This defines the minimum classification level which
is acceptable by this port. This applies to any packet
which is entering or leaving this port. If the
classification level is outside the range defined by
the value of this object and the value of a3IPsecureMaxLevel,
the packet is discarded.
If a3IPsecureMaxLevel is set to level less than the level
indicated by this object, the value of this object will
be shifted so it is equal to a3IPsecureMaxLevel. This
will ensure that the range of security levels identified
by these two objects makes sense.
