z  To add a switch to a stack successfully, make sure the IP address pool contains at least one 
unoccupied IP address. 
z  Make sure the IP addresses in the IP address pool of a stack are successive so that they can be 
assigned successively. For example, the IP addresses in an IP address pool with its start IP 
address something like 223.255.255.254 are not successive. In this case, errors may occur when 
adding a switch to the stack. 
z  IP addresses in the IP address pool of a stack must be of the same network segment. For example, 
the 1.1.255.254 is not a qualified start address for a stack IP address pool. 
z  If the IP address of the management VLAN interface of the main switch (or a slave switch) is not of 
the same network segment as that of the stack address pool, the main switch (or the slave switch) 
automatically removes the existing IP address and picks a new one from the stack address pool as 
its IP address. 
z  Since both stack and cluster use the management VLAN and only one VLAN interface is available 
on the Switch 4200G switch, stack and cluster must share the same management VLAN if you 
want to configure stack within a cluster. 
Switching to Slave Switch View 
After creating a stack, you can switch to slave switch view from the main switch to configure slave 
switches. 
Table 1-2 Switch to slave switch view 
Operation  Command  Description 
Switch to slave switch view  
stacking number 
Required 
Number: Number of the slave 
switch to switch to. 
This command can be used to 
switch from user view of the 
main switch to user view of a 
slave switch. The user level 
remains the same while 
switching. 
 
You can quit slave switch view after slave switch configuration. 
Table 1-3 Quit slave switch view 
Operation  Command  Description 
Quit slave switch view 
quit 
You can quit slave switch view 
only by executing this 
command in user view of a 
slave switch. 
 
Slave Switch Configuration 
Just make sure the slave switch is connected to the main switch through the stack ports. No 
configuration is needed.
