Creating Vlans, first determine the ports range for each vlan?
If 3 vlans are to be created:
>> A Switch has ports from fa0/1 to fa0/24
>> Assign port ranges to each vlan:
1. Vlan 10 has fa0/2-7 (suppose net-id is: 10.0.0.0)
2. Vlan 20 has fa0/8-12 (suppose net-id is: 20.0.0.0)
3. Vlan 30 has fa0/13-18 (suppose net-id is: 30.0.0.0)
>> Reserve fa0/1 for switch-to-router connection and fa0/24 for switch-to-switch connection. Set trunk mode to both these ports early on:
* Go to the switch.
* Go in Enable mode and Configuration Terminal.
* Write for both reserved ports the following:
* Int fa0/1
* Switchport mode trunk
* Exit
* Int fa0/24
* Switchport mode trunk
* Exit
>> Now create vlan on the switch:
* In switch’s config terminal
* Write vlan <vlan id> in this case we have vlan 10
* Do the following:
* Vlan 10
* Name HR
* Vlan 20
* Name admin
* Vlan 30
* Name office
>> Once the vlan ids are created. It is time to set their interfaces for the port ranges we just mentioned at the top.
* Inside switch’s config terminal
* Write int range fa0/2-7 (in this case for vlan 10). Do the following
* Int range fa0/2-7
* Switchport mode access
* Switchport access vlan 10
* Exit
* Int range fa0/8-12
* Switchport mode access
* Switchport access vlan 20
* Exit
* Int range fa0/13-18
* Switchport mode access
* Switchport access vlan 30
* Exit
>> Now we have set the interfaces for the ranges of vlans. Simply provide the IP addresses to all the PCs connected with the switch (make sure you check the ports of each switch-to-PC connection).
>> You can only ping within one vlan. Vlan-to-Vlan ping is restricted.
>> Connect…...

... designed to provide automatic distribution of definitions at the core switch to the distribution switches. This feature allows the client to define once the VLANs at the core switch and have the VLAN definition automatically recreate to all of the other distribution switches for the network. After the VLAN definition has been completed, it is then possible to assign ports to the VLAN (Regan, 2004). There are many benefits of a VLAN. The main benefit is that the physical boundary is removed with careful planning during the implementation of the installation. The Enumeration of a VLAN Implementation Plan involves the following: * To define the LANs membership * Determine what is the best method for communicating the VLANs information of the members through the multiple switches * Differentiating and Creating the Workgroups * The Automatic Configuration * The Mapping between Virtual connectivity and Physical connectivity * Ensure the configuration of consistency * The traffic analysis and control with the VLAN Using all of the factors listed above, either a network expert or engineer is able to find the best method to use for the implementation of a VLAN that is based on the infrastructure of the company desired grouped network.

Creating Value in Marketing

...Marketing has been defined differently by different people. On the face of it, it may be thought of as the process by which an organisation reaches out to the consumers with the products or services that it has to offer in order to make profits. If we dwell deeper, it's worth mentioning that marketing strategies have evolved immensely over decades. The organisations in the present day care as much for creating value for customers as they do for increasing their profits. Infact, it has been largely accepted that both these things are interlinked. Modern age marketeers are realising and understanding the importance of creating value for their consumers so as to reap the benefits out of a strong buyer-seller relationship. This can be supported by Gary Armstrong who quotes that "creating customer value and satisfaction are at the very heart of modern marketing thinking and practice." The need and importance of creating value has been discussed in the following paragraphs. The ways in which organisations create value for their consumers as well as themselves has also been highlighted with examples from the products and services we use/see in our everyday lives. Also, the role of value creation in today's market has been illustrated with examples from the telecommunications sector, fashion sector ............................. What exactly does creating value for the customer mean? To understand this better, let us go back to the role of marketing. Marketing strategies...

Vlan Virtual Local Area Network

...VLAN Virtual Local Area Network Introduction: A VLAN (Virtual Local Network) is a network of computers that behave as though they are connected to the same wire even though physically they may be located on different segments of the LAN. VLAN are configured through software rather than hardware. This is a big advantage to VLAN because that makes it flexible and when moved physically it can stay on the same VLAN without any hardware configuration. (http://www.webopedia.com) A VLAN has three major functions: 1. Limited the size of broadcast domains. 2. Improves network performance. 3. Provides a level of security. VLAN Switched Port and Configuration: Using a switched VLAN will allow you to create groups of logically network devices that act as though they are on their own independent network. And this includes if they share a common infrastructure with other VLANs. When you configure a VLAN, you must sign it a number ID and you also have the option of name it. The purpose of VLAN implementations is to associate ports with particular VLANs. You configure the port to forward a frame to a specific VLAN. A port can be configured to support these VLAN types: Static VLAN, Dynamic VLAN, and, Voice VLAN.

Successful entrepreneurs are opportunists who, through their creativity, drive and vision, create economic or social value. They challenge conventional wisdom by practicing disruptive innovation — innovation that creates new markets through the application of a different set of values. They change the rules of the game by questioning the status quo and upping the stakes. It follows that an entrepreneurial organization can be defined as: An organization that places innovation and opportunism at its heart in order to produce economic or social value.

...VLAN - Benefits and Limitations Introduction The purpose of this walkthrough is to provide a better understanding of Virtual Local Area Networks and their use in the networking world. In the following sections, I will define a VLAN and describe its benefits as well as some limitations. I will explain why it is important for a network administrator to understand VLANs, and give some basic instructions to determine how many VLANs a department would typically need. Finally, contact information will be provided for any additional questions you might have. Use of this information will be used to determine a department's VLAN needs. If VLANs are well thought out in advance, the need to readdress devices and modify VLAN configurations more than once will not become an issue. This will save everyone involved a great deal of effort and minimize the amount of changes that will be needed. What is a VLAN? Virtual LANs can be viewed as a group of devices on different LAN segments which can communicate with each other as if they were all on the same physical LAN segment. Switches using VLANs create the same division of the network into separate domains but do not have the latency problems of a router. Switches are also a more cost-effective solution. By now you are probably wondering why someone would go to all this work to end up with what appears to be the same network as the original one. In many instances, LANs have been grouped with physical location being the...

The first contributing factor was the executives were afraid of losing their power and authority they had. I believe they knew by developing a Enterprise Project Management Methodology, that only one executive would be in charge and more powerful than the other executive's. The executives new at some point they would have to do it, but what they did not understand is by not developing an Enterprise Project Management Methodology they were putting the company’s growth and competitiveness in jeopardy. The second contributing factor was the executives had no clue on were to begin with developing an Enterprise Project Management Methodology. The executives were so afraid of who was going to be in control that they really never thought it out. The executive staff recommended 12 life cycles which would have increased paper work and less time to manage the project. A consultant was called in to assist them in creating an Enterprise Project Management Methodology explaining the pros of having.

...Assignment: VLAN By creating a Virtual Local Area Network (VLAN) for this company it would best fit their needs. Because the benefits of a VLAN are numerous, this would include decreased bandwidth usage, increased security and separation of location. Where the member user of a VLAN they do not have to be in the same location to be able to share resources. To reduce the network congestion it will be split logically into broadcast domains, this will increase to security. Then the different section of the network will be divided by the group functions which would include Marketing, engineering, operation and the call center each department will have their own section. By splitting the network in sections for each department, it will make the network more secure through compartmentalization. The segments will be logically divided from the rest of the network, access then can be restricted between the segments. By controlling access to indivual segments is going to be the best way of better security, this is going to be accomplished by creating user groups for each of the different segments. By creating a VLAN this will ensure the Marketing department will have access to the resources needed. This will also apply to the other departments and it will provide the security around the data that needs to be protected. By going with a Port assigned based VLAN the different groups are used to facilitate any future reorganization of the physical network layout will made...

Creating an Agenda

...Creating an Agenda Chris Abernathy SOC/110 John Koehler Creating an Agenda More and more meetings are now and will continue to be conducted without the benefit of being in the same room together. People are working from home or the other side of the planet, and it’s important to make these virtual meetings effective. Virtual meetings, which I define as anytime we discuss something with two or more people outside of the same room, can be done over the phone or on the web. And though there are many advantages to meeting with people in this way, there are also obstacles to making them work well. According to "Working In A Virtual Team" (n.d.), it is more difficult to fully understand each other because even the use of video can hide a great deal of non-verbal communication. We also interact differently when we’re not in close proximity to one another. Distractions abound and can easily be hidden from others. And the ability to build trust and camaraderie are especially difficult. All Meetings Should Include: * Agenda. Nothing frustrates people more than attending a meeting where there is no clear reason for it and no logical progression of topics to be discussed. * Check–in time. Take five minutes or so in the beginning for everyone to say something about what’s going on with them—professionally or personally. This gets everyone talking right away and helps facilitate camaraderie. * Schedule. Start and end the meeting on time, and keep the agenda moving...

The Knowledge Creating Company

...The knowledge creating company Nowadays, we know that in the world of business, to achieve success is not as easy as we may think, and uncertainty is always rounding our expectations. But there’s one thing we know for sure, knowledge can be the tool we need to take advantage of. When we refer to knowledge, we are not saying that just having the knowledge can be the right way of going through with a business. Knowledge is a tool that has to be well used, spread and though within all the organization. The key point is to be able to make all the organization subjective knowledge and ideas, into real information available for everybody. At first, is important to make all of the organization understand and embrace that commitment should be equal from everyone working there. When a person is committed with an organization, that person will identify himself and feel part of it. One of the hardest things is to be able to make all the ideas and subjective knowledge that emerges from the organization go from tacit knowledge to actually explicit knowledge. For this problem there are few interesting points and blueprints that can be used to make all these ideas into available information. Take as an example the insights. When people is making insights of something, tacit knowledge starts to come out in the form of ideas, which later on can be expressed or understood easily. Facing problem is a very good way to develop explicit knowledge. We are told that there are few tools to...

Marketing is on the first floor, engineering is on the second floor, operations is on the third floor, and the call center is on the fourth floor. The LAN is organized neatly, with each floor having its own switch. Some groups on the floor are connected through hubs and the network is planned for orderly growth. The company grows faster and much differently than planned, however, and the call center must be expanded. Some engineering employees on the second floor and operations employees on the fourth floor move offsite and the call center expands. Space is compressed and users move to other parts of the building, but their communities of interest do not change. The same users still need to communicate with the same services. Explain, in a 350- to 700-word plan, how a virtual LAN (VLAN) could be implemented so bandwidth is not consumed. Your plan must ensure that the network is not flooded with packets, and that members of the same VLAN can be located in different buildings or cities.

Hrivnak Elena Rozkov Human Resources Training and Development April 12, 2012 MGMT 3060 CREATING DISCIPLES: THE TRANSFORMATION OF EMPLOYEES INTO TRAINERS 1 After our class discussion and reading article “Creating Disciples” again, I have a better understanding of the process and importance of the training program, which is designed for developing and supporting employee trainers, but I still cannot completely agree with the authors’ model. Martin & Hrivnak (pg.614) are talking about turning novice employees into trainers if this employee feels strongly enough about the idea to volunteer to teach other employees. But they are not talking about rewards, recognitions or promotions. According to Martin & Hrivnak (2009) an organization has to follow the “why” and “how” approach, and needs to understand the benefits and disadvantages between hiring an insider or an outsider to train others. Deciding which trainer to choose depends on the objectives of the program and how valuable they will be for an organization. By turning employees into disciple trainers will benefit the company in many ways. The insiders are cost-effective for the company. Also, training process can be easier because trainers will be accepted by their peers, which will lead to a comfortable work environment. Trainers can relate to other employees because they are already in...

Vlan

...VLAN When setting up a VLAN you have to look at the benefit of having a VLAN. The benefits of creating a VLAN are flexibility, performance improvement, and savings on cost. With flexibility you can move users to new locations without reconfiguring the system. The VLAN improves performance by segmenting broadcast traffic into port groupings, this helps to preserve network bandwidth and save processor time. The last benefit is cost savings; VLANs will eliminate the need to use routers to partition LANs into multiple broadcast domains, thus reducing hardware costs. Let’s look at the security aspect of a VLAN; one way to improve security with the VLAN is by isolating groups. High-security users can be grouped into a VLAN, possibly on the same segment, and no users outside that VLAN can communicate with those users. Using a VLAN membership that is port assigned based will be used to help future reorganization of the physical layout of the network. This will help if there is relocation or reallocation since there will be a centralized administration of the network and the users of the network. This choice will provide for simpler administration than MAC address, User ID, or Network address VLAN membership when it comes to the placement and changing the personnel assignment of the groups (Regan, 2004). Now let’s talk about layers. You would think that since VLANs are created on Layer 2 switches that this would be the best layer to utilize, but using the layer 3 switch...
