1). Cisco CCNA / CCNP Home Lab Setup: How To Configure Reverse Telnet By : Chris Bryant, CCIE #12933
Occasionally, during your CCNA and CCNP studies, you'll run into a term that just doesn't quite make sense to you. (Okay, more than occasionally!) One such term is "reverse telnet". As a Cisco certification candidate, you know that telnet is simply a protocol that allows you to remotely connect to a networking device such as a router or switch. But.

3). Cisco CCNA / CCNP Tutorial: Home Lab Assembly Case Study By : Chris Bryant, CCIE #12933
Part of your CCNA / CCNP education is deciding what network topology to use when you're putting together your home lab. Some of you are starting with one or two routers or switches, while others are starting with more. A customer recently sent me a list of his Cisco routers and switches that he has available for a home lab and asked for my help in coming up with the best way to use them.

5). Cisco CCNA Certification: Defining Broadcast Domains By : Chris Bryant, CCIE #12933
When you're studying to pass the CCNA exam and earn your certification, you're introduced to a great many terms that are either totally new to you or seem familiar, but you're not quite sure what they are. The term "broadcast domain" falls into the latter category for many CCNA candidates. A broadcast domain is simply the group of end hosts that will receive a broadcast sent out by a given host.

6). Cisco CCNP Certification / BCMSN Exam Tutorial: The HSRP MAC Address By : Chris Bryant, CCIE #12933
To pass the BCMSN exam and earn your CCNP, you've got to know HSRP inside and out! Part of that is knowing how the MAC address of the virtual router is derived, and another part is knowing how to change this address. We'll look at both features in this tutorial. We've got two routers on a segment running HSRP, so first we need to find out what the MAC address of the HSRP virtual router is.

7). Cisco CCNA Certification: How And Why Switches Trunk By : Chris Bryant, CCIE #12933
Your CCNA studies are going to include quite a bit of information about switches, and for good reason. if you don't understand basic switching theory, you can't configure and troubleshoot Cisco switches, either on the CCNA exam or in the real world. That goes double for trunking! Trunking is simply enabling two or more switches to communicate and send frames to each other for transmission to remote hosts.

8). Cisco CCNA / CCNP Home Labs: Developing Troubleshooting Skills By : Chris Bryant, CCIE #12933
CCNA / CCNP candidates are going to be drilled by Cisco when it comes to troubleshooting questions. You're going to have to be able to analyze configurations to see what the problem is (and if there is a problem in the first place), determine the meaning of different debug outputs, and show the ability not just to configure a router or switch, but troubleshoot one.

11). Cisco CCNP Certification / BSCI Exam Tutorial: Comparing IRDP And HSRP By : Chris Bryant, CCIE #12933
To pass the BSCI exam, you need to know the difference between IRDP and HSRP. While they have the same basic function, the operation and configuration of each are totally different. The aim of both is to allow hosts to quickly discover a standby router when the primary router fails. IRDP is commonly used by Windows DHCP clients and several Unix variations, but you do see it in Cisco routers as well.

Imagine this. You have an appointment with a client to work on a server or router install. A few minutes before you're scheduled to be there, you decide there's something really good on TV you'd like to watch. Or you decide to go to the gym, or play a game, or do anything else except go see the client. Even if you weren't going to get fired for not showing up, it's certainly unfair to the client.

17). Tips On Buying A Cisco CCNA / CCNP Home Lab Kit By : Chris Bryant, CCIE #12933
Buying a CCNA / CCNP home lab is the best way to be totally prepared for your Cisco exams. Most home labs are put together one router or switch at a time, but many CCNA / CCNP candidates prefer to buy kits where you get multiple routers and switches, along with all the cables and other connection devices you'll need. While this is a good idea, keep a few things in mind when purchasing Cisco home lab kits.

18). Make it Start with a Door Switch � Dishwasher Repair By : Tyler Anderson
You wouldn't even know your dishwasher had one until it isn�t working. These little switches are tucked inside the control panel of your dishwasher and most times are a part of the door latch. The door latch pulls the door securely to the main body of your dishwasher and prevents water from leaking during a cycle. If your dishwasher doesn't start, it could be due to a faulty door switch.

23). Cisco CCNA Exam Tutorial And Case Study: VLANs and IP Connectivity By : Chris Bryant, CCIE #12933
In this CCNA case study, we'll take some basic switching and trunking theory and put it into action. We have two routers (R2 and R3) along with two switches (SW1 and SW2). R2 is connected to SW1 at fast 0/2, and R3 is connected to SW2 at fast 0/3. Both routers have IP addresses on the 172.12.23.0 /24 network. For these routers to be able to ping each other, the switches must be able to communicate.

24). Cisco CCNA Certification: Cisco Switching Modes Tutorial By : Chris Bryant, CCIE #12933
To pass the CCNA exam and earn that coveted certification, you've got to know Cisco switches inside and out. Among the many important details you've got to know are the three methods that Cisco switches use to forward frames, and the differences between the three. The first switching method is Store-and-Forward. The name is the recipe, because that's just what the switch does - it stores the entire frame before beginning to forward it.
