z
When adding a switch joins in a stack, the main switch automatically assigns an IP
address to it.
z
The main switch automatically adds any switches that are newly connected to the
stack through their stack ports to the stack.
1.2 Main Switch Configuration
The main switch configuration includes:
z
Configuring the IP Address Pool and Creating the Stack
z
Maintaining Slave Switches
1.2.1 Configuring the IP Address Pool and Creating the Stack

Note:
Remove the IP address configured for the existing Layer 3 interface first if you want to
cancel the stack-related configuration, otherwise, IP address conflicts may occur.
As for the stack-related configurations performed on a main switch, note that:
z
After a stack is created, the main switch automatically adds the switches
connected to its stack ports to the stack.
z
If a stack port connection is disconnected, the corresponding slave switch quits
the stack automatically.
z
The IP address pool of an existing stack cannot be modified.
z
To add a switch to a stack successfully, make sure the IP address pool contains at
least one unoccupied IP address.
