7.5.1 Failure and recovery of member switch
- <Structure of this section>
(1) Master switch failure
The following figure shows the operation when a failure occurs in the master switch.
|
If the master switch fails and stops, the backup switch becomes the new master switch and operates on a single stack of the master switch. At this time, the device MAC addressis not changed.
(2) When the recovery master switch is restored
The following figure shows the operation when the recovery master switch recovers from a fault.
|
When the recovery master switch recovers from a failure, the member switch becomes a backup switch and operates on two member switches. At this time, the device MAC addressis not changed.
(3) In case of backup switch failure
The following figure shows what happens if the backup switch fails.
|
When the backup switch fails and stops, it operates on a single stack of the master switch. At this time, the device MAC addressis not changed.
(4) When the backup switch is restored
The following figure shows the operation when the backup switch recovers from a failure.
|
When the backup switch recovers from a failure, the member switch becomes a backup switch and runs on two member switches. At this time, the device MAC addressis not changed.
