Ethernet diagnostics
The Ethernet loopback test generates and sends out the desired number of packets and expects to
receive the same number of packets through the loopback interface (Serdes or external). Each
time a packet is sent it is selected from a different starting point of the data buffer so that any two
consecutively transmitted packets will not be the same.
You must have the Ethernet card and the device driver installed and a loopback connector in place.
The loopback connector is a standard RJ-45 connector.
NOTE
Windows 64-bit platforms only: You must first create a VLAN on the port before you perform an
Ethernet loopback test. If the port does not have a VLAN, an error message displays.
The following procedure explains how to run an Ethernet test.
1. Select an Ethernet port from the device tree.
2. Select Configure > Diagnostics from the main menu.
OR
Right-click the component and select Diagnostics from the list.
The Diagnostics dialog box is displayed.
3. Click the Ethernet Tests tab.
