You can modify the following test parameters

• Subtest - The three options are Internal, Serdes, and External.

• Link Speed (HBA only) - For 8G adapter, 2G, 4G and 8G. For 4G adapter, 1G, 2G and 4G.

• Frame Count - Integer from 0 to 4,294,967,295. Default value is 8192.

• Data Pattern - Hex value. Default value is A5A5A5A5

5. Click Start.

Ethernet port loopback test (CNA only)

Use BCU commands and HCM to test the Ethernet data path from the host to serdes or external

loopback based on your selection. You must disable the port before testing and use a loopback

connector for the test.

NOTE

first created for the port.

Performing Ethernet loopback tests through HCM

Using the Ethernet Tests tab on the Diagnostics dialog box, you can set test parameters such as

external or serdes subtest, link speed, frame count, test cycle, and data pattern to test. Results

display on the bottom of the tab as the test commences.

1. Launch the HCM.

3. Click the Ethernet Tests tab.

4. Select Loopback Test.

Performing Ethernet loopback tests through BCU

Use the ethdiag --loopback command to run an Ethernet loopback test.

bcu ethdiag --loopback <port_id> [-t <loopback_type] [-c <frame_count>] [-p

pattern]

where:

port_id ID of the port for which you want to run the test.

-t loopback-type Specifies the loopback type. Possible values are serdes, and ext.
