z
Connect the intended main switch and slave switches through stack modules and dedicated stack
cables. (Refer to H3C S3100 Series Ethernet Switches Installation Manual for the information
about stack modules and stack cables.)
z
Configure the IP address pool for the stack and enable the stack function. The main switch then
automatically adds the switches connected to its stack ports to the stack.
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.
Main Switch Configuration

Required
from-ip-address: Start address
of the IP address pool.
ip-address-number: Number of
the IP addresses in the IP
addresses pool.
ip-mask: Mask of the IP
address pool. The default mask
is 255.255.0.0.
By default, the IP addresses
pool is not configured.

Required
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.
