After a stack is set up, you can observe indicators on member switches or use commands to determine which member switch is the master switch.

  • Observing indicators

    If the MST indicator on a switch is steady green, the switch is the master switch. The MST indicators on the other member switches are off, and the switches are standby or slave switches.

  • Using commands

    Run the display stack or display device command to check which member switch is the master switch.
