If you have hubs or switches for LLT interconnects, Symantec recommends using the Auto_Negotiation media speed setting on each Ethernet card on each node.
If you have hubs or switches for LLT interconnects and you do not use the Auto_Negotiation media speed setting, set the hub or switch port to the same setting as that used on the cards on each node.
If you use directly connected Ethernet links (using crossover cables), set the media speed to the highest value common to both cards, typically 100_Full_Duplex.
Symantec does not recommend using dissimilar network cards for private links.
Details for setting the media speeds for specific devices are outside of the scope of this manual. Consult the device's documentation for more information.
