Route Analysis Topology
Tracert enables retrieval of the IP addresses of Layer 3 devices in the path to a specific destination. In the event of network failure, use tracert to test network connectivity and identify failed nodes. The route analysis topology shows the tracert result. If an intermediate device is managed by the system, the device type is displayed in the topology. Otherwise, the device is displayed as an unknown device.
The next hop address and the tracert time are displayed on each link. The device name and device IP address are displayed on each node. The message box at the bottom also displays the next hop and the tracert time.
Operation Procedure
Use the route analysis function in one of the following methods:
- Select two devices in the IP topology, Layer 2 topology, or custom topology, right-click any of the two devices, and select Analyze Route from the shortcut menu.
- Right-click the blank space in the IP topology, Layer 2 topology, or custom topology, and select Analyze Route from the shortcut menu. On the dialog box that appears, specify the source IP and destination IP, and click OK to enter the route analysis topology.
Precautions
- For a device, its IP address managed in the system platform might be different from its IP address during the tracert operation. As a result, the IP address displayed on a topology node might be different from the next hop address displayed on the corresponding link. This condition is normal.
- In an IPv4 network: You must configure the intermediate devices (devices between the source device and the destination device) to send ICMP time exceeded packets. If an intermediate device is an UNIS or Intelbras device, you must execute the ip ttl-expires enable command on the device. You must configure the destination device to send ICMP destination unreachable packets. If the destination device is an UNIS or Intelbras device, you must execute the ip unreachables enable command on the device.
Parameters
- Source IP: IP address of the source device.
- Destination IP: IP address of the destination device.
