CCNA Security Commands

#01 solara

As part of my study for CCNA Security I have been making a list of all the commands I need to be adept with. I thought I would share this list of commands with others who may be interested.

For simplicty the list doesn’t offer explanations and in most cases there are a variety of options that could be used with each command that are not shown. It is also not suitable for copy/paste into a router or switch. However, I think it is still a useful quick reference sheet.

You are running both RADIUS as well as TACACS+ servers in your example configuration. I was wondering what RAD/TACS you were running on those two servers? FreeRadius? And what Tac Plus? Just trying to determine what software you are using for your lab studies! Thanks!

By the way, thanks for sharing your config!

The previous example isn’t my config but rather just a list of commands to be familiar with and so I’m not actually running TACACS+ and RADIUS on the separate server addresses that I have shown.

I do my lab work using GNS3 with the C3745-ADVENTERPRISEK9_SNA-M IOS and currently I’m using the 90-day trial version of Cisco ACS 4.2 running on a Win2k3 VMWare box.

Just for interest I’ve attached a text file showing a basic config I’ve used for testing TACACS+. I have enabled debugs on aaa authentication and IP packets between the router and the ACS server and then attempted to logon to the router via SSH.
