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.
