Cisco Certified Network Associate (CCNA®) validates the ability to install, configure, operate, and troubleshoot medium-size route and switched networks, including implementation and verification of connections to remote sites in a WAN. CCNA curriculum includes basic mitigation of security threats, introduction to wireless networking concepts and terminology, and performance-based skills. This new curriculum also includes (but is not limited to) the use of these protocols: IP, Enhanced Interior Gateway Routing Protocol (EIGRP), Serial Line Interface Protocol Frame Relay, Routing Information Protocol Version 2 (RIPv2),VLANs, Ethernet, access control lists (ACLs).
A Great First Step into VoIP
Jul 21st
If you are like me, you want to take your knowledge of all the major Cisco Certification areas to at least the Professional level. For those intimidated by the VoIP track, have I got great news. One of the greatest Cisco Press titles ever written (in my biased and humble opinion) is the Voice over IP First-Stepby my good friend and colleague Kevin Wallace.
While I was re-reading this book recently, I decided I would provide students with my list of Active Reading questions I developed. I would recommend you feed these into your SuperMemo app, or use one of the many Flash Card makers on the Internet if you are interested in mastering this exciting track.
Here are my queries from Chapter 1 Touring the History Museum of Telephony. For many blog readers, you might want to just challenge yourself with how many of these you can get without research. Enjoy! More >

CCNA 640-801 Exam Notes – Fundamentals of Switching
Jun 11th
Fundamentals of Switching
1. LAN Segmentation
1.1 In a collision domain, a frame sent by a device can cause collision with a frame sent by
another device in the same collision domain. Moreover, a device can hear the frames
destined for any device in the same collision domain.
1.2 In a broadcast domain, a broadcast frame sent by a device can be received by all other
devices in the same broadcast domain.
1.3 A LAN segment or an Ethernet network segment consists of the devices connected with
a coaxial cable or a hub. The devices are in the same collision domain.
1.4 Ethernet congestion problem occurs when too many devices are connected to the same
Ethernet network segment, such that the high network bandwidth utilization increases the
possibility of collision, which causes degradation of network performance. More >

Welcome to the exciting world of internetworking. This first chapter will really help you understand the basics of internetworking by focusing on how to connect networks together using Cisco routers and switches. First, you need to know exactly what an internetwork is, right? You create an internetwork when you take two or more LANs or WANs and connect them via a router, and configure a logical network addressing scheme with a protocol like IP.
I’ll be covering these four topics in this chapter:
- Internetworking basics
- Network segmentation
- How bridges, switches, and routers are used to physically segment a network

CCNA LAB:Configuring an IP Address(8)
Jun 9th
Configuring an IP Address
As we continue with the manual reconfiguration of our router, we will now configure two interfaces: Ethernet0 and Serial0. To configure IP routing and then configure Ethernet0 and Serial0 interfaces with IP addresses we enter the following:
Router(config)# ip routing Router(config)# int e0 Router(config-if)# ip add 192.168.1.1 255.255.255.0 Router(config-if)# no shutdown Router(config-if)# int s0 Router(config-if)# ip add 192.168.2.1 255.255.255.0 Router(config-if)# no shutdown Router(config-if)#
You can see that we entered commands for the Ethernet0 and Serial0 interfaces without having to exit back to the global config mode between interface commands.
Notice that we are in the global config mode when we turn on IP routing. However, turning on IP routing is not necessary on any Cisco router, because IP routing is enabled by default.
We enter the interface “subcommand” mode with int e0 (interface Ethernet0). We must specify the subnet mask when entering an IP address. Notice that we are using the full sense of the 24-bit mask with three 255s, where each 255 represents 8 bits. Remember we entered a zero when we ran the Setup script, because the Setup script uses zero to represent subnet mask defaults, and in this case, the default subnet mask for this Class C network is 24 bits.

CCNA LAB:Setting Router Passwords(7)
Jun 9th
Security is important on a router. Remember that you can access a router from connections other than the console. There are five separate passwords you can set to protect your router:
Console: protects the Console Port
Enable Password: guards the use of the Enable mode super-user status
Enable Secret: an encrypted secret form of the above (better!)
VTY: protects against unauthorized Telnet port logons
Auxiliary: protects the AUX Port (for your modem)
The Console Password
As we continue with our manual reconfiguration tasks, your very next step should be to set the password for the Console Port. Starting from the Router(config)# prompt you need to put in the following series of commands to create the password. More >

CCNA LAB:Manual Router Configuration(6)
Jun 9th
Right after running the Setup script, or whenever you need to change your router’s configuration, the best way to get the most out of a Cisco router configuration is to do it manually via the CLI and config mode.
Let’s pretend that we didn’t go through the Setup script as shown in the last section. Through our terminal emulation program, we will see the router boot up just like before. When we get the prompt asking if we’d like to enter the initial configuration dialog, we can simply type “n” as shown below and then press the Enter Key. The router will ask us if we want to terminate autoinstall. Our answer to this will be “yes.” If we were to say “no,” the router would spend a lot of time looking for configuration files from network servers. (We’ll discuss this more in a later section.) As shown in the Setup script instructions, another way to get out of the Setup script is to just press [Ctrl-c] at any point in the script. More >
