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 [summa
ry]
Syntax Description
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.
• Return code distribution among the received MPLS echo reply packets.
• Statistics of sent and received MPLS echo packets, and counts of incomplete packet dispatches and
timed out MPLS echo requests.
If you enter the summa
ry 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 summa
ry keyword is not specified:
Router# show mpls oam echo statistics
Cisco TLV version: RFC 4379 Compliant
Return 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
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).
