Cisco IOS Multiprotocol Label Switching Command Reference
January 2010
Pseudowire Usage
The following keywords are not available with the trace mpls pseudowire command:
• flags
• force-explicit-null
• output
• revision
• ttl
Revision Keyword Usage
The revision keyword allows you to issue a trace mpls ipv4 or trace mpls traffic-eng command based
on the format of the TLV. Table 164 lists the revision option and usage guidelines for each option.
Examples The following example shows how to trace packets through an MPLS LDP LSP:
Router# trace mpls ipv4 10.131.191.252/32
Alternatively, you can use the interactive mode:
Protocol [ip]: mpls
Target IPv4, pseudowire or traffic-eng [ipv4]: <ipv4 |pseudowire |tunnel> ipv4
Target IPv4 address: 10.131.191.252
Target mask: /32

1. If you do not specify the revision keyword, the software uses the latest version.
Not supported in Cisco IOS Release 12.4(11)T or later releases.
Version 1 (draft-ietf-mpls-ping-03)
For a device running Cisco IOS Release 12.0(27)S3 or a later release, you must use
th
e revision 1 k
eyword when you send LSP ping or LSP traceroute commands to
devices running Cisco IOS Release 12.0(27)S1 or 12.0(27)S2.
2 Version 2 functionality was replaced by Version 3 functionality before any images
w
ere shipped.
3 Version 3 (draft-ietf-mpls-ping-03).
• For a device implementing Version 3 (Cisco IOS Release 12.0(27)S3 or a later
release), you must use the revision 1 ke
yword when you send the LSP ping or
LSP traceroute command to a device implementing Version 1 (that is, either
Cisc
o IOS Release 12.0(27)S1 or Release 12.0(27)S2).
• A ping mpls pseudowire command does not work with devices running
Cisco IOS Release 12.0(27)S1 or Release 12.0(27)S2.
4
• Version 8 (draft-ietf-mpls-ping-08)—Applicable before Cisco IOS
Release 12.4(11)T. All echo packet’s TLVs are formatted as specified in
Ve
rs ion 8.
• RFC 4379 compliant—Applicable after Cisco IOS Release 12.4(11)T. All echo
packet’s TLVs are formatted as specified in RFC 4379.
This is the recommended version.
