Default value is A5A5A5A5. 5. Click Start. Ethernet port loopback test (CNA) Run Ethernet loopback tests on CNA ports and Fabric Adapter ports configured in CNA or NIC mode. Use BCU commands and HCM to test the Ethernet data path from the host to serdes or external loopback based on your selection. For mezzanine or expansion card adapters, this test can be performed using a pass-through module.You must disable the port before testing and use a loopback connector for the test. NOTE For 64-bit platforms only, you cannot perform Ethernet loopback tests on the port unless a VLAN is first created for the port. Performing Ethernet loopback tests through HCM Using the Ethernet Tests tab on the Diagnostics dialog box, you can run Ethernet loopback tests and set test parameters such as external subtests, serdes subtests, link speed, frame count, test cycle, and data pattern to test.
