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 S3100 switch, stack and cluster must share the same management VLAN if you want to
configure stack within a cluster.
Maintaining Slave Switches
After creating a stack, you can switch to slave switch view from the main switch to configure slave
switches.
Operation Command Description
Switch to slave switch view stacking number
Required
Number: Serial number of the
slave switch to be accessed.
You can switch from the user
view of the main switch to that
of the slave switch without
changing the user level.
You can quit slave switch view after slave switch configuration.
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.
Stack-Port Function Configuration
On the S3100 series switches, only GE SFP ports that are installed with stack modules can be used as
stack ports.
