Table 22 Link aggregation dynamic mode failover scenario and corresponding NIC status

NIC status

Example failover scenario

1. Link Aggregation Dynamic Mode bond0 is created.
Interface:Port1 and Interface:Port2 are both active.

Bond0 is the master logical interface.

Interface:Port1 is Active.

Interface:Port2 is Active.

2. Interface:Port1 interface fails. Because Link Aggregation
Dynamic Mode is configured, Interface:Port2 continues
operating.

Interface:Port1 status becomes Passive (Failed).

Interface:Port2 status remains Active.

3. Interface:Port1 link failure is repaired.

Interface:Port1 resumes Active status.

Interface:Port2 remains Active.

Summary of NIC states during failover

Table 23 (page 63)

shows the states of Interface:Port1 and Interface:Port2 when configured for

Link Aggregation Dynamic Mode.
