trace mpls pseudowire destination-address vc-id segment segment-number segment-number Where:
-
destination-address is the address of the next S-PE router from the original of the trace.
-
vc-id is the VC ID of the segment from which the trace command is issued.
-
segment-number indicates the segment upon which the trace operation will act. If you enter two segment numbers, the traceroute operation will perform a trace on that range of routers.
The following examples use the topology shown in the second figure above :
-
To perform a trace operation from T-PE1 to segment 2 of the multisegment pseudowire, enter the following command:
trace mpls pseudowire <addr-of-S-PE1> <vc-id between T-PE1 and S-PE1> segment 2 This example performs a trace from T-PE1 to S-PE2.
-
To perform a trace operation on a range of segments, enter the following command. This example performs a trace from S-PE2 to T-PE2.
trace mpls pseudowire <addr-of-S-PE1> <vc-id between T-PE1 and S-PE1> segment 2 4 The following command performs a trace operation on S-PE router 10.10.10.9, on segment 1 and then on segment 2:
Example:
router# trace mpls pseudowire 10.10.10.9 220 segment 1
Tracing MS-PW segments within range [1-1] peer address 10.10.10.9 and timeout 2 seconds
Codes: '!' - success, 'Q' - request not sent, '.' - timeout,
'L' - labeled output interface, 'B' - unlabeled output interface,
'D' - DS Map mismatch, 'F' - no FEC mapping, 'f' - FEC mismatch,
'M' - malformed request, 'm' - unsupported tlvs, 'N' - no label entry,
'P' - no rx intf label prot, 'p' - premature termination of LSP,
'R' - transit router, 'I' - unknown upstream index,
'X' - unknown return code, 'x' - return code 0
Type escape sequence to abort.
