Ethernet Controller Tests
The availability of Ethernet controller tests depends on the Enternet controller installed
in the server.
Data loop tests can add to network traffic. Consider disconnecting from the network
before running the data loop tests.

Estimated completion time
Description
MAC Address Verification
1 second
Verifies MAC address isn’t all FFs
or 00s.
MAC Loopback
1 minute
Verifies that there’s no data
mismatch between sent and
received data while looping
within the MAC (a sublayer of
the datalink layer in the ISO
network reference model).
PHY 1000 Loopback
20 seconds per port, 40 seconds
total
Verifies that there’s no data
mismatch between sent and
received data while looping
within the physical transport
medium (PHY) at 1000 Mbps.
PHY Jumbo Packet Loopback
25 seconds per port, 50 seconds
total
Verifies that there’s no data
