R3721-F3210-F3171-HP High-End Firewalls System Management and Maintenance Command Reference-6PW101

8
host: IP address or host name (a string of 1 to 255 characters) of the destination.
Description
Use tracert to trace the path the packets traverse from source to destination.
After having identified network failure with the ping command, use the tracert command to determine the
failed node(s).
Output from the tracert command includes IP addresses of all the Layer 3 devices the packets traverse
from source to destination. If a device times out, asterisks (* * *) are displayed.
To abort the tracert operation during the execution of the command, press Ctrl+C.

tion
traceroute to 1.1.2.2(1.1.2.2)
Display the route the IP packets traverse from the current device to the
device whose IP address is 1.1.2.2.
hops max
Maximum number of hops of the probe packets, which can be set
through the -m keyword.
bytes packet Number of bytes of a probe packet.
press CTRL_C to break
During the execution of the command, you can press Ctrl+C to abort
the tracert operation.
1 1.1.1.2 673 ms 425 ms 30 ms
Probe result of the probe packets whose TTL is 1, including the IP
address of the first hop and the roundtrip time of three probe packets.
Number of packets that can be sent in each probe can be set through
the -q keyword.
