Configuring AAA – Locally

SecureA while back I talked about AAA but never put out a post on how configure it until now. In this post I am going to be going over the configuration steps of how to configure AAA locally on a Cisco router, (The same commands would also work on Cisco switch). To review what exactly AAA does check my earlier post Understanding AAA. Continue reading “Configuring AAA – Locally”

Introduction into Cisco Configuration Professional

Let’s walk through the basics with Cisco Configuration Professional as it is a helpful tool to use at the associate levels of the Cisco certification track and needed if you are looking at getting the CCNA Security certification. In this introduction we will introduce CCP and setup a community and then finally discover our devices within CCP. This is not the first GUI tool Cisco has produced to manage individual routers, an older tool called Cisco SDM also helped Network Administrators which supports the ISR Generation 1 routers. In this blog a while back I talked about Cisco SDM and walked through some tutorials on using it. Although it’s reaching age with Cisco support it is still officially supported until February 28th 2014. The good news with CCP is it supports these older ISR Generation 1 routers as well as the new ISR Generation 2 routers, were Cisco SDM only support ISR G1 routers.

Archive your Configuration

Hard-DriveIt is important to save your router and switch configuration but what happens if the device fails or if you saved a configuration mistake, without having to manually worry about it? Well if your Cisco router or switch has Cisco IOS 12.3T and higher you would be able to set up an auto archive within the flash memory of the unit or you can send that configuration file to a server that does either FTP, HTTP, SCP. TFTP, etc. Let’s work through on setting up the archive feature on a Cisco Router. Continue reading “Archive your Configuration”

Configure DHCP on a Cisco Router

In this short tutorial let’s configure a DHCP server on a Cisco Router. Why would we want to do that? Well configuring a basic DHCP server on a router is a good idea if this is a branch/satellite office or just a small business. There are some pros and cons of configuring DHCP on a Cisco Router so let’s briefly discuss them and then start configuring. Continue reading “Configure DHCP on a Cisco Router”

HDLC vs. PPP

HDLC and PPP are considered to be in layer 2 of the OSI model. There are some differences between which will be describe in this post, If you would like to learn more about at least the basic configuration of PPP including PAP and CHAP check out the post I wrote about year ago. (Basic PPP Configuration) HDLC was first developed by the ISO Cisco tweaked the protocol sometimes called cHDLC and because of this it only works with Cisco equipment. PPP is defined by RFC 1968 which is an open standard and is able to work on multi-vender equipment. Continue reading “HDLC vs. PPP”
