Note
Allied Telesis recommends leaving this value set to the default Auto
Negotiation. For the fiber versions of the DNC10, auto-negotiation
does not refer to traditional speed and duplex auto-negotiation that
is commonly used on copper-based NIC products. It simply means
that the NIC will automatically detect the speed of the fiber module
and set the controller's speed to match.
DNC10LC

Auto Negotiation - Link speed will be set to 10G

10G - Link speed is 10G per second
All other settings are invalid.
DNC10SP

Auto Negotiation - The NIC will auto-detect the SFP
speed and link speed will be set to 10G or 1G
accordingly

10G - Link speed is 10G per second

1G - Link speed is 1G per second
All other settings are invalid.
Note
The DNC10T uses standard auto-negotiation to determine link
speed in all cases. Forced speed is disallowed by IEEE 802.3 for
any speed of 1Gbps and above. When choosing a single speed from
the drop-down list, only that speed will be advertised by the NIC; if
the link partner does not also advertise the chosen speed, no link will
be established.
