To define the maximum number of interfaces that the IPSec tunnel profile can instantiate, use the max-interfaces command. Once the profile reaches the maximum number of interfaces, the profile rejects any new interface instantiations and generates a warning-level log. The default value (using the no version of the command) specifies unlimited interface instantiation on a given profile.
