Configuring Switches and Routers
Two vital components in a computer network are routers and switches; however, plugging them in is not nearly enough. In order for routers and switches to operate properly, they must be installed and configured. This is an overview of the proper installation, setup, and configuration of the popular Cisco brand equipment designed to be used with the Ethernet standard of networking.
Switches
The basic configuration includes the configuring of hostname, configuring the enable secret password, enable password and the line vty password and the configuration of each fast Ethernet interface along with the ...view middle of the document...

After an administrator enters the Password Configuration command the next screen will provide the options [M] Modify Password option and [E] Modify Secret password option.
Furthermore, should one switch fail, having another route for data around the failed node ensures the network has no issues. To build redundancy and eliminate the creation of multiple broadcast packets, the spanning tree protocol (STP) must be configured on the network switches. STP allows a switch to recognize which switch on the network is handling broadcast requests from other devices on the network. Without STP, a single broadcast traveling through multiple switches soon becomes multiple broadcasts that render a network unusable (Regan 2004).
According to the document “Understanding and Configuring Spanning Tree Protocol” (2006), the first step in configuring STP is the root switch should always be the switch closest to the center of the VLAN. Once the root switch is determined the following four rules should apply. Rule 1: All ports of the root switch must be in forwarding mode. Rule 2: The root port must be set in forwarding mode. Rule 3: In a single LAN segment, the port of the designated switch that connects to that LAN segment must be placed in forwarding mode. Rule 4: All the other ports in all the switches (VLAN-specific) must be placed in blocking mode. The rule only applies to ports that connect to other bridges or switches.
Routers
When installing a router it is important to take several factors into consideration. The temperature of the area the router will be in should be kept between “32°F - 104°F” (Regan, 2004). Wiring that will be around the router is also a concern, and should be at the appropriate distance from the hardware to insure there is no interference. In addition to the previous considerations, adequate airflow clearances, keeping dust to a minimum, and following proper...

Loading an IOS 4. Loading a configuration file The last three of these steps require the router to copy the files into RAM. Normally, most routers load an IOS image that is stored in flash memory and an initial configuration stored in NVRAM. 2. Routers
