I was asked to stack some few Cisco 2960S switches for a site.
You can stack 2 or more switches (depending on the switch platform) using the Cisco FlexStack module and cable. The StackWise technology is used by Cisco 3750 switches.
Switch(config)#switch ?
<1-4> Switch Number // 2960S CAN STACK UP TO 4 SWITCHES
Switch(config)#switch 1 ?
priority Set the priority of the specified switch
provision Configure Switch provision / offline config
renumber Renumber the specified switch number
Switch(config)#switch 1 priority ?
<1-15> Switch Priority
Switch(config)#switch 1 priority 15
Changing the Switch Priority of Switch Number 1 to 15
Do you want to continue?[confirm]
New Priority has been set successfully
Switch(config)#switch 2 priority 12
There is no switch number 2 in the stack // CAN ONLY ACTIVATE THIS COMMAND ONCE FLEXSTACK MODULE/CABLE IS CONNECTED
Switch(config)#switch 3 priority 10
There is no switch number 3 in the stack
Switch(config)#switch 2 priority 12
Changing the Switch Priority of Switch Number 2 to 12
Do you want to continue?[confirm]
New Priority has been set successfully
Switch(config)#switch 3 priority 10
Changing the Switch Priority of Switch Number 3 to 10

You can pre-configure ports on member switches using the switch x provision y command. You can stack a Cisco 2960S 24-port together with a 48-port switch.
I needed this command since the VLANs and ports on our 2960S switches were already configured. Once stacking is done and switches are rebooted, our VLAN 1 management IP address on member switches were gone. The config on the master switch remained intact.
Switch(config)#switch 2 provision ?
