How to Upgrade/Activate a License on a Cisco ASA (Adaptive Security Appliance)
About this video
This is a short, hands-on tutorial on upgrading a Cisco ASA license. Chuck says he will enable a Security Plus license on his ASA specifically to enable dual ISPs. He starts at Cisco’s product license registration site, enters the license key received from his vendor or Cisco reseller, and notes Cisco ties the license to the serial number of the device, so the key must be used on that correct ASA, and the license file is then sent by email. On the ASA itself, he enters global configuration mode, uses the activation-key command to paste in the key from the email, agrees to update flash, and saves with copy running-config startup-config. Before reloading, show version shows failover disabled, confirming Security Plus is not yet active. After the reload, he runs show version again: failover is now enabled with active/standby, and he points out his VLAN count has gone from three to 20. He closes by inviting questions and video ideas in the comments.
Key takeaways
- A Security Plus license on the Cisco ASA is presented here as the upgrade that enables failover and dual ISP connections
- Cisco registers the license against the ASA’s serial number, so the activation key only belongs on that specific device
- Install flow: register at Cisco, receive the key by email, then on the ASA use activation-key in global configuration mode
- Save with copy running-config startup-config and reload the ASA for the new license to become active
- Verify with show version: failover changes from disabled to enabled (active/standby) and VLANs rise from 3 to 20 in his example
