Whether USG firewalls support the stacking feature
USG firewalls do not support the clustering or stacking function. You can configure hot standby to improve reliability.

Whether S series fixed switches support stacking
The Typical Configuration Examples document describes whether each model and version of S series fixed switches (except S1700 switches) supports stacking as well as stack modes, hardware and software requirements, typical networking, and configuration steps. For details, click Typical Configuration Examples and choose Typical Stack Configuration of Fixed Switches- Determining the Stack Connection Mode and Hardware and Software Requirements.

Whether the configuration of an S series fixed switch stack changes after the stack splits
After a stack is set up, all stack member switches function as one switch on a network. The configuration of the stack is the configuration of the master switch, which is synchronized to the standby switch by the master switch. If a fault occurs on the master switch and the master switch restarts, the standby switch does not restart and function as the master switch. That is, the configuration of the stack does not change.
