Using the 3750 as a non-stack switch..how to set it up?

[RabbitSF]

Currently we have two WS-C3850-24P work as our core switches and connected with 6 other WS-C2960X-48FPS-L across our school LAN.

I recently got 4 used WS-C3750-48PS-S switches and thought I could use them as backup in case the 2960X crashes. The question is if this is workable? If yes, how to configure from the CLI? I already reset the 3750 to factory default. Any command I need to run to clear anything else? Anything else that I need to be aware of?

Or simply put, can I make the 3750 work as a 2960x? and how?

I am not a pro on Cisco switches so forgive me if that sounds to be a stupid question. Thanks much!

Yes. it's good to go. but I am curious if this is related to bug CSCsj80738. Please post show version.

Hit switch(config)#no switch 7 provision then upgrade your code to release 12.2.55-SE11 "c3750-ipbasek9-mz.122-55.SE11.bin". Everything should be good.  

[RabbitSF]

Sure. I will give it a try. Thanks so much for being with me and giving all the instructions. I will update you when I am done updating the image.

The switch should work stand-alone as member seven, but if the no switch 7 provision doesn't do the trick, you might also try switch 7 renumber 1.

[RabbitSF]

Yes, I renumber it to 1, update the image to the latest which is c3750-ipbasek9-mz.122-55.SE11.bin. 

I now have the following,

Switch#show switch

Switch/Stack Mac Address : 0026.0ae9.ca80

                                           H/W   Current

Switch#  Role   Mac Address     Priority Version  State

----------------------------------------------------------

*1       Master 0026.0ae9.ca80     1      0       Ready

And show version gives the following,

Switch Ports Model              SW Version            SW Image                 

------ ----- -----              ----------            ----------               

*    1 52    WS-C3750-48P       12.2(55)SE11          C3750-IPBASEK9-M 

So I believe that's it. What I am going to do next is to set up some basic configuration and then plug to the LAN to see how it goes. Thanks much!

Cool. Please don't forget to rate/mark as correct answer :)

I also found this post on this forum,

It seems there is no way to get rid of the stack configuration.
