The code running in the ASICs on line cards in 6500-series
chassis isn't fixed at the factory. Same with the code running on the
PFCs in those boxes. There's not a tremendous amount of flexibility to
make changes after the fact, because the code is so tightly integrated
with the hardware, but there is some.
(Not saying the 6500 is a software-based platform. It's pretty clearly
a hardware-based platform under most peoples' definition. But: the
line is blurry.)
