Table 23 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 24 (page 60) shows the states of Interface:Port1 and Interface:Port2 when configured for
Link Aggregation Dynamic Mode.
