I did see this document and the chart listed. However another document says:
Limitations and Restrictions
This section describes the limitations and restrictions for the Catalyst 6000 family NAM software release 2.1(2):
You must run Catalyst software release 6.1(1d) or later on your Catalyst 6000 family switch. Optionally, you can enable mini-RMON on the switch to monitor switch port data and set switch threshold alarms.
The above only applies to CatOS and not to NativeIOS. If your switch is running CatOS, then the above is true. If your switch is running NativeIOS then what I listed earlier is true. CatOS and NativeIOS are not the same.
