Cisco CCNP Certification / BCMSN Exam Tutorial: Writing QoS Policy
QoS - Quality of Service - is a huge topic on both the BCMSN exam and real-world networks. QoS is so big today that Cisco's created separate specialist certifications that cover nothing but QoS! It can be an overwhelming topic at first, but master the fundamentals and you're on your way to exam and job success.
If you work with QoS at any level - and sooner or later, you will - you've got to know how to write and apply QoS policies.

Cisco CCNP / BCSI Exam Tutorial: Configuring EIGRP Packet Authentication
Configuring RIPv2 and EIGRP authentication with key chains can be tricky at first, and the syntax isn't exactly easy to remember. But for BSCI and CCNP exam success, we've got to be able to perform this task.
In a previous tutorial, we saw how to configure RIPv2 packet authentication, with both clear-text and MD5 authentication schemes. EIGRP authentication is much the same, and has the text and MD5 authentication options as well.

Cisco CCNP / BSCI Certification: Introduction To ISIS Terminology
When you're studying to pass the BSCI exam and earn your CCNP certification, you're going to be introduced to ISIS. ISIS and OSPF are both link-state protocols, but ISIS works quite differently from OSPF. You must master these details in order to earn your CCNP.
One of the major differences between OSPF and ISIS will be evident to you when you first begin your BSCI exam studies, and that is the terminology.

Cisco CCNA / CCNP Home Lab: Why You Need An ISDN Simulator
ISDN is a vital topic for today's CCNA and CCNP candidates, especially for the ICND and Intro exams - you've got to know ISDN inside and out to pass those exams. Naturally you want to include it in your home lab. What many candidates don't realize is that you can't connect two Cisco routers directly via their Basic Rate Interface (BRI) interfaces you've got to have another device between them called an ISDN simulator.

Be Certifiable! The Basics Of MCSE And MCP
It is not always who you know, but what you know. That is why obtaining Microsoft certification can be a valuable asset to your career. Of course, it does depend on what career path you want to take as to whether you want to get either MCSE training or MCP training or anything else for that matter. So what do those abbreviations MCSE and MCP stand for anyway?
MCP stands for Microsoft Certified Professional and MCSE is an abbreviation for Microsoft Certified Systems Engineer.

Cisco CCNP / BCSI Exam Tutorial: Broadcasts And The IP Helper-Address Command
While routers accept and generate broadcasts, they do not forward them. This can be quite a problem when a broadcast needs to get to a device such as a DHCP or TFTP server that's on one side of a router with other subnets on the other side.
If a PC attempts to locate a DNS server with a broadcast, the broadcast will be stopped by the router and will never get to the DNS server.

Cisco CCNA / CCNP Home Lab Tutorial: Using 2520 Routers
I know from experience that part of the excitement and anxiety of putting together your own CCNA / CCNP home lab is deciding what to buy! While you can make a workable home lab out of almost any combination of Cisco routers and switches, some routers are better suited for home lab work than others because they can fill multiple roles.
My personal favorite is the Cisco 2520.

CCNA / CCNP Home Lab Tutorial: The VLAN.DAT File
CCNA and CCNP candidates who have their own Cisco home labs often email me about an odd situation that occurs when they erase a switch's configuration. Their startup configuration is gone, as they expect, but the VLAN and VTP information is still there!
Sounds strange, doesn't it? Let's look at an example. On SW1, we run show vlan brief and see in.

Cisco CCNP / BCMSN Exam Tutorial: Changing Root Bridge Election Results
Your BCMSN and CCNP studies will include mastering the details of Spanning Tree Protocol (STP). While you learned some of these details in your CCNA studies, quite a bit of it may be new to you. Before going on to the intermediate and advanced STP features, let's review the root bridge election process and learn how to change these results.
Each switch will have a Bridge ID Priority value, more commonly referred to as a BID.

CCNP Certification / BCMSN Exam Tutorial: HSRP MAC Addresses And Timers
To earn your CCNP certification and pass the BCMSN exam, you've got to know what HSRP does and the many configurable options. While the operation of HSRP is quite simple (and covered in a previous tutorial), you also need to know how HSRP arrives at the MAC address for the virtual router - as well as how to configure a new MAC for this virtual router.

Cisco CCNP / BCMSN Exam Tutorial: Switches, QoS, And Cisco's Networking Model
QoS is a big topic on your BCMSN and CCNP exams, and for good reason. As more and more traffic flows through today's networks, accurately applying QoS to both your routers and switches becomes more important.
Note the phrase "accurately applying". You must have a plan in place before you start configuring QoS on your switches, and to create such a plan you should use Cisco's Three-layer Hierarchical Model.

Cisco CCNA Exam Tutorial: Troubleshooting Directly Connected Serial Interfaces
CCNA exam success depends largely on noticing the details, and this is especially true of configurations involving directly connected serial interfaces. And of course, it's not enough to notice these details - you've got to know what to do about them!
A Cisco router is a DTE by default, but directly connecting two DTEs with a DCE/DTE cable is not enough.

Cisco CCNA Exam Tutorial: Using Trivial File Transfer Protocol (TFTP)
One of the first things you do when you start studying for the CCNA exam is memorizing a list of port numbers and the protocols that run on those ports. If you're an experienced networker, you know most of the protocols that are mentioned - DNS, DHCP, FTP, SMTP, and so on. But there's one protocol that you might not have experience with, but is actually vital for CCNA exam success and success in working with Cisco routers and switches, and that's TFTP - Trivial File Transfer Protocol.

Passing The CCNA and CCNP: Three Myths About Cisco Exams
One of the drawbacks to the Internet is that it allows myths and "friend of a friend" stories to spread quickly, and usually the story becomes more exaggerated as it's passed along. Cisco exams are no exception. Here are three often-repeated myths and exaggerations regarding the CCNA and CCNP exams.
1. The survey you fill out before the exam determines the questions you'll get.

Cisco CCNP / BSCI Exam Tutorial: OSPF Route Redistribution Review
OSPF route redistribution is an important topic on the BSCI exam, and it's a topic full of details and defaults that you need to know for the exam room and the job. To help you pass the BSCI exam, here's a quick review of some of the OSPF route redistribution basics.
To see if a router is an ABR or ASBR, run show ip ospf. This also displays any routes being redistributed into OSPF on this router.

Cisco CCNP Certification / BSCI Exam Tutorial: ISIS Hellos And Adjacencies
In my last ISIS tutorial, I mentioned that while ISIS and OSPF are both link state protocols, their actual operation differs greatly. To pass the BSCI exam and earn your CCNP, you'll need to know these differences! Today, we'll take a look at ISIS Hello types and the adjacency types that form through the use of these Hellos.
Hello packets have been mentioned several times with ISIS, and with good reason.

Cisco CCNA Certification Exam Tutorial: Access List Details You Must Know!
To pass the CCNA exam, you have to be able to write and troubleshoot access lists. As you climb the ladder toward the CCNP and CCIE, you'll see more and more uses for ACLs. Therefore, you had better know the basics!
The use of "host" and "any" confuses some newcomers to ACLs, so let's take a look at that first.
It is acceptable to configure a wildcard mask of all ones or all zeroes.

Cisco CCNA Certification Exam Tutorial: The OSPF RID
OSPF is a major topic on your CCNA exam, as well it should be. OSPF is a widely-used WAN protocol, and you need to learn the fundamentals before moving on to more complicated configurations. One such detail is the OSPF Router ID, or RID.
The RID is the dotted decimal value by which other OSPF routers will identify a given OSPF router. There are some interesting defaults for this value, and a command you should know to hardcode the RID.
