Recently bought a used 6509 with a Sup-720, it came with a compact flash and seems like the version on it is:
12.2(18)SXF8 (advanced enterprise services)
Now on cisco's website, it shows like a SAFE HARBOR but when clicking on safe harbor but when going on this link:
it shows under "IOS Software Modularity" that the version we have is NOT RECOMMENDED. Can anyone comment on this please?
