Table 23 Link aggregation dynamic mode failover scenario and corresponding NIC status
NIC statusExample 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 24 (page 60) shows the states of Interface:Port1 and Interface:Port2 when configured for
Link Aggregation Dynamic Mode.

Example network cabling topologies with link aggregation dynamic mode
A simple network configuration using Link Aggregation Dynamic Mode in a high-availability
environment is illustrated in Figure 39 (page 61).
