Auto-stacking using LED mode button

Prerequisites

All switches must be in the factory default configuration.
All stack members must be connected in a ring topology on the reserved VSF link ports. For more information, see Reserved interfaces for auto-stacking.
Operator must be connected to the conductor’s USB-C console port or a terminal server connected to the USB-A port via a supported adapter or cable.

Procedure

Physically connect the switches in a desired topology on the reserved VSF link ports.
Press the LED mode button on the conductor until the mode changes to “Stk”. The stack members reboot one after another and join the stack.
During stacking operation, the port LEDs are displayed in three different states:
- Flashing green—Indicates that the member is the conductor.
- Flashing orange—Indicates that the member is rebooting to join the stack or offline due to error condition.
- Solid green—Indicates that the member joined the stack and is operational.
  For more information on stacking LED states, refer to the Monitoring Guide.
Issue a "show vsf" command to ensure that the stack has successfully formed. Alternatively, you can also verify the stack formation using LED states.
