speed
For HBAs and Fabric Adapter ports configured in HBA mode only. For a 4 Gbps
port, this is 2 or 4. For an 8 Gbps port, this is 2, 4, or 8. For a 16 Gbps port,
this is 4, 8, or 16.
frame count
Integer from 0 to 4,294,967,295. Default is 8192.
-p pattern
Hex number. Default value is A5A5A5A5.
Performing loopback tests through HCM
Use the Hardware Tests tab on the Diagnostics dialog box to perform a loopback test.
1. Launch the HCM.
2. Select Configure > Diagnostics.
3. Click the Hardware Tests tab.
4. Select Loopback Test.
You can modify the following test parameters:
•
Subtest - The three options are Internal, Serdes, and External.
•
Link Speed (HBAs and Fabric Adapter ports configured in HBA mode) - For 16G ports, 4G,
8G, or 16G. For 8G ports, 2G, 4G, and 8G. For 4G ports, 1G, 2G, and 4G. For 4G ports, 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)
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. Results display on the bottom of the tab as the test commences.
1. Launch the HCM.
2. Select Configure > Diagnostics.
3. Click the Ethernet Tests tab.
4. Select eth Loopback Test.
