address of the new primary adapter. As a result, some 
packets are dropped until the new primary adapter can 
reestablish connections using the new Ethernet address 
(possibly a 30-second or more delay). To disable receive 
load balancing and to improve fault tolerance, you must 
manually set the value of the Receive Load Balancing 
property to Off in the Advanced tab for the ALB team. 
(The ALB team continues to balance traffic that the team 
transmits.)
Static Link Aggregation Teams
Static link aggregation increases transmission and reception throughput by balancing 
both transmit and receive traffic over all members of the team. (Static link aggregation 
also includes AFT features.)
You must connect all members of a static aggregation team to a single switch that 
supports either the Fast EtherChannel (FEC) standard or the Gigabit EtherChannel 
(GEC) standard, and the relevant switch ports must be properly configured for it. When 
you create a static link aggregation team, it automatically negotiates a FEC or GEC 
connection, depending on the type and configuration of the switch.
 lists the types of static link aggregation teams that each Ethernet PCI adapter 
supports. See your switch documentation to determine which types of teams it 
supports.
IEEE 802.3ad Dynamic Link Aggregation Teams
IEEE 802.3ad Dynamic Link Aggregation teams provide full transmit and receive load 
balancing like the FEC and GEC standards, but in a dynamic-mode implementation. 
Dynamic mode is an implementation of the final 802.3ad specification.
Many switches support an implementation of only the draft 802.3ad specification, which 
does not include dynamic mode. To determine whether your switch is fully compatible 
with the dynamic-mode implementation of the 802.3ad standard, contact your switch 
vendor.
