How Do I Remove All Stack Configuration from 3750's?

I had two 3750's stacked and now I want to have each on of them as a standalone switch.  I removed the Stackwise cable but each time they boot up separately now they think they still should be part of the original stack. 


How can I remove all stack configurations from each one?


Thank you,


Thomas

Hi Thomas,


You don't need to to erase the configuration - you can just switch off  the stack member you wish to remove, and then unprovision it using the  command:


no switch provision


Example:


To remove switch number 2 from a stack. The model number of the switch  is WS-C3750G-48T:


3750(config)# no switch 2 provision ws-c3750g-48t

3750(config)# exit

3750# write memory


Please check this.

Console into switch #2 and do the following:


1.  switch 2 renumber 1

2.  Delete config.text and vlan.dat files.  Don't forget to delete the backup files too.

If a switch stack runs Cisco IOS Release  12.2(20)SE or later and you remove a provisioned switch from the switch  stack, the configuration associated with the removed stack member  remains in the running configuration as provisioned information. In  order to delete all configuration information associated with the  removed switch (a stack member that has left the stack), apply the no switch provision command in global configuration mode.


As mentioned by Amit, use these commands.


3750(config)# no switch 2 provision ws-c3750-48ts
3750(config)# exit
3750# write memory
