trace
Perform a hop-by-hop fault localization check along an MPLS path.
Syntax: trace {ldp fec | rsvp tunnelName [lsp-id lsp-id]} [cisco-compat] [size] [timeout] [srcIPAddr] [destIPAddr] [expVal]
fec
Specifies the LDP FEC to be traced.
tunnelName
Specifies the RSVP tunnel to be traced.
lsp-id
Optionally specifies the LSP-ID.
cisco-
compatMust be specified if either the ingress or the egress of the path is a Cisco router.
size
Specifies the packet size of the trace. Valid Values: 100 - 10240. Default: 100.
srcIPAddr
Specifies the Source IP address of the trace.
destIPAddr
Specifies the Destination IP address of the trace.
expVal
Specifies the path EXP value for the trace. Valid Values: 0 - 7. Default: 0.
Description: MPLS Ping feature defines a trace route mechanism that is used for hop-by-hop fault localization as well as path tracing, including ECMP multi-path and members of a trunk interface
Use the trace command to perform a hop-by-hop fault localization check and path trace.
Use the mpls ping command to perform an MPLS connectivity check.
Factory Default: N/A
Command Mode: Privileged.
Example 1: In the following example, the mpls trace command traces the tunnel test:
router#trace mpls rsvp test
Tracing TE Tunnel test, timeout is 2 seconds:
1: 101.2.1.2 (101.2.1.2): 5.535 ms
Nexthop 102.3.1.2, label=30528, MTU=1500
2: 102.3.1.2 (102.3.1.2): 5.0 ms
