different switches and one of the switches fail, the team remains available via the group attached to the functional switch. Switch-assisted Dual Channel Load Balancing is an advanced feature of HP Integrity Network Adapter Teaming. Refer to "Basic Teaming Versus Advanced Teaming" for more information. 802.3ad Dynamic Dual Channel Load Balancing 802.3ad Dynamic Dual Channel Load Balancing, referred to as Dynamic Dual Channel, is identical to Dual Channel except that the switch must support the IEEE 802.3ad dynamic configuration protocol called Link Aggregation Control Protocol (LACP). In addition, the switch port to which the teamed ports are connected must have LACP enabled. The main benefits of Dynamic Dual Channel are that an SA will not have to manually configure the switch and will not have to manually assign teamed ports to individual groups (A or B). Dynamic Dual Channel utilizes the 802.3ad Link Aggregation Protocol to automatically determine which teamed ports are connected to common switches. Dynamic Dual Channel will then dynamically create Port Trunk (channels) for those "switch port to team port" combinations. 802.3ad Dynamic Dual Channel Load Balancing is an advanced feature of HP Integrity Network Adapter Teaming. Refer to "Basic Teaming Versus Advanced Teaming" for more information. Automatic The Automatic team type is not really an individual team type. Automatic teams decide whether to operate as an NFT or a TLB team or as an 802.3ad Dynamic team. If all teamed ports are connected to a switch that supports the IEEE 802.3ad Link Aggregation Protocol (LACP) and all teamed ports are able to negotiate 802.3ad operation with the switch, then the team will choose to operate as an 802.3ad Dynamic team. However, if the switch doesn't support LACP or if any ports in the team don't have successful LACP negotiation with the switch, the team will choose to operate as a TLB team. As network and server configurations change, the Automatic team type ensures that HP Integrity servers intelligently choose between TLB and 802.3ad Dynamic to minimize server reconfiguration. Automatic is a basic feature of HP Integrity Network Adapter Teaming. Refer to "Basic Teaming Versus Advanced Teaming" for more information. How to Choose the Best Team Type There are several important decisions that need to be made when choosing the team type to use when deploying HP Integrity Network Adapter Teaming (refer to Figure 3-5). 20 Teaming Fundamentals for the First-Time User

802.3ad Dynamic Dual Channel Load Balancing
802.3ad Dynamic Dual Channel Load Balancing, referred to as Dynamic Dual Channel, is identical
to Dual Channel except that the switch must support the IEEE 802.3ad dynamic configuration
protocol called Link Aggregation Control Protocol (LACP). In addition, the switch port to which
the teamed ports are connected must have LACP enabled. The main benefits of Dynamic Dual
Channel are that an SA will not have to manually configure the switch and will not have to
manually assign teamed ports to individual groups (A or B). Dynamic Dual Channel utilizes the
802.3ad Link Aggregation Protocol to automatically determine which teamed ports are connected
to common switches. Dynamic Dual Channel will then dynamically create Port Trunk (channels)
for those “switch port to team port” combinations.

Automatic
The Automatic team type is not really an individual team type. Automatic teams decide whether
to operate as an NFT or a TLB team or as an 802.3ad Dynamic team. If all teamed ports are
connected to a switch that supports the IEEE 802.3ad Link Aggregation Protocol (LACP) and all
teamed ports are able to negotiate 802.3ad operation with the switch, then the team will choose
to operate as an 802.3ad Dynamic team. However, if the switch doesn’t support LACP or if any
ports in the team don’t have successful LACP negotiation with the switch, the team will choose
to operate as a TLB team. As network and server configurations change, the Automatic team
type ensures that HP Integrity servers intelligently choose between TLB and 802.3ad Dynamic
to minimize server reconfiguration.
