🔍 Use Traceroute Tool to Diagnose Network Issues

This topic describes how to use the Traceroute tool to trace routes to a specific hostname or IP address and includes traceroute test results.

Background Information

Traceroute is a network test tool that traces the gateways and locates paths taken from IZT Cloud Voice to a destination server and helps you detect network connectivity and locate network faults.

Procedure

1. Log in to PBX web portal, go to Maintenance > Troubleshooting > Traceroute.
2. In the Target Host field, enter the target hostname or IP address.
3. Click Start.

• The PBX starts to trace routes to the target domain or IP address.

4. The traceroute test is automatically completed when done.

Example 1: A good Traceroute

traceroute to www.google.com (142.251.177.30), 30 hops max, 60 byte packets
 1  192.168.7.1 (192.168.7.1)  1.671 ms  1.792 ms  2.054 ms
 2  192.168.1.1 (192.168.1.1)  6.472 ms  7.233 ms  8.020 ms
 3  10.240.13.65 (10.240.13.65) 12.881 ms 13.683 ms 14.419 ms
 4  72.14.199.128 (72.14.199.128) 17.168 ms 17.937 ms 18.658 ms
 5  * * *
 6  74.125.48.65 (74.125.48.65) 22.509 ms 13.948 ms 14.659 ms

The above example displays the format IP: Domain Host (Alphabet) and output time in milliseconds. Whenever a packet is passed between different nodes, the network is referred to as a hop.

Example 2: A failed hop

traceroute to www.google.com (142.251.177.30), 30 hops max, 60 byte packets
 1  192.168.7.1 (192.168.7.1)  1.671 ms  1.792 ms  2.054 ms
 2  192.168.1.1 (192.168.1.1)  6.472 ms  7.233 ms  8.020 ms
 3  * * *
 4  * * *
 5  * * *

In the above example, hops 1 and 2 respond, but hop 3 fails to respond. The traceroute fails at hop 3 due to a possible network issue and cannot identify the host.
