There are situations where your Cisco hardware fails and you will need to replacement
most of the times hardware is sent with the correct licensing and often times you are actually missing the key features like Failover and VPN
below is an example of a device with the failover license disabled
If you ever run into that you will need to call Cisco support again and get an activation key for your Cisco ASA firewall/VPN
The process is fairly simple and all you need is to copy the key that is sent to you and use the below command to activate the feature – the command is called “activation-key” and then the code that is sent to you by Cisco Support
Once you hit enter – please confirm and this will apply the activation key
Once the activation key is applied then you will need to reload the ASA to get the activation key to take effect
