The "hop limit" field in this prompt information has the same meaning as the "ttl" field in the prompt
information displayed by the IPv4 ping command, indicating the TTL value in the ICMPv6 echo request.

Parameters
-a source-ip: Specifies the source IP address of a tracert packet. It must be a legal IP address
configured on the device.
-f first-ttl: Specifies the first TTL, that is, the allowed number of hops for the first packet, in the range 1 to
255. It defaults to 1 and must be less than the maximum TTL.
-m max-ttl: Specifies the maximum TTL, that is, the maximum allowed number of hops for a packet, in
the range 1 to 255. It defaults to 30, and must be greater than the first TTL.
-p port: Specifies the UDP port number of the destination device, in the range 1 to 65535. The default
value is 33434. You do not need to modify this parameter.
-q packet-number: Specifies the number of probe packets sent each time, in the range 1 to 65535. The
default value is 3.
-vpn-instance vpn-instance-name: Specifies the name of an MPLS VPN instance, which is a string of 1
to 31 characters.
-w timeout: Specifies the timeout time of the reply packet of a probe packet, in the range 1 to 65535, in
milliseconds. The default value is 5000 ms.
remote-system: IP address or host name (a string of 1 to 20 characters) of the destination device.
Description
Use the tracert command to trace the routers the packets traverse from the source to the destination
device.
After having identified network failure with the ping command, you can use the tracert command to
determine the failed node(s).
