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

A Cisco router is a network device that connects multiple networks or CIDR blocks. It can translate data from different networks or CIDR blocks ", so that they can "read" each other's data to form a larger network. A vro consists of hardware and software. The hardware is mainly composed of physical hardware and circuits such as the central processor, memory, interface, and control port. The software is main

When a Cisco router forgets or loses the enable password, there are two ways to recover, depending on which series of routers you are using. The first of these methods This approach restores the following routers: Cisco 2000 series, 2500 series, 3000 series, Cisco 4000 series using the 680x0 Motorola CPU, and 10.0 se

This article describes how to enhance the security of a Cisco router by using a Nipper. So how should we use it? The following article gives you a detailed answer. How do I use a Nipper? Since Nipper supports so many devices and is also known to support a wide range of multi-functional options, it is impossible for me to present them in all aspects. However, we can make a basic demonstration. In our example

Enable resolution by IP NAT without setting the direction---this way can be accessed directly from the public IP address, or can be accessed by domain name method---unfortunately Cisco is different iOS, some although have IP nat enable, but do not re

Necessity for configuring WRED on a Cisco Router Although the queue provides VoIP QoS congestion management, it still needs some congestion avoidance mechanisms, such as WRED. In particular, WRED can prevent the output queue from reaching the limit value, which will lead to the loss of all input packets. This article comes from Informit and discusses the necessity of configuring WRED on a

I have learned some useful questions about the password of a Cisco router. So I have studied how to use the password to protect a Cisco router. I would like to share it with you here and hope it will be useful to you. The most serious cause of security problems is often because people ignore the most basic security mea

Cisco once again launched a new generation of router products and also applied new technologies. So I studied how Cisco developed the new VQE technology to solve the problem of IPTV Video Delivery. Here I will share it with you, I hope it will be useful to you. Cisco has announced the release of the VisualQualityExperi

Cisco IOS is a dedicated kernel that provides routing, switching, network interconnection, and remote communication capabilities. Most Cisco routers are running iOS, and more and more Cisco Catalyst switches are running it, including Catalyst2960 and Catalyst3560 series switches. Some important aspects of the Cisco

principle, using a Udpecho request instead of a ICMPECHO request to initiate an attack. While cyber security experts are focused on developing devices that block Dos attacks, they have little effect because Dos attacks exploit the weaknesses of the TCP protocol itself. Properly configured routers can effectively prevent Dos attacks. In Cisco routers, for example, the iOS software in Cisco routers has many

In Cisco router configurations, NAT configurations are frequently used. I hope the introduction below will be helpful to the majority of fans. It is a common method. The vro performs simple NAT translation and sets a CIDR Block in the NAT address pool. After a while, I found that the address pool was a waste of time. When I wanted to use a real ip address, I couldn't use it, so I decided to modify the
