RE: IOS Features

Hello Aaron!

Sadly, there is no single location of cool features in the documentation.
You should plan on spending many hours exploring the 12.4 docs to
familiarize yourself with the many features possible.

Let me walk you through navigation for your first example so you get a sense
for how you could refresh yourself on those options during the actual CCIE
Lab Exam.

Cisco.com - Support - Configure - Products - Cisco IOS and NX-OS Software -
Cisco IOS - 12.4 Family - 12.4 Mainline - Configuration Guides - Cisco IOS
Security Configuration Guide: Securing User Services, Release 12.4 - Cisco
IOS Login Enhancements (Login Block)

You should also keep in mind that many cool features can be found as part of
the New Features area. Here is your navigation for that:

Cisco.com - Support - Configure - Products - Cisco IOS and NX-OS Software -
Cisco IOS - 12.4 Family - 12.4 Mainline - Release and General Information -
Release Notes - Cross-Platform Release Notes for Cisco IOS Release 12.4,
Part 3: New Feature Descriptions and Important Notes

Continue to enjoy your Cisco studies!

Subject: IOS Features

I was recently introduced to a few very cool/interesting features in IOS
(IOS's feature richness continues to amaze me).. Question please..is there a
certain area of the DocCD that I could go to find various features like
this.? I know where a lot of things are in the DocCD, ip rout prots, IP
services, etc, I just don't know where Features like this would be located.
If you could tell me like, click, products, Cisco ios and NX OS software,
Cisco IOS, 12.4 Family, Cisco IOS Release 12.4T, etc, etc..that would be
great.
