HP 6125G Command Reference Manual page 14

-vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the destination belongs, where
vpn-instance-name is a case-sensitive string of 1 to 31 characters. If the destination is on the public
network, do not specify this option.
-w timeout: Specifies the timeout time of the reply packet of a probe packet, which is in the range of 1
to 65535 milliseconds and defaults to 5000 milliseconds.
host: Specifies the IP address or host name (a string of 1 to 255 characters) for the destination.
Description
Use tracert to trace the path that the packets traverse from source to destination.
In the event of network failure, you can use the tracert command to determine the failed nodes.
The output from the tracert command includes IP addresses of all the Layer 3 devices that the packets
traverse from source to destination. Asterisks (* * *) are displayed if the device cannot reply with an
ICMP error message (probably because the destination is unreachable or sending ICMP
timeout/destination unreachable packets is disabled).
To abort the tracert operation during the execution of the command, press Ctrl+C.

Description
Display the route that the IP packets traverse from the current device to
the device whose IP address is 1.1.2.2.
Maximum number of hops of the probe packets, which can be set
through the -m keyword.
Number of bytes of a probe packet.
During the execution of the command, you can press Ctrl+C to abort
the tracert operation.
