this is not a huge issue, just an odd question. I'm sitting next to someone who's just getting their hands dirty with Cisco gear. So he asks me "when I do a 'show ?' cdp and interfaces isn't on the list". So I log in to see for myself (I never actually looked for cdp or int when doing a sho ? before), and sure enough it wasnt (but the command executes anyhow). when I enable on that same switch and do a 'sho ?' cdp and interfaces IS on the list.
I then logged into switches running other code, same thing on 12.2(25) and 12.2(53) both 3750g's. Also tried this on various 6500's, same result. 2800 router, same result.
Is there a good reason why those commands are ommitted from the list, yet still work from user exec prompt?
