Nt1310 Unit 2 Case 6.1 Unmanaged Switch

Flexibility and Scalability – VLANs remove the physical boundaries of a network. Users and devices can be added or moved anywhere on the physical network, and yet remain assigned to the same VLAN. Thus, access to resources will never be

Network switches are deployed throughout the enterprise. They are used to distribute data and provide LAN connectivity to end users. Without the network switches, systems will not be able to communicate with servers and applications. All devices are managed. Managing network devices is critical to any organization. It allows

Individual users play an important role in any form of institution or organization but concerns are raised about the security. The network administrators clearly lay down a set of rules, regulations and protocols that an individual user has to agree accordingly upon which part of the resources and what class of service that the user can obtain.

In order to mitigate these risks, it is imperative network switches are hardened. Additional controls may include ARP inspection, disabling unused ports and enforcing effective security on VLAN’s to prevent VLAN hopping.

6. Why is Ethernet technology more appealing to users than the rest of the LAN technologies?

The definition of a switch or network switch is a small device that joins multiple computers together, working on layer two of the OSI, to form a local

Bus – All computers and devices are connected asynchronous to one linear cable known as a trunk or generally known as a backbone. each ends of the trunk should be terminated to prevent the signal from bouncing duplicate the cable. as a result of the network

I choose the devices needed for the new implementation: Cisco Catalyst 6500 router and 2800 series four switches will be utilized. Here is the cost of effective access switches that are capable of VLAN, DTP, DHCP, RSTP, PoE, and furthermore, price can range from $1,400-$3,500 dollars each. These switches offer integrated security including network control and quality service, they also offer redundancy to provide and deliver intelligent services for a networking edge. Therefore, they include flexibility in the routing series as increased port density which could induce a rapid growth in networks without any additional cost at any time. However, the more capacity a device may have the more beneficial it will be to the administrator user, when setting up any secure measures throughout the configuration process of vlans and networks. The network accessibility will be ensured throughout the provision of redundancy of routers throughout the xACME network on each site or trade school. Although, optic fiber cables will be used to connect all layer 2 and 3 switches and servers, spanning tree protocol will be set on switched to address to eliminate any bridging loops from entering into any

In the seven layers of the OSI, control is passed between layers. The model is theoretical, but tells us how a network takes the data sent from the application all the way down to the physical layer and out, to in the physical layer and back up all the way to the application layer. This Model has nothing to do with the actual functions of the process. Instead it is a concept of the framework, so the complexities of a network can be broken down and understood (Beal, 1999).

The Ethernet lines run from the network switch, sometimes through a patch panel, out of the communication room and connect to the VoIP phones and other IP devices. Adding PoE enables devices to be powered over the same Cat 5 cabling infrastructure, providing the most cost-effective solution. Allows users too freely and safely mix legacy and PoE-compatible devices on their network. PoE technology is designed in a way that does not degrade the network data communication performance or decrease network reach. There are two ways to implement Power over Ethernet: endspan and midspan. A VLAN allows a network of computers and users to communicate in a simulated environmentas if they exist in a single LAN and are sharing a single broadcast and multi cast domain. The purpose of implementing a VLAN is to

3: Network Layer: The use of network layer is switching and routing technologies. It demonstrates logical path and virtual circuits for transferring data from one node to

All main networking, router, switches and servers will be in a closet that is only accessible to the networking team, this way it’s not

It provides the hardware means of sending and receiving data on a carrier, including defining cables, cards and physical aspects.

Another thing about this switch is, it has 4 fiber optic ports rather than the 48 Gigabit Ethernet ports. By these 04 ports we can create hi speed uplinks. Also this has 48 ports. That means rack space also can save.

LAN Switch- A LAN Switch performs the same work as a hub except that, a switch does not broadcast packets to every computer in the network like hubs. All the computers and computer devices will be connected to the switch by Ethernet cables. The LAN Switch costs $150.
