76CHAPTER 4: INSTALLING DYNAMICACCESS SOFTWARE IN WINDOWS

Configuring Offloads for a Group of Different NICs

Your computer may contain a combination of installed NICs (including one or more 3CR990 EtherLink 10/100 PCI NICs with the 3XP Processor) with varying offload capabilities. If you have a mix of dissimilar NICs configured in a DynamicAccess group, then DynamicAccess will support only those offload functions that are supported by the all the NICs in the group.

For example, if you have created a group consisting of a 3CR990 NIC and another NIC that does not have any offload capabilities, then the group will not support any offloads.

In another example, if you have a group of three NICs with two supporting TCP Checksum, TCP Segmentation, and IPSec offloads, and one supporting only IPSec, then the group will support only IPSec offloads.

If you add a NIC to an existing group, and that NIC has offload capabilities that differ from those of the group, then you must reconfigure the group: that is, you must delete the group, recreate the group, and restart the computer. (If you do not delete and recreate the group, DynamicAccess will not bind to the NIC.)

Similarly, if you replace a NIC that has been configured as part of a group with another NIC that has different offload capabilities, then you must reconfigure the group.

In addition, if you disable or enable any offloads for a group through the Windows 2000 Advanced tab, then you must reconfigure the group.
