How to Enable Traceroute on HPE Routers and Switches

Traceroute in HPE Devices

Maintaining a healthy network requires constant vigilance. When troubleshooting connectivity issues, pinpointing the exact location of the problem becomes critical. Here, traceroute emerges as a powerful tool. While HPE routers and switches lack a built-in tracert command, fear not! We can achieve by enabling essential features.

Step1:Log in to the router/switch CLI.

Commands to Enable the Features:

system-view
ip unreachables enable
ip ttl-expires enable

Step2:Save the configuration.

Once you have enabled tracert, you can use the following command to trace the route to a destination:

tracert destination_ip_address

For example, to trace the route to the IP address 192.168.1.1, you would use the following command:

tracert 192.168.1.1

The tracert command will output information for each hop between the router/switch and the destination address. This information includes the hop number, the IP address of the router, and the round-trip time (RTT) for the hop.

If the tracert command fails to reach the destination address, there are several possible reasons:

• The destination address is unreachable.
• The tracert packets are blocked or rejected by a router in the path.
• There is a problem with the network infrastructure between the router/switch and the destination address.

Conclusion

Although HPE routers and switches don't have a native tracert command, enabling the functionalities outlined above empowers you to gain valuable insights into your network's path. With traceroute at your disposal, troubleshooting network connectivity becomes a more efficient and targeted process, ensuring a smoothly functioning network.
