Preparing private interconnects for LLT
You must attach each network interface that is configured for LLT to a separate and distinct physical network.
Optimizing LLT media speed settings on private NICs
For optimal LLT communication among the cluster nodes, the interface cards on each node must use the same media speed settings. Also, the settings for switches or hubs used for the interconnects must match that of the interface cards. Incorrect settings can cause poor network performance or even network failure.
Guidelines for setting the media speed of the LLT interconnects
-
If you have hubs or switches for LLT interconnects, Symantec recommends using the Autonegotiation 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 Autonegotiation 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.
For details on setting the media speeds for specific devices, consult the device's documentation.
