Hi,
Well depending on your "black box", your millage will vary.
Their wide use of ASIC eliminate a lot of the headache of pure
software implementation.
Buffer, timing, expected results, etc.
Their "real" sofware only represent a small part of the device and
is mostly relegated to management and some L4 to L7 handling.
So yes, ASIC/FPGA devices have "software" their result and behavior
are predictable and the system is more stable because of it.
PS: Yes, CAM lockout, bad RAM is still a pita for them.
In short:
It is quite a thing to say that because everything can be
categorized as "software" that someone point is invalid.
