3750G stack-switch reboot

Is there a way reboot a single switch in a stack configuration? After a power outage my switches reversed roles so my master became the slave and slave became master. I wanted to reboot only one switch so the remaining would assume the master role again.

You can use this command to reload a specific switch in the stack

reload slot xx

slot number is the switch number in the stack

Use "reload" command as explained by Reza above.

And if you want that switch to be the master all the time, set its priority to be highest (say 5). This way the desired switch will become master always.

Hi,

I believe stack master election will take place only if the reload command is issued from the master.

Ideally, the master will bootup first and it will wait for the other stack members to load inorder to form a stack.

Booting sequence:

checking for Bootloader upgrade.. not needed

Waiting for Stack Master Election...

So we need to set the priority of the switches and we need to reload the entire stack inorder to make our interested switch as master.

Setting a priority will not take into effect unless the master is reloaded.

you can perform a reload of the member using the below command as well

remote command reload

Hope this helps

Cheers
