3750 switch master command

Hi All,


I'm sending out a quick question to verify that there is no command to manually cause a member switch to become master.  The only way to change the master is by reloading it.  Is this correct?


I know I can change switch priorities and influence which switch will become master when I reload the entire stack but there doesn't appear to be a way to change masters in a running stack without a reload.


Thanks,

Bruno

Master will be re-elected when


  • When the whole switch stack is reset1

  • When the stack master is reset or powered off

    Note: If you reset the stack master, it would reset the whole stack.

  • When the stack master is removed from the stack

  • When the stack master switch has failed

  • The switch stack membership is increased by if you add powered-on standalone switches or switch stacks.1


So your understanding is correct that you cannot make other switch master till you reload the stack...
