
The path to the destination device is 1.1.1.2 to 1.1.2.2 to 1.1.3.2.
Prerequisites
Before you use a tracert command, perform the tasks in this section.
For an IPv4 network:
•
Enable sending of ICMP timeout packets on the intermediate devices (devices between the
source and destination devices). If the intermediate devices are HPE devices, execute the
ip
ttl-expires enable command on the devices. For more information about this command, see
Layer 3—IP Services Command Reference .
•
Enable sending of ICMP destination unreachable packets on the destination device. If the
destination device is an HPE device, execute the
ip unreachables enable command. For more
information about this command, see Layer 3—IP Services Command Reference .
For an IPv6 network:
•
Enable sending of ICMPv6 timeout packets on the intermediate devices (devices between the
source and destination devices). If the intermediate devices are HPE devices, execute the
ipv6
hoplimit-expires enable command on the devices. For more information about this command,
see Layer 3—IP Services Command Reference .
•
Enable sending of ICMPv6 destination unreachable packets on the destination device. If the
destination device is an HPE device, execute the
ipv6 unreachables enable command. For
more information about this command, see Layer 3—IP Services Command Reference .
Using a tracert command to identify failed or all nodes in a
path
Execute tracert commands in any view.
Task
Command
Display the routes from source
to destination.

For IPv4 networks:
tracert [ -a source-ip | -f first-ttl | -m max-ttl | -p port | -q
packet-number | -t tos | -vpn-instance vpn-instance-name
[ -resolve-as { global | none | vpn } ] | -w timeout ] * host
•
For IPv6 networks:
tracert ipv6 [ -f first-hop | -m max-hops | -p port | -q packet-number |
-t traffic-class | -vpn-instance vpn-instance-name [ -resolve-as
{ global | none | vpn } ] | -w timeout ] * host
For more information about the tracert mpls ipv4 command, see MPLS Command Reference .
Tracert example
Network requirements
As shown in Figure 3 , Device A failed to Telnet to Device C.
Test the network connectivity between Device A and Device C. If they cannot reach each other,
locate the failed nodes in the network.
