BROADCOM ADVANCED SERVER PROGRAM OVERVIEW
Broadcom Advanced Server Program (BASP) is the Broadcom teaming software for the Windows family of operating
systems. BASP runs within the Broadcom Advanced Control Suite 3 (BACS) utility.
BASP provides support for TOE teaming only for NetXtreme II adapters.BASP supports four types of teams for Layer 2
teaming:
• Smart Load Balancing and Failover
• Link Aggregation (802.3ad)
• Generic Trunking (FEC/GEC)/802.3ad-Draft Static
• SLB (Auto-Fallback Disable)
BASP supports two types of teams for TOE teaming:
• Smart Load Balancing and Failover
• SLB (Auto-Fallback Disable)
NOTE: Enabling Windows Server 2003 built-in bridging is not advisable when you are using teaming software.
For more information on network adapter teaming concepts, see Broadcom Gigabit Ethernet Teaming Services.
LOAD BALANCING AND FAULT TOLERANCE
Teaming provides traffic load balancing and fault tolerance (redundant adapter operation in the event that a network
connection fails). When multiple Gigabit Ethernet network adapters are installed in the same system, they can be grouped
into teams, creating a virtual adapter.
A team can consist of two to eight network interfaces, and each interface can be designated as a primary interface or a
standby interface (standby interfaces can be used only in a Smart Load Balancing™ and Failover type of team, and only one
standby interface can be designated per SLB team). If traffic is not identified on any of the adapter team member connections
due to failure of the adapter, cable, switch port, or switch (where the teamed adapters are attached to separate switches),
the load distribution is reevaluated and reassigned among the remaining team members. In the event that all of the primary
adapters are down, the hot standby adapter becomes active. Existing sessions are maintained and there is no impact on the
user.
