this case, the active/standby switchover is implemented on the stack system where the standby
switch belongs. After the active/standby switchover, the new master switch specifies the MAC
address of its own as the MAC address of the stack system. In addition, the new master switch
sends gratuitous ARP packets to instruct other switches to update their MAC address and
implements IP collision detection. It is required that the two newly-created stack systems be able
to receive gratuitous ARP packets. After the original stack system is divided, the original master
switch detects IP address collision if receiving gratuitous packets whose source IP address is the
same as the IP address of the master switch. At the same time, the original master switch keeps
sending gratuitous ARP packets until no ARP packet with the conflicted IP address is received.

After a stack system is created, the entire stack system logically functions as one switch. The
features supported by stacking are configured the same whether in a stack system or in a non-
stack system. For more details, see the related configuration guide.
