4-2DuraLAN Fast Ethernet NICs User’s GuideNote on DuraLAN NIC PortsWhen you are installing Adaptec DuraLAN NICs, it is a good ideato document where each port physically resides in the server,especially when two or more identical NICs exist. This is importantbecause ports are identified by generic port names.Port names are assigned to ports in the order that the system scansthese ports at boot time. Consequently, whenever you physicallyrearrange the network cards, the port names change as well.Note: Windows 2000 currently does not support SNMP.Configuring the Standalone Driver PortsGeneral Port Configuration in Windows OSsWindows 2000, which includes a GUI, supports dynamicunload/reload of drivers. Driver updates no longer require asystem reboot.Windows XP makes use of the same GUI used for Windows 2000—with enhanceents included for Windows XP.For each group of NICs, configure the property values (ConnectionTypes, Transmit Checksum Offload, Receive Buffers, ReceiveChecksum Offload, and Scatter Gather) to be the same. Forexample, within a group, do not set up one NIC with theconnection type as Autodetect and the other NIC’s connection typeas 100 Mbps. If you make changes to a group, be sure that all NICswithin the group have the same values.Standalone, Failover, Port Aggregation, and FEC can be configuredin mixed groups. For example, one NIC can be set up as Stand-alone, another group (two NICs) can be set up as Failover, andanother group of NICs can be set up as Port Aggregation. A totalnumber of 12 ports is supported for all configurations combined—with the exception of FEC, where a four-port maximum is allowed.Note: Only two or four ports can be configured with Cisco’sFEC.
