Cisco FMC De-registration License

[chanthornloeurt]

Dear all,

Recently I've faced an issue related to my License status Cisco Smart Software Manager on FMC red marked (image attached) and I want to de-register and register my license back there is any effect on Anyconnect VPN or not?

The red icon for CSSM status is something we see regularly, mostly due to Cisco cloud issues. As long as your FMC shows authorized and the software.cisco.com portal isn't reporting any alerts, I recommend leaving the registration alone.

If you de-register and don't have licenses available, you will be prevented from deploying any changes that require the licenses. I'm not positive about AnyConnect during that period - I've never tried it. I have had expired AnyConnect smart licenses and could still login.

I do know that with the old style of AnyConnect PAKs, you are prevented from logging in if there are no available licenses.

Personally I consider that advice the Cisco equivalent to "turn it off and back on again". 

I have seen dozens of customer across multiple products encounter issues with registration to the Smart Licensing online backend services. 90% (or more) of the time it has nothing to do with the customer equipment settings, but rather issues that Cisco consistently refuses to acknowledge with their services.
