vWLC 9800 N+1 automate configuration replication in an n+1 environment

[Guillermo_PY]

Hello Team,

I would to know if someone knows how to automate the config replication between two vWLC9800 operating in N+1.

Do any idea or third party software?

What I do in N+1 is backup the good controller configuration and edit that for the other N device.  You don't want to just replicate everything in case something was configured and broke something.  You want to make that change manually or script something that works for you.

I use a software called Meld to diff between the files.  This way I know what command lines are different, what might be missing in one or needs to be removed in the other.

i have not come across any tool, other than compare or do manually both same config.

basically after setup both WLC we do not make any major changes, other than adding new SSID or any Major config, we do manually i guess here.

Hi @Scott Fella thanks for your response. The idea is to have a script or something to be easier for the administrator.

If you are handing this off to a customer, I think a script might be a bit overwhelming especially if they make changes or have to make changes to the primary N device in the future.  If you manage this network, then I think it's fine because you would understand the script and would be able to update the script in the future.  Code upgrades can change the commands used and can enable/disable settings, so be careful.  If you really wanted no touch, SSO would of been better, but that is a whole other story.
