Re: 6500 Supervisor IOS/Native mode (RE: 12000 ACL issue)

So, just curious if there's a large crowd going towards 6500
"native" mode (using Supervisor IOS instead of CatOS
"hybrid" dual-headed monster).




Probably not because of POS modules lack of support in Supervisor IOS.

People doing DFC and SLB are required to run Supervisor IOS; people that
doesn't like the vlan/port metaphor tend to run Sup IOS.




I've heard of a few enterprise- and metro-area networks
migrating from a 7500+GSR platform to 6500's, but none are
running 6500 native mode.

Seems like native mode is pretty new, maybe 18 months old
now. Not many IOS versions to choose from, but plenty of
bug-fix releases (5 since Aug '01). Curious whether anyone




The Sup-IOS releases are usually paired with CatOS or MSFC IOS upgrades,
correcting similar bugs and adding similar funcionality. Very few bugs were
SupIOS-related, as far as can I tell from the release notes (which doesn't
always include all that have changed).




is testing or operational with it, and what your experience
has been.




Most of the times we hit a CatOS bug we also tried the current SupIOS
release on lab, and the same bug was also present... it would probably make
no difference to run either of them, unless you use something exclusive to
SupIOS that would have its own bugs.
