There is indeed no ISSU on 6500. What you are referencing is FSU or eFSU.
I would suggest you get a product brief from your Cisco team or your
preferred vendor/reseller.
i
recently upgraded from sxi2a to sxi6 with no noticeable impact if you
do it right.
ISSU has the ability to have 0 impact.
that said, you do lose 50% of your cluster capacity. so i
guess it depends on your interpretation/requirement for ISSU ;-)
This isn't an interpretation, unless it's yours. The rest of the world
that is familiar with the 6500 will tell you the same. That's FSU or a
variant.
on the flip, i can attest that sometimes ISSU doesn't work for various

If you are referring to the 6500, it doesn't work because it doesn't exist.
