h3cStackMacPersistence 1.3.6.1.4.1.43.45.1.10.2.91.1.5

The mode of bridge MAC address persistence. When a stack starts, the bridge MAC address of master board will be used as that of the stack. If the master board leaves the stack, the bridge MAC address of the stack will change based on the mode of bridge MAC address persistence. notPersist: The bridge MAC address of the new master board will be used as that of the stack immediately. persistForSixMin: The bridge MAC address will be reserved for six minutes. In this period, if the master board which has left the stack rejoins the stack, the bridge MAC address of the stack will not change. Otherwise, the bridge MAC address of the new master board will be used as that of the stack. persistForever: Whether the master leaves or not, the bridge MAC address of the stack will never change.
