show mpls oam echo statistics
To display statistics about Multiprotocol Label Switching (MPLS) Operation, Administration, and Maintenance (OAM) echo request packets, use the show mpls oam echo statistics command in privileged EXEC mode.
show mpls oam echo statistics [summary]
Syntax Description
summary
(Optional) Displays summary information about the echo request packets (that is, the type, length, values (TLVs) version and the return codes of echo packets are not displayed).
Command Modes
Privileged EXEC
Command History
Usage Guidelines
You can use the show mpls oam echo statistics command to display the following:
•
Currently configured TLV version for MPLS OAM operations.
•
•
If you enter the summary keyword, the Echo Reply count shows all the echo reply packets, regardless of whether they are valid responses to a sent request packet. Therefore, the number of return codes will not match the number of echo reply packets received.
Examples
The following example displays sample detailed output when the summary keyword is not specified:
Router# show mpls oam echo statisticsCisco TLV version: RFC 4379 CompliantReturn code distribution:!—Success (3) - 5 B—Unlabeled output interface (9) - 0 D—DS map mismatch (5) - 0 f—Forward Error Correction (FEC) mismatch (10) - 0 F—No FEC mapping (4) - 0 I—Unknown upstream interface index (6) - 0 L—Labeled output interface (8) - 0 m—Unsupported TLVs (2) - 0 M—Malformed echo request (1) - 0 N—No label entry (11) - 0 p—Premature termination of link-state packet (LSP) (13) - 0 P—No receive interface label protocol (12) - 0 U—Reserved (7) - 0 x—No return code (0) - 0 X—Undefined return code - 0Echo Requests: sent (5)/received (0)/timedout (0)/unsent (0) Echo Replies: sent (0)/received (5)/unsent (0)The following example displays sample output when the summary keyword is specified:

Syntax Description
Command Default
General information about each MPLS TE tunnel known to the router is displayed.
Command Modes
User EXEC (>)
Privileged EXEC (#)Command History
Usage Guidelines
To select the tunnels for which information is displayed, use the auto-tunnel, backup-tunnel, attributes, destination, interface, name, name-regexp, property, role, source-id, suboptimal constraints, up, and down keywords singly or combined.
To select the type of information displayed about the selected tunnels, use the accounting, backup, protection, statistics, and summary keywords.
The auto-tunnel, backup-tunnel, and property keywords display the same information, except that the property keyword restricts the display to autotunnels, backup tunnels, or tunnels that are Fast Reroute-protected.
The name-regexp keyword displays output for each tunnel whose name contains a specified string. For example, if there are tunnels named iou-100-t1, iou-100-t2, and iou-100-t100, the show mpls traffic-eng tunnels name-regexp iou-100 command displays output for the three tunnels whose name contains the string iou-100.
If you specify the name keyword, there is command output only if the command name is an exact match; for example, iou-100-t1.
The nonbrief and nonsummary formats of the output contain the history of the LSP selection.

The "reroute pending" status is not displayed during the delayed clean operation. There is no change to data forwarding or tunnel creation. You might see the "reroute pending" status for a shorter time. In the following example, the "reroute pending" message appears, but the "delayed clean" message does not.

sshow mpls traffic-eng tunnels statistics
To display event counters for one or more Multiprotocol Label Switching (MPLS) traffic engineering tunnels, use the show mpls traffic-eng tunnels statistics command in user EXEC and privileged EXEC mode.
show mpls traffic-eng tunnels [tunnel tunnel-name] statistics [summary]
Syntax Description
tunnel tunnel-name
(Optional) Displays event counters accumulated for the specified tunnel.
summary
(Optional) Displays event counters accumulated for all tunnels.
Defaults
If you enter the command without any keywords, the command displays the event counters for every MPLS traffic engineering tunnel interface configured on the router.
Command Modes
User EXEC (>)
Privileged EXEC mode (#)Command History
Usage Guidelines
A label switching router (LSR) maintains counters for each MPLS traffic engineering tunnel headend that counts significant events for the tunnel, such as state transitions for the tunnel, changes to the tunnel path, and various signaling failures. You can use the show mpls traffic-eng tunnels statistics command to display these counters for a single tunnel, for every tunnel, or for all tunnels (accumulated values). Displaying the counters is often useful for troubleshooting tunnel problems.
Examples
The following are examples of output from the show mpls traffic-eng tunnels statistics command:
