First of all you’ll need to unlock the toolbar. Just right-click on it and the Lock uncheck Toolbar. Now you can move the Favorites Bar and the Command Bar anywhere you like and how much space personnaliser chaque bar uses. You can also hide the Favorites Bar IE8 to make look like IE7, or hide the Command Bar, si vous n’avez pas besoin it (or both for that matter). If you like having the Menu Bar at hand, right-click on the toolbar and select Menu Bar It will appear.

There is a thing I really like about Internet Explorer 8 – where you can choose to have the Refresh and Stop buttons – to the left of the address bar, or to the right of it.

If you have any third-party toolbars installed, sometimes you might want to close them quickly. That’s really easy with IE8, because each toolbar will have a close button (X) from now on. To activate your toolbars installed right-click on the toolbar area and choose the third-party toolbar you want to appear.

And last but not least – d’utiliser Internet Explorer, add-ons, such as search tools, accelerators, and web slices. They can be really handy and web browsing can make a lot more enjoyable. You can get from various IE extensions http://ieaddons.com.

You need a router physical simulators simply not give you the “hands on” you need to see what happens if you use a cable, a cable in the wrong position or simply configure the interface incorrectly . Depending on what you make mistakes, you can use the interface or protocol and on the basis, it should give you an indication where the breakdown started (Note, the interface layer, and what is layer protocol). Anyway, you can find very quickly that the error on the router 1 router 4 all, because you do not live in a cable. No simulator allows the simulation that if a router is invaluable.

I have sometimes wondered if someone can D-Link “router” or in their laboratory. This class at home “router” in general, does not support protocols like RIP, OSPF, IGRP, etc, they still have the Cisco IOS, CCNA the majority of the audit. The answer is that they are not really for the development of your Cisco CCNA Lab.

Like many Cisco routers do I need?

Two routers really necessary to see if this works. If you have a limited budget, you can only purchase a router in cooperation with a simulator. However, you will not be able to see the most important, what we are trying to achieve. The multiplication of the Route of the routing tables and data! The only way you can see if your configuration to work is that at least two routers. In other words, if you can afford to make a package of more than two routers, you can exercise complex scenarios. I would recommend a router Dual-Kit or best, with all the accessories you need. Otherwise, you can use for days or weeks to find all the little extra pieces you need for your laboratory and exploitation. I recall, like other retailers, who with his games of 2500 and the routers are not transmitting. Now, as the Ethernet AUI ports without them? It is, in fact, as I read. A router gives you the opportunity to control and allow you to memorize the syntax and the context in which enforcement orders. Two routers, you can be, for a routing table to disseminate information, data and multiplying the path of choice. In addition, you will see basic device elections. With three or more, you receive all routers these elections and the complete device. I hope these tips help CCNA Lab Kit for your budget.

Can we, a laboratory, it is each concept CCNA Exam?

We often receive this question. Yes we can, but it is not realistic for most customers, who himself studied, because it cost over $ 5000 If you have this kind of budget available, we recommend you choose the CCNP kits, as for you by your CCNA exam and on your way towards your CCNP.

Like many Cisco routers and Cisco switches do I need for your CCNA Lab Workbook?

Our Lab CCNA workbook has been informed that most of our customers can not afford a large laboratory. Note that you will see a large number of laboratories for three of the four Router below. This does not mean you can not complete most of them. It is easy in most cases means that it is not as complex as it be.
Number of laboratories, a single router – 7

Number of laboratories, the two routers – 11

Number of laboratories, the three router – 19

Number of laboratories, the four-router – 4

Number of laboratories, one or more switches – 8

What are some things to check, I am for my CCNA Lab?

Two new themes emerged from the verification of new Cisco CCNA 640-802. You are IPv6 (IP version 6) and SDM (Security Device Manager) is based on a GUI easy to configure your routers and switches. One issue is the Cisco 2500 series router IPv6? Yes, they can if they maxed with 16 MB of DRAM and Flash. Here is some information on the Cisco routers and DRAM and Flash, IPv6 support, provided they have the correct IOS. To make life a little easier, I also have a practical minimum of DRAM and Flash, support for IPv6 by the model of platform.

DRAM / flash memory is essential for the functionality of support

IOS Model_________IPv6__________SDM_____________________Max Ver.
Cisco 2500_____16/16 ______Not Available_____________________12.3
Cisco 2600_____64/16 ______Not Available_____________________12.3
Cisco 2600XM__128/32 _____128/32__________________________12.4
Cisco 3620_____64/16 ______Not Available _____________________12.3
Cisco 3640_____128/32 ______64/16 __________________________12.4

If you have a good look at the chart, you also, I note that the conditions to the SDM. As mentioned earlier, Cisco SDM Security Device Manager, the graphical interface and options to configure your router. It is not some of the older models. But the good news of a laboratory perspective is that you need on each router for a good, working as SDM. The Cisco 3640 router is the cheapest way, with 10 MB of SDM-Ethernet and Cisco 2600XM series seems to be the least expensive route, with the SDM-100Mb Ethernet.

Finally, I also have a version IOS column. As you can see above, the Cisco 2500, 2600 and 3620 only supports models 12 / 3, whereas the Cisco 2600XM and 3640 support units 12.4. So if you want that exposure of the latest IOS, the routers in the real world at the moment is that 12.4. But if your budget is not possible, you are still in the routers, the oldest of the 12 / 3 IOS.

Why do you sell routers with storage, can not be IPv6?

Not everyone has the means to support all the features. So werden Sie sehen, dass wir noch bieten Cisco Router 2500-Kits mit 8 MB DRAM and 8 MB Flash in der Lage, um im Hinblick auf den Router, die 85% der Konzepte ist besser als gar nichts, wenn Sie ist knapp Budget bemessen .

How do I know what interfaces and options are available on a router?

In order to prevent and provide a place to compare and interfaces / options I do the next small image to give you an idea of what is expected on each router.

Anything else you recommend?

Well, a number of things. The Cisco 2500 router are awaiting your CCNA studies as long as you correct IOS and memory maxed with all the accessories you need. We can say, but they are only 10 MB of router. It is true, but they still work. The big drawback, in addition to the above lack of SDM and 12.4 is supported, with 10 MB of router that you can not your Inter-VLAN routing laboratories with them (this is the case for each of 10 MB router). It’s as simple as you make at least 100 MB a router for your workshop, you can inter-VLAN, routing, and takes care of this problem and support, the cost of your lab for those with a budget tight!

You want to make sure that your router supports IPv6, because the really do is help Labs IPv6 concepts in sink Finally SDM is most likely the wave of the future, you can begin to do now!

Do I need a switch?

This may be a little discussed several ways. First, some say 80% of the test is based on routing. For that I make. But with only a small error in transmission, not the understanding of change as VLAN, STP and great options, one of the issues is that you, not for your consideration. It is still a few issues, which are based heart as “What is the level 2 of the protocol for a loop-free network?” God thank you, we recorded STP. In other words, it would be good for us to really “see” the transmission of concepts to work. It is indeed, as I read it. A button gives you the opportunity, the button commands and allow you to memorize the syntax and context in which enforcement orders. In addition, you get to make some VLANs Labs. Two buttons, you can see for VTP domain and VLAN information propagate. In addition, you will see the basic unit elections. With three or more, you receive all the counters of these elections and the complete device. Remember that we are only at the CCNA level, so that we now not need a layer 3 Switch 3550 as one. But it is a nice concept your CCNP studies. Finally, you can ask why some of my router Dual-Step kits in them. Now that you can on the section of our site identified, and add the you want to spend part of your kit. The switches do not require issuer, ports and I did not really To Kit with routers. We have some of the greatest kits for both routers and switches in them.

What should I change?

This is one, both a lot of discussion about these days. I will give my opinion on it, and ya cent ways, a laboratory. I’ll give you the information and let you decide how you want your lab.

The Cisco 2950 is a button switch, is tested and the accuracy of IOS commands that you see on the lab. So if you can afford, one, it is good to find. But sometimes, if customers only a budget of $ 200, I can not believe that for it to give up and switch on the router. After all, the test is 80% of routing! Back on the Cisco 2950 is the best for the test button, if you can afford.

But let us say, you can not allow the switches, but a switch, what is next? We have a Cisco 2900 series. This is a step in the Cisco 2950 and supports all the same commands CCNA exam with the exception of port switch and vlan command overall. So with this knowledge, these switches can work for you.

Finally, there is the Cisco 1900 series met. This is not a great demand for them, so very cheap, they are acquired. Some say they have absolutely no value in a CCNA Lab. I tend to not much. You can ask me, hey, what are you smoking? Cisco IOS 1900 series that is not the IOS, which focus on examining how it can be useful? Well, let’s go in knowing that the IOS commands on the 1900 series are not those which relate to the test. Ok, while we are not on them (remember that there are very few counters for CCNA IOS command-assessment with regard to syntax), but concepts that I have a lot of people to a difficult to understand how STP d’oeuvres, as the unit of treatment options and in this way. These terms in exactly the same way on a 1900, since 2950 on the sidelines. Not to mention that you can VLAN, VTP and laboratories on the button to understanding how they work. So I hope you see why I am always to help customers with a bit budget for the exposure to such approaches. * Please note that from January 2009, prices were in 2900 of the series develops seem to be very valuable for us, always the 1900-Switches. The price difference between the two types of switch is so close, it is better for a few dollars extra and 2900 a series of change.

Since I am with the router, I have a function button graphic below to help you choose your Cisco Switch.

With the concept of Network Address Translation (NAT), we can easily assign Internet Protocol address for all computers in large enterprises, some addresses to date. Before we say, they must know the concept of the private IP address and public IP address. Message IP address is a series of addresses that are not for connecting to the Internet. The private internet protocol addresses are below.

10.0.0.0 at 10255255255

172.16.0.0 to 172.31.255.255

192.168.0.0 to 192168255255

The computers of the company and a local network by using private addresses. But with private IP addresses can access the Internet. Thus, the company must be purchased a number of public IP addresses with NAT and it is the private IP address of the existing public Internet Protocol address. Thus, we can avoid the headaches when allocating IP address for all computers in the company. The implementation of losing, we are deprived of Internet Protocol addresses, but we can of the same set of private IP addresses of computers in a network. Thus, the NTA and the concept of access to the Internet Protocol addresses to help us better use of the Internet Protocol address.

Types of NAT

NAT is in the following categories.

1. Static NAT

2. Dynamic NAT

3. Port Address Translation (PAT)

Static, not a NAT (private) IP address is a mark (public) Internet Protocol address. This type of association is a meadow.

Dynamic NAT in a pool of public IP address is a subnet of private IP. This association is not predefined but is dynamic.In Port Address Translation (PAT) is no more Internet Protocol addresses map to a single IP address recorded by several TCP / UDP port numbers

In general, there are 32 bits, the subnet masks, evidently by a block of zeros and a block composed of. In this order, the zeros are used for the part of the host. In the meantime, the mask of “on classful networks 255.255.255.0, 225.225.0.0 or 255.0.0.0. In addition, the Classless Inter-Domain Routing (CIDR) notation is primarily a shorter form that is used for subnet masks. The writing at the bottom, displays the number of the network and the netmask € â„¢ s binary between separated by a slash. An example of this would be 192.0.2.96/24 CIDR.

How to make a subnet mask to determine the part of host and network to an IP address

Using a subnet mask, one can easily recognize the specific network address of a specific IP address. The first, what they should do is implement octal addresses in a binary form. After doing so, they must be a simple bit of action. For example, the octal address for the IP address 156.154.81.56 is implemented as 10011100.10011010.01010001.00111000 while netmask 255,255,255,240 in binary 11111111.11111111.11111111.11110000. Once at the bit and measures on these data, the result is precise 10011100.10011010.01010001.00110000.

The importance of subnet masks over Internet Protocol networks

In the management of an IP network, subnet mask is important, because as a reliable means of communication. The subnet mask and set the IP address are covered network devices to determine if the host from a remote network or a local subnet. In general, a network device sends a request for Address Resolution Protocol “, if you have a local subnet. The purpose of this operation is in fact of the matter systematically € â„¢ s MAC address to relay communications layer Data Link OSI model.

In the meantime, another action happens in general, if a remote network is used. In this case, packages are automatically network devices on the port in the routing table, e-document storage lines to the computer network € ™ s different nodes. If there is no entry in the routing table, especially with the network, a default route is required for packages. If there is no identifiable default route, packets can not be everywhere and easily fall into the process.
