Scope
Valid scopes are listed in the following table.
Type
Valid types are listed in the following table.
Scope Description
REQUIRED Variables defined as REQUIRED in scope can be used in multiple sections, but only
once within the Declaration section.
No values can be defined for a REQUIRED scope variable. Its value must come from
the GetWanPolicy request.
OPTIONAL Variables defined as OPTIONAL in scope can be used in multiple sections of a policy,
but only once within the Declaration section.
OPTIONAL scope variables are assigned to a default value. These values are not
initialized. They are set only if a value is not passed. If a WAN policy request does not
pass a new value to the parameter that matches in both name and type, the value
defined in the Declaration is used when processing the policy.
You must assign a value to variables defined as OPTIONAL in scope. Therefore,
because TIME and NETADDRESS types cannot be initialized in the Declaration
section, do not use an OPTIONAL scope with these variable types.
LOCAL Variables defined as LOCAL in scope can be used in multiple sections, but only once
within the Declaration section.
LOCAL scope variables exist only for a particular policy; that is, their values are not
returned to the calling client.
All parameter types can be defined. However, because TIME and NETADDRESS
types cannot be initialized in the Declaration section, do not assign values to these
types.
SYSTEM Variables defined as SYSTEM in scope can be used in multiple sections, but only
once within the Declaration section.
Type Description
INT Reflects the traffic type of the GetWanPolicy request that the policy is being run for.
For example, the following policy specifies a Traffic Type of NDS_SYNC:
IF TrafficType=NDS_SYNC THEN action END.
BOOLEAN Used for values of only TRUE or FALSE. The value will be indeterminate if it is not set
in a Declaration or a WAN policy request.
TIME TIME scope variables must receive their values in the Selector or Provider sections or
from the WAN policy request. Do not assign values to TIME scope variables in the
Declaration.
NETADDRE
SS NETADDRESS scope variables must receive their values in the Selector or Provider
sections. Do not assign values to NETADDRESS scope variables in the Declaration.
