we are getting a 6509 with sup.720. I am just wonderig if we should load CatOS on it or go with IOS. The switch is going to be housing some 20 vlans (IP only) and not do much of anything else (no BGP, OSPF, IPX or anything) besides acting as a big L3 switch. I've worked on an old cat4006 running catos5.5 and I found it kind of limited with regards to access-list functionality. anyone? Thanks,
