Failover Teaming

Failover Teaming provides a redundant adapter operation in the event that a network connection fails. When multiple Gigabit Ethernet Adapters are installed in the same server, they can be paired into teams. Each team must have at least one adapter, but can support up to eight adapters. The number of teams is limited by the number of adapters that are installed.

If the primary adapter in a team is disconnected because the adapter, cable, or switch port fails, the secondary team member becomes active. In this case, the secondary team member redirects both the inbound and outbound traffic originally assigned to the primary adapter. Sessions are maintained; consequently, there is no impact to the user.

Note

Allied Telesyn recommends disabling STP when you use the teaming and fault tolerance features.
