After you install a stack card and power on the switch, you can configure related software on the switch. Available configuration options include configuring a stack ID, and configuring a stack priority. By default, the stacking function is enabled on a switch, and you are advised to configure a stack ID and a stack priority to facilitate management. You can configure stack software on a switch that uses stack card stacking with stack ports fixed on the rear panel after the switch is powered on, without having to install stack cards on the switch.
The configuration takes effect after the switch is restarted.
By default, the stack priority of a member switch is 100.
