The S3100 series switches can be stacked only when stack modules are installed.
Stack Function Overview
A stack is a management domain formed by a group of Ethernet switches interconnected through their
stack ports. A stack contains a main switch and multiple slave switches.
Logically, you can consider a stack a single device and manage all the switches in a stack through the
main switch.
The Main Switch of a Stack
You can configure multiple Ethernet switches interconnected through their stack ports to form a stack by
performing configurations on one of the switches. In this case, the switch becomes the main switch of
the stack.
You can perform the following operations on a main switch:
z Configuring an IP address pool for the stack
z Creating the stack
z Switching to slave switch view
Before creating a stack, you need to configure an IP address pool for the stack on the main switch.
When adding a switch to a stack, the main switch picks an IP address from the IP address pool and
assigns the IP address to it automatically.
After a stack is created, the main switch automatically adds the switches that connected to its stack
ports to the stack. If a stack port connection is disconnected, the corresponding slave switch quits the
stack automatically.
The Slave Switches of a Stack
All the switches in a stack except the main switch are slave switches.
You can configure a slave switch in a stack on the main switch.
Creating a Stack
The following are the phases undergone when a stack is created.
