Configuring the Stack Competition Delay

Configuring the Stack Competition Delay


During a stack restart, the startup time of member switches varies. If the startup time difference is large, the master, standby, and slave roles may change or some member switches restart multiple times. Assume that three switches A, B, and C set up a stack in chain topology and switch B starts slowly. After the stack restarts, switches A and C finish starting first and compete to be the master switch, whereas switch B has not finished starting. After switch B finishes starting, switches A and C perform stack competition. The switch that fails stack competition restarts again and then joins the stack.

To prevent this problem, before the stack restart, configure the stack competition delay for the switches that start quickly so that stack competition begins after the switch that starts slowly finishes starting.


  1. Run the system-view command to enter the system view.
  2. Run the stack command to enter the stack management view.
  3. Run the stack member member-id competition-delay delay-time command to configure the stack competition delay.

    By default, the stack competition delay is 0 seconds.

  4. Run the commit command to commit the configuration.
