Figure 5-4 Port Loopback Test Window
To run the internal, external, or online port loopback test on a port, do the
following:
1. In the faceplate display, select the port to be tested.
2. Open the Port menu and select Port Loopback Test to open the Port
Loopback Test window.
3. In the Test Selection area, choose the radio button for the type of loopback
test to be run (Internal, External, or Online). If you choose the internal or
external test, SANbox Manager will prompt you to confirm that the port state
needs to be changed to the diagnostic state. Choose the OK button and
SANbox Manager will change the port state.
4. Enter the frame count, frame size, and choose a test pattern radio button.
You may use the default pattern or enter an 8-digit pattern (hex). For online
test, you can select the Terminate Test Upon Error check box if you want
the test to stop should it encounter an error.
Note: The SerDes (Internal) and SFP (External) level tests disrupt
communication on the selected port. The Node-to-Node (Online) level
test does not disrupt communication, because the requires that the port
be online.
