ASA temporary license

August 25th, 2008 • Related • Filed Under

You may or may not be aware but the ASA does allow for temporary licenses for certain feature sets in order for you to test these features for an extended period of time (like 30 days). However I’ve received quite a few emails regarding what happens to the ASA after the temporary license for a feature (say SSL VPN) expires. Questions like, how do I go back to the original license that the device came with? or do we have to restart the ASA?

Well here’s what happens, when a time based license expires, the ASA will switch back to the installed permanent license automatically. If no permanent license is available, then the ASA defaults for no license will be set. The device should not require a reboot, unless a feature, like failover, requires a reboot for deactivation. For example. if failover is enabled in the temporary license but not in the permanent license then a reboot will be required. Also all VPN features should not require a reboot….
