Examine the current contents of NVRAM:
Switch#show startup-config
Examine the characteristics of the virtual interface VLAN1:
Switch#show interface vlan1
Switch#show ip interface vlan1
Examine the following version information that the switch reports.
Switch#show version
Examine the default properties of the FastEthernet interface used by PC1.
Switch#show interface fastethernet 0/18
Switch#show vlan examine the contents of the flash directory.
Switch#dir flash: or Switch#show flash

To save the contents of the running configuration file to non-volatile RAM (NVRAM), issue the the command copy running-config startup-config.

First, you will create the new VLAN 99 on the switch. Then you will set the IP address of the switch to
172.17.99.11 with a subnet mask of 255.255.255.0 on the internal virtual interface VLAN 99.
S1(config)#vlan 99
S1(config-vlan)#exit

S1(config-if)#no shutdown
S1(config-if)#exit
S1(config)#
Notice that the VLAN 99 interface is in the down state even though you entered the command no shutdown. The interface is currently down because no switchports are assigned to VLAN 99.
Assign all user ports to VLAN 99.

...Christy Williams University of Phoenix- Profressor Sims Wk 6 Assignment Router & Switch Conf. "Let’s go through the basic steps of setting up a Cisco router to provide Internet access to a small network. I’ll assume you have some basic IOS knowledge, including how to log on and how to save and clear configurations. I’ll also assume that you have a solid understanding of networking, including what Network Address Translation (NAT) is. I won’t cover items such as setting up Secure Shell (SSH) access and hardening access lists. You can expand into those areas as you feel comfortable and want to experiment more. What You’ll Need You need a Cisco router with at least two Ethernet interfaces. An 806, 836, 851, or 871 is ideal for a home or small office setup—in fact, that’s what those models are geared towards. You can buy an 851 for a few hundred dollars from various online retailers. However, a 2610 works just as well, and you might have one sitting in the equipment bin at your office that you can ask to borrow. Your router should have IOS 12.2 or later. This article is based on a Cisco 851W with IOS 12.4, including the IOS firewall feature set. You also need a Cisco console cable (sometimes called a rollover cable). One end has an eight-position, eight-conductor modular jack to connect to the router; the other end has a DB-9 serial connector. In recent......

Switch Configuration

...| Switch Configuration | | | Amanda Robertson | 4/20/2014 | | I was Hired By a company as a network engineer. One of my first jobs was to purchase, install, configure and deploy a Cisco Catalyst 2960-S Series Switches. This is a popular choice with the LAN Base Software, which comes with the switches. I found that this switch would be compatible with the companies needs having 48 ports, POE configurations that offer up to 15.4w per port, USB storage, 10 GB Ethernet uplink flexibility. This switch would use either copper or fiber optic cabling however I would prefer the fiber optic. The first step that I would have to take is to connect all hardware properly. “When you first set up the switch, you should use Express Setup to enter the initial IP information. This enables the switch to connect to local routers and the Internet. You can then access the switch through the IP address for further configuration” (Cisco, 2006-2010). Plug in the AC adaptor cord to the Cisco switch to power it on. The switch will go through POST and then verify that the SYST LED light blinks green rapidly. To run Express Set up mode, hold the mode button for 3 seconds, or when all lights above mode buttons turns green. Connect a CAT5 Ethernet cable to the switch and computer, after 30 seconds launch a browser and enter the IP address 10.0.0.1 in the browser and press enter. I would then fill out all the information requested by the Express Set up Mode, the Management interface......

...03 May 2014 Networking Basics NETWORKS Networks are made up of a basic personal computer, network interface card (NIC), hub, switch, or router. NIC card communicates to the rest of the computer. The NIC card connects the modem to the computer electrically. The NIC has a logic board that relays information to the computer. The NIC card figures out the speed at which information is sent from the computer to the internet. The network can potentially use a hub. Although a hub is rarely used, it divides the connection of a signal between multiple computers. A switch divides multiple computers into separate groupings based on logical or security requirements. The switch usually divide or regroup the computers in the same subnet or local area network (LAN). The router is normally used to transfer data between physical networks. The router transfer the signal to the appropriate place. All this information is transferred around to these different places using a specific language called protocols. Protocols are a format that transmits data between devices. Standards are agreed upon beforehand. For instance, internet protocol version four (IPV4) allows computers to communicate over the internet. (McQuerry, 2008). WAN, LANs, MANs LAN, wide area network (WAN), and metropolitan area network (MAN) are typical types of networks used. LAN is a network that connects computers in small building, offices, and single family homes with network media. LAN can......
