vWLC: Re-registering with Smart Licensing

[stinkpad11]

Hi.

We've been hit with the following bug:

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvc62540

We're going to de-register and re-register the smart licensing, however we have 137 APs in production right now, with the evaluation license expiring a long time ago - what will happen to the APs in production while we're de/re-registering the smart license?

The evaluation timer will reset on reload if you need it to be applied. I'm not 100% on WLCs but all other wireless products like ISE/CPI will give you a warning when licenses are out of compliance but won't disable features until a grace period is over. I cannot say for certain but as adding/removing licenses doesn't disconnect APs I would not expect anything to happen when you de-register.

Depending what version of software you are running (I think it is 8.2 or higher) then you can also apply a RTU license for 150 APs and accept the EULA just in case this might affect your APs.. as the TAC case says RTU is recommended for permanent stability and I generally use those too for products that are trust based rather than hard coded like ISE/CPI.
