• IP Security
• IP Stack
• L2TP Tunneling
• Radius Client

The features are activated by the presence of a specific key file in flash memory.
When the appropriate key is present, the feature is enabled and access to the feature
is allowed through the command line or Web Management interface (based on user
privileges).
Adding and Deleting Feature Keys
A software option key is a 76-character string, unique to a particular router. There are
four key types:
• Activation Key - used to enable or extend the life of a specified feature. This
key is purchased and entered manually.
• Revocation Key - indicates a feature key has been revoked. This key is
internally created when the command to revoke a feature is issued. the
feature will display a key but the feature will not be enabled.
• Unrevoke Key - used to nullify a revocation key and re-enable the feature
activation key. This key is also purchased and entered manually.
• Manufacturing Key - indicates a feature key that was installed during the
manufacturing process.
