Summary Of Nic States During Failover; Example Network Cabling Topologies With Adaptive Load Balancing - HP StoreVirtual 4000 User Manual

Table 23 Example Adaptive Load Balancing failover scenario and corresponding NIC status
Example failover scenario
1. Adaptive Load Balancing bond0 is created.
Motherboard:Port1 and Motherboard:Port2 are both active.
2. Motherboard:Port1 interface fails. Because Adaptive
Load Balancing is configured, Motherboard:Port2 continues
operating.
3. Motherboard:Port1 link failure is repaired.
