"Show Diag" command on 3750 IOS 12.1(19)EA1c

Question

Hi,
I'm trying to run the "show diag" command on a 3750 with IOS 12.1(19)EA1c and the command is not recongised. I'm in enable mode and cannot find an equivalent command.
I need to do this as the Cisco Software Advisor is asking for a copy of the output.
Any pointers gladly recived.
Cheers,

Hi,
The tool you need is the "Feature Navigator" which can be found here:
http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp
Launch the tool by selecting "Search by Feature"
Searching for "802.1x" gives a list of all those features, select "Wake on LAN support" (for example) and click add, then continue.
The platform box gives a list of all platforms that support the feature, so select 3750.
The lowest feature set is IP Base (you might have something else but worth checking this first as it's the lowest feature set)
This gives a list of about 20 versions of software which support the feature so you can see you need at least 12.2(25)SEC to get this particular feature.
The process is pretty much the same for any feature. If you know the actual command you need (in this case it's "dot1x control-direction" then you could get the same info by just looking it up in the latest command reference as that will also tell you when the feature first appeared.
Finally, if you just want a list of features for a particular release then use the same link and choose search by platform, but be aware this will be a *long* list.
