3750 Stack Master Election

cindylee27 · ‎11-05-2007

Hi Experts,

Trying to understand 3750 Switching concept.. How does the stack master being elected?

I read in the internet, that it selected by the lowest MAC-Address but when I boot up,it choosen the highest one..

And can it be manually done?

Thanks,

This is how to do it manually:

Use the switch priority global configuration command on the stack master to change the stack member priority value:

switch stack-member-number priority new-priority-value

Usage Guidelines

The new priority value is a factor during a stack-master re-election. Therefore, changing the priority value does not change the stack master immediately.

This example shows how to change the priority value of stack member 6 to 9:

Switch(config)# switch 6 priority 9

To the first part of your question - the first switch in the stack booted, is the master ( if I remember correctly ).
