Where's my "do" command?!

Well I was playing around with a router today and I went to use the greatest command ever (do) and I got invalid input detected... First time I have ever gotten that while trying to use the do command. I assume it is because of the IOS (c2600-i-mz.121-2) that is on this particular router. This is also the first time I have used an IOS other than the more feature packed IOSes like advipservicesk9-mz.123-11.
That made me curious what IOSes do not support the do command? And who else is driven nuts by the fact that you can not use the do command on the test sims?
Edit: Forgot to mention, if I do #do ? I get "<0-999999>.<0-999999> Version number
"
What's that about?

I'd have to agree with you I think I had the same issue on an older version of IOS.. -

scheistermeister,
According to the Command History section of the "do" command in the "Cisco IOS Configuration Fundamentals Command Reference" it states "Release 12.2( 8 )T - This command was introduced."

I didn't learn about it and the | until I watched CBT Nuggets for the forst time when I started the BSCI in the Net Acad. Two of the best commands I have ever learned.Give a man fire and he'll be warm for a day. Set a man on fire and he'll be warm for the rest of his life. -

What does "do" refer to? I know what the command does but why did they choose the word "do"?Next up:

"do this enable command in global config mode"
It makes it so that you can execute commands without exiting global config and following config modes first.CCNP | CCIP | CCDP | CCNA, CCDA

for example
'do show running-configuration' works from an interface config mode.
Its great for running show commands without having to come all the way out of the middle of a config. -

So why not just enable the same command in global config mode? Couldn't they just allow "sh run" in global config?Next up:

Probably, but the code change required would have been prohibitive since they would have had to account for all 12 bazillion commands.tomset wrote:Paul Boz wrote:tomset wrote:What does "do" refer to? I know what the command does but why did they choose the word "do"?
