Part II: Cisco IOS Tips and Tricks
Timestamping Messages
When the router displays log or debug messages, it defaults to showing you how long the router had been up when the event occurred. Many times, it is more helpful instead to know the date and time when the event occurred. The command for this is service timestamps [log | debug] datetime localtime in global configuration mode. If you use this mode of logging, you should set the clock and date as shown in the next section.
Example:
Router(config)#^Z
Router#
00:39:40: %SYS-5-CONFIG_I: Configured from console by console
Router(config)#service timestamps log datetime localtime
Router(config)#^Z
Mar 2 15:47:04: %SYS-5-CONFIG_I: Configured from console by console
Setting the Clock and Time Zone
You can set the clock on the router with the privileged mode command: clock set . When issuing this command, you must use the actual name of the month, not its number.
You may also want to set the time zone and daylight savings time adjustments. This is done in global configuration mode. The commands are: clock timezone , and clock summer-time recurring.

Part I: Cisco IOS Tips and Tricks
Auto-Completion of Commands
When typing a command, it is only necessary to type enough letters to make the command unique at your current configuration mode. Once you have enough letters that the IOS can understand what command you mean, you can stop typing. Type a few letters, then press the TAB key – if the router understands the command, it will complete it for you. If the router doesn’t understand the command, type another letter or two, press TAB again, and see if that’s enough. Typing fewer letters per command speeds up your configuration, and creates fewer changes for typos!
Disable DNS Server Lookup
When you type something (at the user or privileged prompt) that the router doesn’t recognize as a command, it assumes that you want to telnet there. So it telnets there if it’s an IP address, or looks in the config for a host table if you typed a word. If the word can’t be resolved to an IP address via a host table, the router broadcasts for a DNS server. This is good if what you typed was an IP address or host name that you want to telnet to – it means you don’t have to type the word “telnet.” This is bad if you just mistyped a command. It ties up the router until the DNS request times out. You can turn off the DNS request with the command no ip domain-lookup at the global config mode.

The Evolving Network Model - The Hierarchical Design Model
Cisco used the three-level Hierarchical Design Model for years. This older model provided a high-level idea of how a reliable network might be conceived, but it was largely conceptual because it didn’t provide specific guidance. Figure 1-1 shows the Hierarchical Design Model.

The Application Layer
The Application layer of the OSI model marks the spot where users actually communicate to the computer. This layer only comes into play when it’s apparent that access to the network is going to be needed soon. Take the case of Internet Explorer (IE). You could uninstall every trace of networking components from a system, such as TCP/IP, NIC card, and so on, and you could still use IE to view a local HTML document—no problem. But things would definitely get messy if you tried to do something like view an HTML document that must be retrieved using HTTP or nab a file with FTP or TFTP. That’s because IE will respond to requests such as those by attempting to access the Application layer. And what’s happening is that the Application layer is acting as an interface between the actual application program—which isn’t at all a part of the layered structure—and the next layer down by providing ways for the application to send information down through the protocol stack. In other words, IE doesn’t truly reside within the Application layer—it interfaces with Application layer protocols when it needs to deal with remote resources.

The OSI Reference Model
One of the greatest functions of the OSI specifications is to assist in data transfer between disparate hosts—meaning, for example, that they enable us to transfer data between a Unix host
and a PC or a Mac.
The OSI isn’t a physical model, though. Rather, it’s a set of guidelines that application developers can use to create and implement applications that run on a network. It also provides aframework for creating and implementing networking standards, devices, and internetworking schemes.

Models Networking
When networks first came into being, computers could typically communicate only with computers from the same manufacturer. For example, companies ran either a complete DECnet solution or an IBM solution—not both together. In the late 1970s, the Open Systems Interconnection (OSI) reference model was created by the International Organization for Standardization (ISO) to break this barrier.
The OSI model was meant to help vendors create interoperable network devices and software in the form of protocols so that different vendor networks could work with each other. Like world peace, it’ll probably never happen completely, but it’s still a great goal. The OSI model is the primary architectural model for networks. It describes how data and network information are communicated from an application on one computer through the network media to an application on another computer. The OSI reference model breaks this approach into layers.

Networking Basics
Before we explore internetworking models and the specifications of the OSI reference model, you’ve got to understand the big picture and learn the answer to the key question, Why is it so important to learn Cisco internetworking?
Networks and networking have grown exponentially over the last 15 years—understandably so. They’ve had to evolve at light speed just to keep up with huge increases in basic missioncritical user needs such as sharing data and printers as well as more advanced demands such as videoconferencing. Unless everyone who needs to share network resources is located in the same office area (an increasingly uncommon situation), the challenge is to connect the sometimes many relevant networks together so all users can share the networks’ wealth.

Access Control Lists (ACLs)
ACL is simply used to allow or not the package from the hosts toward a particular goal. ACL consisted of rules and conditions that determine the network traffic and determines whether the router will process the packet will be passed or not. This module will explain the standards and the extended ACL, ACL placement and some applications of the use of ACL.
ACL is a list of conditions used to test the network that tries trfaik through a router interface. These lists tell the router where packets will be accepted or rejected. Acceptance and rejection based on certain conditions.
To filter traffic jaringa, ACL determines if the packet is passed or blocked at router interfaces. Router ACL to make decisions based on source address, destination address, protocol, and port number.

Routing and routing protocols
Routing is the process whereby a router to forward packets to the destination network. A router makes decisions based on the IP address that is addressed by the package. All routers use the destination IP address to send packets. In order routing decisions are correct, the router must learn how to achieve goals. When routers use dynamic routing, information learned from other routers. When using static routing, a network administrator to configure the information on the network you want to target manually.
If static routing is used, then the configuration must be performed manually, the network administrator must insert or remove a static route in case of topology changes. On a large scale network, if still using static routing, it will be a huge waste of time network administrators to update its routing table. Therefore, static routing is only possible for small-scale networks. While the bias is applied in dynamic routing of large scale network and requires more skills than administrators.

WAN and Router
Wide Area Network (WAN) is a data communications network that connects users in a network that is in a large geographic area. WAN has several important characteristics that differentiate it from the LAN. In the first lesson in this module will discuss the introduction of WAN technologies and protocols. And will also explain how the similarities and differences between the WAN and LAN.
It is very important to understand the physical layer components in a router. This knowledge base will add the information and capabilities that will be required to configure the router and set the routing network. This module also describes the technique of the physical connection of the various interfaces.
WAN is a data communications network, spread on a large geographic area like a province or country. WAN always uses transmission facilities provided by telecommunications companies such as telephone service company.

History Cisco
Around the 1980s, a married couple Sandy Lerner and Len Bosack, they both work in different depatement at Stanford University. There are obstacles in the communication between them, then this couple created a gateway server that uses IP protocol in the living room can make it easier for computers from the two department from being able to communicate with each other. They were eventually established cisco systems (note the small c) in 1984 by launching a small commercial gateway which in turn can change the world of networking. In 1992 the company was changed to Cisco Systems, inc.
