Chapter 4 Operations after OS Installation
Only a link down error between a LAN card (onboard LAN) and the switch it connects with, and the
equivalent errors lead to switching of the route. Therefore, if only the switch or LAN card (onboard
LAN) is partially damaged and the route being used is normal at the link level, the route will not be
switched in the team, but the communication using team may become an error.
Teaming types
Teaming has the following types.
Adapter Fault Tolerance (AFT)
Adapter Fault Tolerance (AFT) is a technology to make the link between the server and switches
redundant by using multiple LAN ports. When a failure occurs in the link being used (Primary Link), the
communication continues by switching the process to the standby link (Secondary Link) without
interrupting. For AFT, all ports in the team must be connected to the same switch.
Adaptive Load Balancing (ALB)
Adaptive Load Balancing (ALB) is a technology that distributes the sending and receiving data to
multiple LAN ports to improve the performance in addition to redundancy function of AFT (When
"Receive Load Balancing (RLB)" in Advanced setting is set to "Disabled", the reception is done only in
the Primary Link). For ALB, all ports in the team must be connected to the same switch as well as AFT.
Switch Fault Tolerance (SFT)
Switch Fault Tolerance (SFT) is a redundancy function equal in configuration to AFT when LAN ports
are connected to a separate switch. SFT switches the link to be used between LAN ports and switches
that are connected to the LAN ports when a failure occurs. However, a failure in links outside of the
switches (

FEC/GEC Generic Trunking
Select this mode when connecting a team to a Cisco FEC/GEC compliant switch or a switch that
supports IEEE802.3ad-Draft Static. Switch settings are also necessary. All ports in the team must be
connected to the same switch.
