Hello all,
I am looking to upgrade the IOS on my 6509. It has redundent sup 720's with a MSFC3A. 64MB Flash and 512 RAM.
Currently it is running 12.2(17D)SXB2. Anyone have a recommendation or running a higher version of IOS that is stable?

We use 12.2(18)SXD7.
Safe harbor release are:
12.2(17d)SXB1012.2(18) SXE4
12.2(18)SXFAre you looking to upgrade to get a particular feature ?
We will be adding 10GB blade in the near future. Otherwise it is just to keep the code current.
I did a lot of work in the area of 6500 for a major finacial institution and determining the "best" image to upgrade was absoutely vital.
There are still quite a few bugs in many of the 6500 releases, so my advise would be not to upgrade unless you REALLY must.
If you need to upgrade, ensure you go thru all the caveats listed for the target IOS release to determine if they might be triggered in your environment.
If you have WS-X67xx cards make sure you have at least 12.2(18)SXE4, though the particular bug bit us seems to have cropped up again in the last few days. The effect of the bug was to drop traffic from the board to external addresses (for some value of "external") but allow local traffic to flow uninterrupted.
