By default Supermicro switches act as standalone switches. This standalone default facilitates using 
10G Ethernet ports as Extreme Ethernet ports for 10G uplinks. When stacking is enabled the stacking 
ports are dedicated for stacking traffic.   
 
Stacking can be enabled using the command “

stack

” with a switch identifier and priority. See below: 

 

SMIS# stack priority PM switchid 1 ports xg1,xg2 
After enabling stacking, switch will be reloaded immediately. 
Do you really want to execute this command and reload the switch? [y/n] 

 

 
This example turns on stacking on the specified switch with Preferred Master priority and switch ID 1 
and also assigns xg1 and xg2 as stacking ports.   
 
To disable stacking on the specified switch, just use the “no stack” CLI command. After reboot, the 
switch will be configured in standalone mode.   
 

SMIS# no stack 
After removing from stacking, switch will be reloaded immediately. 
Do you really want to execute this command and reload the switch? [y/n] 

 

 
If a user chooses stacking using the “

stack

” command from the non-stacking state and if the 

configurations are already saved for restore,the switch will rename the configuration file by adding a 

suffix _nonstack

 and will not restore this file when the switch reboots with stacking enabled. 

 
Similarly, if a user chooses non-stacking using the “

no stack

” command from a stacking state and if 

the configurations are already saved for restore, the switch will rename the configuration file by adding 

suffix _stack

 and will not restore this file when the switch reboots with stacking disabled.
