Field Descri
p
tion
MPLS trace route FEC Trace the LSPs for the specified FEC.
Destination address Destination IP address in the IP header.
TTL Number of hops.
Replier Address of the LSR that replied the request.
Time Time used to receive the reply, in milliseconds.
Type LSR type: Ingress, Transit, or Egress.
Downstream
Address of the downstream LSR and the label assigned by
the downstream LSR.
ReturnCode
Return code. The number in parentheses represents a return
subcode.
tracert mpls te
Use tracert mpls te to trace an MPLS TE tunnel from the ingress node to the egress node. You can locate
the error node according to the reply information.

Parameters
-a source-ip: Specifies the source address for MPLS echo request packets. If you do not specify this option,
the command uses the primary IP address of the outgoing interface as the source address for MPLS echo
requests.
-exp exp-value: Specifies the EXP value for MPLS echo request packets, in the range of 0 to 7. The default
is 0.
-h ttl-value: Specifies the maximum TTL value for MPLS echo request packets (the maximum number of
hops to be inspected). The value range for the ttl-value argument is 1 to 255, and the default is 30.
-r reply-mode: Specifies the reply mode of the receiver in response to MPLS echo request packets. The
reply-mode argument can be 1, 2, or 3. 1 means "Do not reply," 2 means "Reply by using a UDP
packet," and 3 means "reply by using a UDP packet that carries the Router Alert option." The default is
2.
-rtos tos-value: Specifies the ToS value in the IP header of an MPLS echo reply packet. The value range
is 0 to 7, and the default value is 6.
-t time-out: Specifies the timeout interval for the reply to an MPLS echo request. The value range is 0 to
65535 milliseconds, and the default is 2000 milliseconds.
