I just got a new registration key from Cisco by using my Serial Number (we had some problems with the memory getting erased) I was just wondering if anyone knew the exact command to load the new key onto my ASA 5520??
Chris, here's a cut and paste from the site:
Entering a New Activation Key
To enter the activation key, enter the following command:
hostname(config)# activation-key key
The key is a four or five-element hexadecimal string with one space between each element. For example, a key in the correct form might look like the following key:
0xe02888da 0x4ba7bed6 0xf1c123ae 0xffd8624e
The leading 0x specifier is optional; all values are assumed to be hexadecimal.
If you are already in multiple context mode, enter this command in the system execution space.
Before entering the activation key, ensure that the image in Flash memory and the running image are the same. You can do this by rebooting the security appliance before entering the new activation key.
