp session count command.

vyatta@vyatta:~$ show mpls rsvp session count 
Total configured: 3, Up 3, Down 0

Total transit sessions: 0, Up 0, Down 0
Total egress sessions: 1, Up 1, Down 0

To display detailed session information, use the show mpls rsvp session [ egress | ingress | transit ] [ down | up ] detail command. The default is to show all sessions. You can limit the output to just egress, ingress or transit sessions and/or sessions that are up or down.

vyatta@vyatta:~$ show mpls rsvp session egress detail

To display detailed session information for a specific tunnel, use the show mpls rsvp session name <name> [ primary | secondary ] command. The default is to show all sessions. You can limit the output to just the primary or secondary configured session.

vyatta@vyatta:~$ show mpls rsvp session name t8 primary

Displaying RSVP statistics

The device constantly gathers RSVP statistics. RSVP statistics are collected from the time RSVP is enabled, as well as from the last time the RSVP statistics counters were cleared.

To display the RSVP statistics, use the following command:

vyatta@vyatta:~$ show mpls rsvp statistics
  PacketType              Total
                   Sent      Received
  Path                9            2
  PathErr             0            0
  PathTear            2            0
  Resv FF             0            0
  Resv WF             0            0
  Resv SE             2           10
  Resv Err            0            0
  ResvTear            0            0
  ResvConf            0            0
  Hello               0            0
  Bundle              0            0
  Ack                 0            0
  SRefresh          129          131
  Notify              0            0

To clear the packet statistics that are displayed by the show mpls rsvp statistics command, use the following command:

vyatta@vyatta:~$ clear mpls rsvp statistics

This command resets the counters listed under "since last clear" for the show mpls rsvp interface detail and show mpls rsvp statistics commands.

Displaying sessions using summary-refresh

To display sessions using summary-refresh, use the show mpls rsvp summary-refresh command.

vyatta@vyatta:~$ show mpls rsvp summary-refresh 
Neighbor Addr       Tunnel ID  LSP ID     Ingress             Egress

Displaying RSVP tunnels

To display a summary list of RSVP tunnels, use the show mpls rsvp tunnel command.

vyatta@vyatta:~$ show mpls rsvp tunnel
