SLB (Auto-Fallback Disable)

The SLB (Auto-Fallback Disable) type of team is identical to the Smart Load Balancing™ and Failover type of team, with the exception of when the standby member is active, if a primary member comes back on line, the team continues using the standby member, rather than switching back to the primary member.

All primary interfaces in a team participate in load-balancing operations by sending and receiving a portion of the total traffic. Standby interfaces take over in the event that all primary interfaces have lost their links.

Failover teaming provides redundant adapter operation (fault tolerance) in the event that a network connection fails. If the primary adapter in a team is disconnected because of failure of the adapter, cable, or switch port, the secondary team member becomes active, redirecting both inbound and outbound traffic originally assigned to the primary adapter. Sessions will be maintained, causing no impact to the user.

Limitations of Smart Load Balancing™ and Failover/SLB (Auto- Fallback Disable) Types of Teams

Smart Load Balancing™ (SLB) is a protocol-specific scheme. The state of support for IP, IPX, and NetBEUI protocols is listed below.

The Smart Load Balancing™ type of team works with all Ethernet switches without having to configure the switch ports to any special trunking mode. Only IP traffic is load-balanced in both inbound and outbound directions. IPX traffic is load-balanced in the outbound direction only. Other protocol packets are sent and received through one primary interface only. Failover for non-IP traffic is supported only for network adapters. The Generic Trunking type of team requires the Ethernet switch to support some form of port trunking mode (for example, Cisco's Gigabit EtherChannel or other switch vendor's Link Aggregation mode). The Generic Trunking type of team is protocol- independent, and all traffic should be load-balanced and fault-tolerant.

`If you do not enable LiveLinkwhen configuring teams, disabling Spanning Tree Protocol (STP) at the switch is recommended. This minimizes the downtime due to the spanning tree loop determination when failing over. LiveLink mitigates such issues.
