Change config on one switch and have it apply to every switch on the network

[lpescato]

Hi Everyone,

I was wondering:

Say you wanted to add a user to your config, but you have 30 switches in your lab and only want to configure one, but have the config propogate to all the switches.

Is this possible, and if so, what is the CLI for it?

Thanks

Larry

Hi Larry,

I'm not an expert in this area but here's what I have:

Switch Stacks

• One option (if lab area allows) is physically "stacking" your switches (requires a special cable).
• The limitations are:
  • You can only have so many in a stack (12 max I believe)
  • They will need to be stacked (and therefore, that restricts your distance to devices)
  • If this option works for you, updating one switch updates them all because they act as one logical device.
  • More on that here

SmartInstall

• However, what I believe you might be looking for is SmartInstall.
  • This is used for zero-touch switch deployment.
  • While there are other (non-Cisco solutions), this is the one I've heard of before.

Hope that helps,

Dan

If this is a lab environment and a one-off, then a script would work (Python).  Ping me and I can possibly help create something (ktbyers at speakeasy dot net).
