CISCO Router Network Address Translation (NAT)Tutorial name: Cisco Router Network Address Translation (NAT) objective: to connect all Intranet IP addresses to the Internet using a small number of public IP addresses. Tutorial Introduction: using NAT technology, when an intranet private address sends data packets to a v

Cisco routers play a very important role in the routing industry, and there are also a lot of user groups. It is very important to understand some Cisco router security configurations. Currently, most enterprises and departments connect to the Internet. Generally, a router is connected to an ISP. This

It is still difficult for general users to implement effective Cisco router nat configuration. So I have studied the comprehensive knowledge about Cisco router nat configuration and will share it with you here, I hope it will be useful to you. 1. NAT introduction: NATNetwork Address Translation) Network Address Transl

Cisco port status: CSU ── channel server unit, DSU ── data server, unit, DTE ── DataTerminalEquipment 1. Serial * is down, line protocol is down (DTE) faults: [1] No power is added to the vro. [2] LINE is not connected to CSU/DSU. [3] hardware error. Solution: [1] Check power supply. [2] Check whether the cables and serial ports used are correct. [3] switch to another serial port. 2. Serial * is up and line protocol is down (DTE) faults: [1] local or

A router is a commonly used network device. How should we configure VOIP implementation? What are the specific operation steps? The following article will give you a detailed introduction. Using the Cisco router configuration can easily implement VoIP, So I studied the statements related to the Cisco

Global debugging When configuring a Cisco router, the boundaries between global and interface commands are obvious. In this case, we use "Global" to identify commands that cannot be used for interface debugging or specific transmission media types and Protocol debugging. For example, in vrouters 2500, you can use Debugging commands to analyze the Cisco Discovery

RIP and IGRP are commonly used router configuration protocols. What problems should we pay attention to when configuring RIP and IGRP? What should we do? The following configuration steps provide detailed answers. RIP Protocol RIP (Routing information Protocol) is an Internal Gateway Protocol (IGP) that is widely used earlier and is suitable for small-sized similar networks, is a typical distance-vector protocol. For more information, see RFC1058 an

1. Preparation Tools Cisco TFTP server, HyperTerminal, iOS files iOS files are not easy to find, you need to look at the hardware version, as well as the size of ROM RAM, to my Cisco 2621XM for example (with two fastethernet),Start looking for a few 2600 of iOS, the brush is not correct, the problem of unrecognized network interface, can not be configured, there should be F interface with S Ios,

Currently, Cisco routers have become a leader in the routing industry. Many people may not understand the configuration steps of Cisco routers. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. The company is headquartered in Beijing and has three branches nationwide. It is required that data in four locations be queried i

CHAP (Challenge Handshake Authentication Protocol) and PAP (Password Authentication Protocol) are generally used to provide security Authentication on PPP encapsulated serial lines. With CHAP and PAP authentication, each Cisco router is identified by a name to prevent unauthorized access. Task commands Set the PPP encapsulation ppp1 Set the authentication method ppp authentication {chap | chap pap | pap cha

This article describes how to control the BT traffic of a Cisco router through specific operations, and describes the specific operation methods in detail. I hope this article will help you. Network-Based Application Recognition (NBAR) indicates Network Application Recognition. NBAR is a technology that can dynamically search for protocols in Layer 4 to Layer 7. It can not only control static and simple net

are used The route of this packet. ---- GRE only provides encapsulation of data packets. It does not have encryption to prevent network listening and attacks. Therefore, in the actual environment, it often corresponds to an IP address. When the SEC is used together, IPSec provides encryption of user data to provide users with better security. The GRE protocol has two main purposes: internal protocol encapsulation and private address encapsulation. In China, CEN uses almost all TCP/IP protocols,

Probably a lot of people on the Cisco router speed limit is not a special understanding, so I studied the Cisco router speed limit detailed settings statement, here to share with you, I hope to be useful. In a Cisco router device,

CISCO router device categoryThe name rules of cisco routers start with cisco, such as cisco2611 and cisco2610. cisco is the name of the device manufacturer, 26xx represents the 2600 series routers, and xx is a more detailed classification. The following lists several common

There are a lot of users using Cisco routers, So I studied the global debugging of Cisco routers and shared it with you here. I hope it will be useful to you. When configuring a Cisco router, the boundaries between global and interface commands are obvious. In this case, we use "Global" to identify commands that cannot

In addition to address binding, ARP configurations of Cisco routers are getting more and more attention. Therefore, we will discuss two aspects here. It seems a bit messy, but I hope it will help you. I know that the command for binding the IP address of the cisco router to the mac address is arp IP address, mac address, arpa, but I think there should be a comman
