The FastLinQ SmartAN™
Link Speed
option sets the port to use Smart
Auto Negotiation. SmartAN is the default factory setting on the 41000 Series
Adapters. SmartAN provides the ability to automatically set up a link
between a 25G adapter and 10G switch over DAC and optics media without
user intervention or manual setup. The IEEE standards do not provide a
standards-based method to auto-negotiate between a 10G switch and a
25G adapter or between DACs and optics. Cavium’s SmartAN provides an
automatic and convenient method to detect the switch and to determine and
set the link speed, FEC types, media type and length, and so on. Although
SmartAN is most useful for connectivity with a 10G switch and for
determining the type of transceiver that is inserted in the adapter cage, it is
also useful for a wider set of connectivity use cases. The SmartAN link
speed is enabled on the 41000 Series Adapters, but you can select a
different link speed value in the HII console.
