Security: IPv6 First Hop Security : Policies, Global Parameters and System Defaults
 
Policies, Global Parameters and System Defaults
Each feature of FHS can be enabled or disabled individually. No feature is enabled by default.
Features must initially be enabled on specific VLANs. When you enable the feature, you can also define global configuration values for that feature’s rules of verification. If you do not define a policy that contain different values for these verification rules, the global values are used to apply the feature to packets.
