Best practice for adding new S3500 switches to mobility access switch stack
03-01-2015 02:41 PM
I have a number of questions regardiing the S3500 switch in stack configuration.
1. What is the maximum number of switches in a single switch stack comprising S3500 switches?
2. And can you add a new S3500 switch with a different software version to that of the existing switch stack?
3. Lastly, will the switch stack retain all the original configuration when new switches are added to the stack?

1) 8 switches in a stack (0-7). If you need more than 8, you can create a "sub-stack" which a separate stack that is L2 connected to the main stack (you can use DAC cables at 10G, they will be switchports instead of stacking ports). Just don't add too many or you risk exceeding the MAC tablesl
2) You can add the switches, but they will remain dormant until you upgrade the code.
3) Yes, the primary (which is one of your existing switches) has control of the config. When you add new switches, you simply start configuring the new interfaces. The format will be <new-sw-#>/0/<port>
You can verify stacking with:
