Configuring stack 

Overview 

The stack management feature enables you to configure and monitor a group of connected switches by 

logging in to one switch in the stack, as shown in 

Figure 28

. 

Figure 28

 

Network diagram 

 

 

To set up a stack for a group of connected switches, you must log in to one switch to create the stack. This 
switch is the master switch for the stack, and you configure and monitor all other member switches on the 

master switch. The ports that connect the stack member switches are called stack ports. 

Configuration task list 

Task Remarks 

Configuring the master device of a stack:

 

 

Configuring global stack parameters 

Required. 
Configure a private IP address pool and set up the stack.  
By default, no IP address pool is configured for a stack and no 
stack is set up. 

Configuring stack ports 

Required. 
Configure the ports connected to member devices as stack 
ports. 
By default, no ports are configured as stack ports. 

Configuring stack ports 

Required. 
Configure ports connected to the master device or other stack 
member devices as stack ports.  
By default, no ports are configured as stack ports.
