Cisco Catalyst 3750 Series Switches, More Popular, Key Features
The Cisco 3750 Switches are innovative switches that improve LAN operating efficiency by combining industry-leading ease of use and high resiliency for stackable switches. And Cisco 3750 series features Cisco Stack Wisetechnology, a 32-Gbps stack interconnect that allows customers to build a unified, highly resilient switching system, one switch at a time.
For mid-sized organizations and enterprise branch offices, the Cisco Catalyst 3750 Series eases deployment of converged applications and adapts to changing business needs by providing configuration flexibility, support for converged network patterns, and automation of intelligent network-services configurations. What’s more, Catalyst 3750 Series WS-C3750G-48PS-S Switch is optimized for high-density Gigabit Ethernet deployments and includes a diverse range of switches that meet access, aggregation, or small-network backbone-connectivity requirements.
So if you are an enterprise branch office, requiring higher quality network services, Cisco 3750 will be a good choice. Need or not? Please check the following feature details:
Key Features & Benefits of Cisco 3750 Switches
Ease of Use: "Plug-and-Play" Configuration
A working stack is self-managing and self-configuring. When switches are added or removed, the master switch automatically loads the Cisco IOS Software revision running on the stack to the new switch, loads the global configuration parameters, and updates all the routing tables to reflect changes. Upgrades are applied universally and simultaneously to all members of the stack.
The Cisco 3750 Series WS-C3750G-48TS-E stacks up to nine switches as a single logical unit for a total of 468 Ethernet or PoE 10/100 ports, or 468 Ethernet 10/100/1000 ports or PoE 10/100/1000 ports, or nine 10 Gigabit Ethernet ports.
Return on Investment through Lower Operations Costs
The automatic Cisco IOS Software version checking and loading of the global configuration parameters provide the first level of operational time saving. The second level is added during the event of an outage. When you remove a troubled switch from an existing stack of switches and replace it with another switch, the master switch will recognize this as a maintenance outage and automatically reload the port-level configuration that was on the previous switch without user intervention. This allows IT managers to have local personnel in remote locations perform maintenance tasks instead of sending costly technicians out for a few minutes of work, thus saving thousands of dollars in operational costs.
Mix-and-Match Switch Types: Pay as You Expand Your Network
Stacks can be created with any combination of Cisco Catalyst 3750 and Cisco Catalyst 3750-E series WS-C3750G-48TS-S. Customers who need a mixture of 10/100 and 10/100/1000 ports, PoE, and wiring-closet aggregation capability can incrementally develop the access environment, paying only for what they need. When uplink capacity needs to be increased, you can easily upgrade your bandwidth by adding a 10 Gigabit Ethernet version to the stack and upgrade your Gigabit Ethernet links with 10 Gigabit Ethernet on the existing fiber.
Availability: Uninterrupted Performance at Layer 2 and Layer 3
The Cisco Catalyst 3750 switch increases availability for stackable switches. Each switch can operate as both a master controller and a forwarding processor. Each switch in the stack can serve as a master, creating a 1:N availability scheme for network control. In the unlikely event of a single unit failure, all other units continue to forward traffic and maintain operation.
Smart Multicast: A New Level of Efficiency for Converged Networks
With Cisco StackWise technology, the Cisco Catalyst 3750 Series offers greater efficiency for multicast applications such as video. Each data packet is put onto the backplane only once, which provides more effective support for more data streams.
Superior Quality of Service Across the Stack and at Wire Speed
The Cisco3750 Series offers Gigabit and 10 Gigabit Ethernet speed with intelligent services that keep everything flowing smoothly, even at 10 times the normal network speed. Mechanisms for marking, classification, and scheduling deliver best-in-class performance for data, voice, and video traffic, all at wire speed.
Network Security: Granular Control for the Access Environment
The Cisco 3750 supports a comprehensive set of security features for connectivity and access control, including ACLs, authentication, port-level security, and identity-based network services with 802.1x and extensions. This set of comprehensive features not only helps prevent external attacks, but also defends the network against "man-in-the-middle" attacks, a primary concern in today's business environment.
Single IP Management: Many Switches, One Address
Each Cisco Catalyst 3750 Series stack is managed as a single object and has a single IP address. Single IP management is supported for activities such as fault detection, VLAN creation and modification, network security, and QoS controls.

Jumbo Frames: Support for High-Demand Applications
The Cisco3750 Series Switch supports jumbo frames on the 10/100/1000 configurations for advanced data and video applications requiring very large frames.
IPv6 Support
TheCatalyst 3750 Series supports IPv6 routing in hardware for maximum performance. As network devices grow and the need for larger addressing and higher security becomes critical, the Cisco 3750 switch will be ready to meet the requirement.
Standard PoE Support: Graceful Addition of IP Communications
The Cisco Catalyst 3750 and 3750G PoE models support Cisco IP phones and Cisco Aironet wireless LAN (WLAN) access points, as well as any IEEE 802.3af-compliant end device. The Cisco Catalyst 3750 and 3750G 24-port versions can support 24 simultaneous full-powered PoE ports at 15.4W for maximum powered device support. The 48-port versions can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between.
10 Gigabit Ethernet Support: Increased Uplink Bandwidth for Gigabit Ethernet Deployments
The Cisco Catalyst 3750allows network managers to incrementally add IEEE 802.3ae-compliant 10 Gigabit Ethernet connectivity in their wiring closets or grid clusters, further facilitating and enhancing Gigabit Ethernet networks. This provides investment protection to customers who want to use their existing fiber plant, add uplink bandwidth capacity to their switching stacks, and provide higher performance to applications and users.
Management Options
The Cisco 3750 Series switch offers both a superior command-line interface (CLI) for detailed configuration and Cisco Network Assistant Software, a Web-based tool for quick configuration based on preset templates. In addition, CiscoWorks supports the Cisco Catalyst 3750 Series for network wide management.

Routers and Its Role in a Network
The Internet is formed by networks throughout the world interconnecting and passing on data to each other. cisco router make the Internet work by forwarding data using a unified addressing system. They can send information to anywhere in the world as long as that location has an IP address.
Description
Routers vary inside to large expensive machines for commercial applications to small wireless boxes for the home electronics market. A router combines dedicated hardware and specialist software to achieve its task. To be effective, a cisco routers needs to be connected to at least two separate networks because its main task is to forward data from one network to another.
Operation
Routers rely on the Internet Protocol to provide a common addressing system. The protocol defines an address structure which is universally implemented and is enforced by one controlling authority in each country. The IP address of any computer contactable over the Internet has to be unique. The computer sending information over the Internet has to package that data into a packet. The data packet contains a header which includes the IP address of the destination computer. Used routers read this address and then forward the packet in the direction of its destination.
Routing Tables
A router prepares for its work by compiling a list of possible routes to a particular destination. The format of the table does not require that every IP address is listed. They can be noted in groups. When a router is first installed it contacts its neighboring routers. These are the routers to which it is immediately connected. Each of these neighbors send their routing tables to the used cisco routers which then compiles its own routing table. Routers regularly exchange their routing tables and so information about routes held on one router eventually ripples through to all routers in the world.
Algorithm
The routing table contains several different paths to the same destination. The router uses an algorithm to rank these alternatives. There are many different routing algorithms in the world, but they generally all rely on the direction and the distance travelled to reach the target. The distance is often recorded as the number of links the cisco router used crosses. The direction tells the router which of its immediate neighbors starts that route.
Function
Although the routing table contains alternative routes it does not list the routers in the path of that route, only the first router in the chain. The next router receiving the data packet then makes a calculation to decide which of its neighbors will receive the packet next, and so on. This distributed decision making allows used routes to be switched in case of broken connections further down the line of which the originating router is unaware.

Advantages & Disadvantages of IP Phones
Advantage
1. Cost
A primary benefit of Cisco Ip Phone, and a benefit often referenced by IP telephone service providers such as Vonage and Magic Jack, is the reduction of cost for IP telephone customers. Traditional, circuit-based telephone companies have invested billions of dollars over several decades to build out their infrastructure and provide expensive resources dedicated to maintaining voice communications. Because VOIP technology relies on the Internet, rather than an expensive dedicated network, Cisco Phone service providers can charge considerably lower prices than their traditional counterparts.
2. Mobility
With the introduction of modular plugs in the 1980s, traditional telephones began to allow users to move the devices from place to place with relative ease. If the user moved the phone to a different location, though, the telephone would operate with a different telephone number and, depending on the service provider, cp-7945g enable different features. IP phones, by contrast and according to IP product vendor Cisco, register with a central server regardless of their physical location. For this reason, a user can move an IP phone from location to location, state to state or even to another country while still keeping the same telephone number and set of features.
3. Features
Traditional telephone services allow basic features such as call waiting, conference calling, and voicemail and caller identification. According to the Federal Communications Commission (FCC), IP phones typically enable all of these features and a number of others not available in the traditional telephone network. 7945g IP phones, for example, can allow a user to place a call on hold and pick it up from anywhere else with an Internet connection, transfer a call to a telephone on another network, ring incoming calls to several telephones on different networks at the same time and even deliver voicemail messages via e-mail. The specific features offered supported by IP phones vary from phone to phone, cp-7945g= and many may require support from the VOIP service provider.
Disadvantage:
1. Quality of Service
While the Internet-based routing of IP phone calls enables cheap, mobile service, it also moves voice traffic off a dedicated network and onto an ever-changing digital landscape. In the absence of a dedicated set of voice circuits, IP phones typically, according to Cisco, convert voice sounds into data packages, address them to the VOIP switch and send them out across the Internet with no guarantee that they will arrive at their destination. Despite numerous quality of service (QoS) measures implemented by IP phone vendors, used phones VOIP users may occasionally experience a delay in the conversation (latency), poor or robotlike sound quality (jitter) or miss portions of the conversation (packet loss).
2. Internet Requirement
Despite their high mobility, cisco ip phone price must have access to the Internet to work. Because IP phones rely on the ability to connect to the Internet and send data packets, according to Cisco, users must subscribe to a broadband Internet service to use the devices. According to the FCC, this requirement may represent an additional expense to users who do not already subscribe to an Internet connection.
3. Electricity
Traditional telephones require a small amount of electricity to operate, according to service provider CenturyLink, used cisco ip phone but they pull that electricity from a special line card in the telephone company central office. As a result, customers can still use a traditional telephone during a power outage. IP phones, according to the FCC, must draw commercial power to perform their functions and may leave customers without telephone service during a power interruption.

What’s a Router? How does It Work?
Generally, most people are familiar with internet, but have no general idea about router. As a matter of fact, router is related to internet, and vital to net. So what is a used routers, and how it works? Let’s have a look.
Router, a network device that does what it sounds like - it 'routes' data.Routers are devices that allow computers to talk to or connect with other computers as well as other computer hardware.In a simple way, a router can connect a computer to more than one other computer. No matter what type of used cisco routers you have, how it works is what router users concerned. Firstly, look at the following figure, it directly display the relationship between computers and router.
Guide for you to connect a router to computers
1. Ensure that both computers have a LAN (or an Ethernet) card allowing the sharing of files and peripherals. cisco routers used Though all new computers and laptops are equipped with such cards, you may need to buy and attach LAN cards for older models.(A network card is a devised either installed inside a desktop computer or a card that slides into a laptop. A router is the piece that will allow you to receive wireless internetand networking from the devise with the network card installed.)
2. Connect the cable from your Internet Service Provider (ISP) to the Internet port of your used routers. Note that if you have an ADSL connection, your input cable would be a telephone line that needs to be inserted into the ADSL port of the router. For all other connections, you would have a thicker cable known as CAT5 (or CAT6).
3. Take two Ethernet cables and plug them into the Ethernet ports of the router. Note that you will require a router with at least two Ethernet ports to share Internet on two computers. Plug the other end of each of the cables into the Ethernet port of the computers. If you have a router with a single Ethernet port, buy a switch or hub and connect the used router with it (using the Ethernet cable). In turn, the switch (or hub) that includes at least two Ethernet ports will have to be connected to the computers.(More info of switch, hub and router you can visit “Identifying What is Router, Switch and Hub”)
4. Switch on the router and the computers.
5. Configure the router by referring to its user manual. The configuration process defers depending on the type and brand of the buy cisco router.Once configured, you should be able to access Internet on both computers.
More related to router
The router is hooked up between the cable modem and your computer/s.
Buy cisco routers helps block port access into your computer and is a better defense against hackers then a software firewall such as Norton Internet Security or other software firewalls someone might install on their system.
A router is very easy to set up if you read the instruction manual that comes with it.
