Which IOS version implemented the do show command?

I always thought it was 12.2 but using packet tracer with a 2950 switch with 12.1, there was that do show command.

I could be wrong, if I remember right the command was first introduced in release 12.1(11b)E

When in doubt, check the command reference doc(s) -- if you can find them since the Cisco Doc changes

Cisco IOS Configuration Fundamentals Command Reference - D through E [Support] - Cisco Systems

12.2 ( 8 ) This command was introduced.

Now the switch IOS versions.... that might take some research unless you limit it to a specific switch family/model.

Packet Tracer = Simulator. It doesn't run IOS at all and just gives you a UI that contains a subset of IOS commands/features for that particular platform. I wouldn't make any conclusions about real hardware just based on what Packet Tracer does or doesn't do.

I wish I was the first to answer this haha. It would have made me look so smart

. I remember the CBT Nugget when Jeremy said it.

This may be kind of unrelated but definitely make sure you know the full versions of the regular commands you use for the test (that's all I can say without violating NDA) lol.
