Enabling a Port Indicator to Show the Stack ID

Enabling a Port Indicator to Show the Stack ID


The master switch can assign stack IDs to member switches once a stack is established. You can also configure stack IDs for member switches. If stack IDs are assigned by the master switch, it is difficult to match a stack ID with a corresponding member switch. In this case, you can enable a port indicator to show the stack ID of a member switch.

When checking the stack ID of a member switch, note the following:
  • Switch with a stack ID ranging from 1 to 8: The sequence number of the port indicator that is steady on indicates the stack ID of the switch. For example, if the first port indicator is steady on, the stack ID is 1. If the second port indicator is steady on, the stack ID is 2.
  • Switch with stack ID 0: If the first nine port indicators are steady on, the stack ID of the local switch is 0.
  • After port indicators are configured to show the stack IDs, the port indicator of the master switch blinks, and the port indicator of the slave switch is steady on.

On the S5700-28X-LI-24S-DC, S5701-28X-LI-24S-AC, and S5700-28X-LI-24S-AC, if a physical port is shut down by the shutdown command or by the MAD mechanism after the CSS splits, the corresponding port indicator is off and cannot indicate the stack ID of the local switch.


  1. Run the stack led enable [ duration duration-value ] command to enable port indicators to show stack IDs of member switches.

    By default, port indicators do not show stack IDs of member switches.


    This command can be executed only when the MODE button is not pressed on the switch to change the indicator mode.

    The configuration of this command becomes invalid when port indicators show stack IDs of member switches for the specified time.
