Cisco Linksys E4200 wireless router

cisco router  Linksys E4200 router is aimed at advanced users, but we nevertheless found it easy to set up and use.

It uses the fastest 802.11n wireless network standard and can work in both the normal 2.4GHz wireless frequency and the less-congested 5GHz frequency simultaneously to improve your in-home signal.

Computers with suitable equipment can connect at even faster speeds but only Intel Ultimate Wifi Link adapters support this at present (see the end of this review for a list of laptops with the adapters built-in).

The two-tone case is discreet: the antennas are housed inside so nothing pokes out, the only part at the front is a white-illuminated logo to indicate status, and even the lights on the four rear network ports can be turned off. It's intended for cable internet users or those with a separate broadband modem with a network socket, so ADSL users will have to use it alongside their existing modems or routers.

It includes the excellent cisco871 Connect software that made setup and configuration easy and provided quick access to the main features. The router can also be used without this software by accessing its configuration pages in a web browser. Previous versions of this program had some annoying quirks but these have now all been fixed.

Running Cisco Connect launches an illustrated wizard that shows users how to plug in the router, and then automatically discovers and configures it. This only took a few minutes, and it worked equally well over wireless or a network cable. Even complete novices should have no trouble getting up and running.

When setup had finished the Cisco Connect main screen let us add computers, printers and other devices to the network. For PCs, an Easy Setup Key containing the router's wireless security details can be created on a USB memory key. Each connected PC can then be assigned parental controls, restricting the times of web access or blocking specific websites.

Another useful feature is the guest wireless network, a separate network that is perfect for allowing visiting friends or family to use the internet while keeping your PCs secure.

There is also a link to the advanced settings that open in a web browser and allow advanced users to configure features such as the USB storage. Any USB disk or memory key can be plugged into the router's USB socket and shared over the network or the internet, but setting this up was not easy and it's a shame it wasn't included in the  cisco 871 Connect software. Disappointingly, you cannot plug a printer or webcam into the USB socket and have it shared.

The E4200 is an expensive router but the fast networking, parental controls and USB sharing are worth paying for.

cisco 3750 switch

In addition to IP-base and IP services feature, the Cisco 3750,3560-X and 3750-X series are supplied with a new LAN Base feature set. The role of three groups available to all Cisco Catalyst 3750-X, 3560-X Series switches are the following:
LAN Base: Improving Intelligent IP services
Baseline: IP Services Business Services: Business Services
Cisco StackWise Plus technology has built a great success, StackWise technology is a leader in the industry, which is a premium stacking architecture optimized for GbE. StackWise technology is designed to respond to additions, deletions while keeping the performance constant. Stack operates as a single switching unit that is managed by a master switch elected from the member switches. Master switch automatically creates and updates all the switching and optional routing tables. The working stack can accept new members or remove existing ones without service interruption. StackWise creates a very flexible system with up to nine individual switches provide simplified administration of a single IP address, a telnet session, a command line interface, the automotive version of the amendment, automatic configuration, and more.
StackWise Plus supports all the features of StackWise and provides backward compatibility with the Cisco Catalyst 3750 Series while improving the turnover of the system up to 64 Gbps. StackWise Plus also allows for local switching in the Cisco Catalyst 3750-X series. Local switch packets coming into a port in the Cisco Catalyst 3750-X series or 3750-E Series Switches for another port on this switch do not have to traverse the stack ring, which will increase the transmission capacity of the switch. Cisco Catalyst 3750-X Series stacks up to nine switches as a single logical unit for a total of 432 Ethernet 10/100/1000 ports with 18 10 GbE ports. Individual 10/100/1000 units can be assembled in any combination to evolve with network needs.
The Cisco Catalyst 3750-X series StackPower Cisco introduces technology, innovation capacity of the interconnection system that allows the power supply in a cell as a common resource shared by all switches. StackPower Cisco unifies the individual power switches installed and creates a group of power to direct that power when necessary. This feature is only available in the Cisco Catalyst 3750-X series switches or IP based IP services feature set. Up to four switches can be configured in a stack StackPower special connector in the back of the switch with StackPower cable, which is different from the StackWise cables available in all Cisco 3560g models.
StackPower can be set to power-sharing arrangements or termination. In a power-sharing state power, all power supplies stacked together and divided by switches in the stack. In redundant mode, where the budget for the total power, calculated on the stack, the maximum power output is not included. This power is in reserve and used to keep the power switches and attached devices, if a power failure occurs, the network operates without interruption. After the failure of a power supply, changes in your StackPower will become power sharing.
StackPower allows customers to simply add additional power to a position in the stack, or to provide redundant power for a member of the battery or simply to add more power to the pool. StackPower eliminates the need for an external redundant power system or the installation of dual power in all stack members.
Catalyst 3750-X and the cisco 3560 Series switches support a voluntary network module uplink ports. The switch configuration by default does not include the uplink module, you can choose four GbE ports (3kx-NM-1G) or network module with two 10 GbE ports (3kx-NM-10G) at the time of purchasing the power switch. 10GbE uplink module has four physical ports and two SFP + ports and two SFP standard. SFP + connector supports both 10GbE and GbE ports, allowing the customer to use the investment SFP GbE and 10 GbE update when business requirements change, without having to do a complete upgrade of an access switch. Uplink module is hot-swappable.
