[Problem Description]
After IP address flapping is configured, services cannot be restored after the standby ports are recovered.
[Symptom Description]
The four Ethernet ports on controller A form the port group bond0, and the four Ethernet ports on controller B form the write port group bond1. Create logical port lif01 on bond0 and set the port to automatically drift to bond1.
Controller B of bond1 is faulty, and controller A of bond0 is also faulty. The logical port lif01 is down. Controller A of Bond0 does not recover, and controller B of Bond1 recovers. However, the logical port is still down and services cannot be restored.
[Cause]
In the IP address flapping function, when the bound port of controller B recovers, the bound port of controller A does not switch the logical port address.
[Location Method]
1. View log events.
2. The interface fault sequence is as follows: The bound interface of controller B is Down.
3. The bound interface of controller A is Down.
4. The bound port of controller B recovers to the Up state.
[Solution]
1. Manually set the primary port of the logical port to bond1 of controller B. The logical port can be restored to Up.
