NVM Speed
Sets the default speed mode used by the port. Not all speed modes are
available on each adapter.
AutoNeg: Sets the speed to AutoNeg mode.
1G: Sets the speed to 1GbE fixed link speed.
10G: Sets the speed to 10GbE fixed link speed.
25G: Sets the speed to 25GbE fixed link speed.
40G: Sets the speed to 40GbE fixed link speed.
50G: Selects 50GbE fixed link speed.
100G: Sets the speed to 100GbE fixed link speed.
Smart AN Mode
Enables (1) or disables (0) SmartAN mode. Generally, for SmartAN mode to
work, 29/31 (and 67 for the preboot link speed used for PXE/iSCSI/FCoE
boot) must be set to AutoNeg mode (0). If Smart AN Mode is enabled, the
NVM Speed setting is automatically set to AutoNeg.
FEC Force Mode
Sets the FEC mode forced on when a fixed speed mode is enabled. Not all
FEC modes are available on each adapter.
None: No FEC mode is used.
FC: FC-FEC mode is used.
RS: RS-FEC mode is used.
Auto: The port will cycle through the applicable FEC modes for the
selected fixed speed mode enabled until a link is established.
key=value
Specifies a physical port device key and value. The key and value are case
insensitive and must be specified within double quotes if they contain any spaces
or special characters. Do not include spaces around the = (equal sign).
Notes Only the applicable properties are shown in the command output. For example, if
SmartAN is set to 0 (disabled) and NVM Speed is set to AutoNeg, FEC AN Mode
is shown but FEC Force Mode is not shown.
