## POLICY BANKS

# %interface_policy = ();  # maps input interface/port to policy bank name
  
# $policy_bank{} = { ...predefined... };
    ## the built-in policy bank (empty name) is predefined, and includes
    ## references to most other variables listed above (the dynamic config
    ## variables), which are accessed only indirectly through the currently
    ## installed policy bank. Overlaying a policy bank with another policy
    ## bank may bring-in references to entirely different variables,
    ## possibly unnamed. Here is a list of configuration variables
    ## referenced from the built-in policy bank by keys of the same name
