Method Status Protocol GigabitEthernet0/0 192.168.40.254 YES NVRAM up up Answer: The problem is that either the IP address is wrong or the subnet mask is wrong. That is because the 192.168.40.9 IP address is not in the same subnet as the default gateway IP address (192.168.40.254). Changing the subnet mask to 255.255.255.0 or changing the IP address to 192.168.40.129 – 192.168.40.253 would resolve the problem. The ping command can be used to check for connectivity, and it was. The tracert command could have been used to see where the ping failed. Scenario 2: One user complains of lack of connectivity to certain resources outside of their directly connected network. The output of the “ipconfig /all” command is below. The IP address configuration for that interface on the router for that segment is also...

...are manually configured by using the switchport port-security mac-address mac-address interface configuration command, stored in the address table, and added to the switch running configuration. Dynamic secure MAC addresses-These are dynamically configured, stored only in the address table, and removed when the switch restarts. Sticky secure MAC addresses-These are dynamically configured, stored in the address table, and added to the running configuration. If these addresses are saved in the configuration file, when the switch restarts, the interface does not need to dynamically reconfigure them. You can configure an interface to convert the dynamic MAC addresses to sticky secure MAC addresses and to add them to the running configuration by enabling sticky learning. To enable sticky learning, enter the switchport port-security mac-address sticky interface configuration command. When you enter this command, the interface converts all the dynamic secure MAC addresses, including those that were dynamically learned before sticky learning was enabled, to sticky secure MAC addresses. The interface adds all the sticky secure MAC addresses to the running configuration. The sticky secure MAC addresses do not automatically become part of the configuration file, which is the startup configuration used each time the switch restarts. If you save the sticky secure MAC addresses in the configuration file, when the switch restarts, the interface does not need to relearn these addresses. If you...

...implemented features of Cisco router and switches by using a simple, small office scenario as a case study. Typical of a small organization is there are departments for financial matters, marketing and sales and one or more managers. The personnel in each of these areas has specific computer functions and data needs with some being in common such as Internet access and others being necessarily limited to certain workers such as access to financial data. Let’s assume we’re a consulting firm that’s been hired to design this network and as the the first step we have met with the key managers to develop a list of criteria for each department in regards to computer resources, security and performance. In our meeting we agreed to the following goals. Network Design Goals and Numbers Overall: A reasonable level of network security. This particular business isn’t subject to any set of specific regulations such as HIPAA but management well understands that good security practices are both a sound investment in protecting the company’s IT assets, the company image and as a deterrent against legal proceedings. It was agreed that the following basic security procedures are to be implemented. - Centralized anti-virus on a server that can “push-out” anti-virus software to all client machines on the network and can monitor and update those clients as needed. - Only those services that are required in general will be permitted to pass through the various router interfaces and all others will...

...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 transmit...
