Table 11-2 shows a summary of the teaming types and their classification.
Smart Load Balancing and Failover
The Smart Load Balancing and Failover type of team provides both load
balancing and failover when configured for load balancing, and only failover when
configured for fault tolerance. This type of team works with any Ethernet switch
and requires no trunking configuration on the switch. The team advertises multiple
MAC addresses and one or more IP addresses (when using secondary IP
addresses). The team MAC address is selected from the list of load balance
members. When the system receives an ARP request, the software-networking
stack will always send an ARP Reply with the team MAC address. To begin the
load balancing process, the teaming driver will modify this ARP Reply by changing
the source MAC address to match one of the physical adapters.
Smart Load Balancing enables both transmit and receive load balancing based on
the Layer 3 and Layer 4 IP address and TCP/UDP port number. In other words,
the load balancing is not done at a byte or frame level but on a TCP/UDP session
basis. This methodology is required to maintain in-order delivery of frames that
belong to the same socket conversation. Load balancing is supported on two to
eight ports. These ports can include any combination of add-in adapters and LAN
on motherboard (LOM) devices.
