Ccna3 Exploration: Lan Switching and Wireless

Also print out the network diagram on two to three pages so that task information can be read.

1. Move tables and desks 2. Unpack computers and monitors 3. Network computers and printers to the cisco switch. 4.

1. For what purpose is a transceiver used? A transceiver can be used for converting one type of Ethernet connector to another or by converting one type of I/O port to an Ethernet port. 2. This lab connects routers directly to each other via serial cables. Is this a typical configuration? No, By default, Cisco routers are DTE (Data Terminal Equipment)/ DCE (Data Circuit-Terminating Equipment) If not, to what equipment does the DCE end of the serial cable usually connect? If Router A is connected to the DTE end of the cable, Router B must be connected to the DCE end 3. What does a rollover (console) cable look like? Rollover cable is often used to connect a computer terminal to a

All of the sites in the corporation are using the same configuration of workstations, servers, and standalone ups. All of the networks have one way of communicating to the internet and that is by 10base T Ethernet. The bus network is very cost effective to set-up, but it can very difficult to trouble shoot because if the backbone goes down the entire network will have an outage. The other aspect of this network that is a pain is that fact that if two systems are sending a signal, at the exact same time to one another the network will have signal collision, meaning that both signals will drop. In order to prevent this from happening (CSMA/CD) or carrier sense multiple access with collision detection will be set-up. This in effect will put the network into a listen mode to prevent the collisions from taking place..

The work that will be performed will include the design and installation of a fully switched star network. This includes the installation and setup of all the network devices, cabling and interfaces but may be limited to workstations, devices, servers, switches, routers, racks and all related software.

a)As per given Application Working Module we have to use Circuit Switched Network for this Application.because as per given data application needs long time connection and a good bandwidth.if we used Packet switching we have to face some data loss and packet trafficking because there is no end to end connection between source and destination.so the best network is Circuit Switched Network for this given Application.

and service provider, and render a wiring design based on the flow plan of a

A goal of redundant topologies is to eliminate network down time caused by a single point of failure. All networks need redundancy for enhanced reliability. Network reliability is achieved through reliable equipment and network designs that are tolerant to failures and faults. Networks should be designed to reconverge rapidly so that the fault is bypassed.

* Spanning Tree Protocol (STP): Briefly explain the advantages and purpose of the STP. Administrators are having a difficult time placing switch 1 as the root. Provide a sample configuration for implementing SPT on the switches. Choose the mode you feel would be best suited for the environment and justify why. Switch 1 will need to be the root switch in the Springfield topology. Consider any security measures that can be implemented to protect the devices from bogus BPDUs.

In Phase 1, you designed a network switching infrastructure that supported both the existing data traffic, as well as additional camera traffic, according to requirements. In Phase 2, you will create standards and provide a configuration template for implementation teams to use in future deployments.

The last and final problem on the network is the UPS power unit installed at all sites. At this point this may provide enough power to the take care of the current network infrastructure, but this will not work for the new network design. This is vital to the network because, “If a computer is not receiving a consistent flow of electricity, damage can and often does occur.” (Fisher). Providing a redundant power supply will be vital to the network because having the ability to operate when power goes out will make sure that no information or data is

As this demand for dynamic and unpredictable data grows, more and more devices have to be added to existing networks and configured accordingly. The need of the hour is to regulate networks centrally and as a whole rather than configure individual network devices and gain more control to achieve flexibility in existing networks.

Membership in VLAN can be defined based on ports that belong to VLAN. For example, in a bridge with four ports, ports 1,2,4 belong to VLAN 1 and port 3 belongs to VLAN 2.”

RELIABILITY AND AVAILABILITY EVALUATION OF A SYSTEM SWITCHED TO ANOTHER SIMILAR, SUBSTITUTE OR DUPLICATE SYSTEM ON TOTAL FAILURE

The campus redesign we propose that we use all 3 of the Cisco Catalyst 6500 switches and we allocate one switch for the design department, one for the Human resources and one for marketing and sales. This will help optimize and departmentalize the switches for easy access and design simplicity. We also would like to have each switch connected to 2 routers each, this will help with redundency and help take care of the issues that the architects, engineers and employees keep reporting slow response times. To help with internet crashes and speeds we think that the company should
