I want to add 2 switches to my stack of 2.
Switch 1 is the top switch in rack and has a
priority of 15
Switch WS-C3750X-24P-S 2 the is second switch in rack and has
priority of 14
How can I configure the stack (provision
configuration) so that the 3rd switch in
rack will get switch number 3 and the 4th switch in rack gets number 4
All swiches are exact same module
Just
do one-by-one method with following configuration only from the stack master.
Switch(config)# switch 3 provision switch_PID -
put your 3rd switch into stack.
Verify the status of the provisioned switch.
For stack-member-number, enter the same number as in Step 1.
Switch(config)# switch 4 provision switch_PID -
put your 4th switch into stack.
Verify and save the config.
Note - switch_PID:
For type, enter the model number of a supported
switch that is listed in the command-line help strings.
change the stack member number by using the
switch <current-stack-member-number>
renumber <new-stack-member-number> global configuration command,
show swithc will show the current swithc number
and priority

the new number goes into effect after that
stack member resets (or after you use the reload slot stack-member-number
privileged EXEC command) and only if that number is not already assigned to any
other members in the stack.
A higher priority value for a stack member
increases its likelihood to be elected stack master and to retain its stack
member number. The priority value can be 1 to 15. The default priority value is
1. You can display the stack member priority value with the show switch user
EXEC mode command.

Cisco recommends that you assign the highest
priority value to the switch that you prefer to be the stack master. This
ensures that the switch is re-elected as stack master if a re-election occurs.
How do you change the priority value?
From
the global configuration mode, issue the command switch stack-member-number
priority new-priority-value .
From
the bootloader switch: prompt, issue the command set SWITCH_PRIORITY
new-priority-value .
Even though the priority value applies
immediately to the member, it will not affect the status of the current stack
master. New priority value will play a role in the next stack-master election.
Yes the switches will retain their numbers even
if you set different priorities.
The priority sets which switch in the stack
becomes the master. The number is just
that - the number of the switch WS-C3750X-24P-L in the stack. Once it's set the number won't change unless
you change it in the config.
