The kinds of the LAN advanced functions and the ways to set the LAN advanced functions
are explained in this chapter.
It's necessary that you insall "Intel (R) PROSet" to use the LAN advanced
functions. On Windows Server 2012, use the NIC teaming function which is an
original function provided by Windows Server 2012.
The available functions (teaming, tag-VLAN) are shown below.
Adapter Fault Tolerance (AFT)
Combines two LAN devices and, if a network connection error occurs, automatically
Feature failover to a backup LAN device. The function ensures the network redundancy and
fault tolerance.
-Connected HUB: Switching HUB
-Two LAN devices must be connected to the same switching HUB. The spanning tree
Condition
protocol (STP) must be disabled for the switching HUB.
-Supported protocol: IP
Adaptive Load Balancing (ALB)
Combines two LAN devices and distributes the traffic load on transmission data to
Feature
the devices. The function enhances the network bandwidth.
-Connected HUB: Switching HUB
-Two LAN devices must be connected to the same switching HUB. The spanning tree
Condition
protocol (STP) must be disabled for the switching HUB.
-Supported protocol: IP
Switch Fault Tolerance (SFT)
Combines two LAN devices with two switching HUBs (active and standby)
Feature corresponding to STP (IEEE802.1d). The function ensures the redundancy of LAN
devices and switching HUBs and provides the highly reliable network.
-Connected HUB: Switching HUB compliant with IEEE802.1d STP
-Two LAN devices must be connected to different switching HUBs. The spanning tree
Condition protocol (STP) of the switching HUB port must be enabled. But the STP must be
disabled for the Switching HUB port to be connected to the LAN device.
-Supported protocol: IP
TagVLAN IEEE802.1q VLAN
Identifies a VLAN group based on ID specified for the tag in the packet and provides
Feature
the logical segmentation.
-Connected HUB: Switching HUB compliant with IEEE802.1q VLAN
Condition -Available groups: Up to ten groups (ID: 1-4094) per system
-Supported protocol: IP
2-2
