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
while, when we need to configure the vro, the password may be lost. At this time, we only need a PC (OS is windows series), a console cable and the corresponding interface converter, and we are next to the router. Then follow the steps below to make it easy. 1. Set the Super Terminal of the PC so that we can use the console port of the router to directly operate
Cisco routers use a lot of users, at the same time there will be many problems, the password is forgotten or lost users are very common problems, so I studied the Cisco router password recovery of two methods, here to take out and share with you, hope for everyone useful. When a Cisco
For enterprise users, multi-device port access control can optimize the network more reasonably. Here we analyze in detail how to configure a Cisco router to implement this function. You only need a CISCO router with an asynchronous module or a router with a built-in asynchr
Second, the boot sequence of the routerWhen the router starts, it needs to perform a series of operations, the so-called Boot sequence (boot sequence), which is designed to testHardware and load the required software. The boot sequence includes the following steps.(1) The router performs post (POST) 0 post will check the hardware to verify that all compone

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 classi

During running, RAM contains route table items, ARP buffer items, log items, and groups waiting for sending in queue. In addition, it also includes Running configuration files (Running-config), Code being executed, IOS operating system programs, and some temporary data information. The reading method o

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 routers use a lot of users, at the same time there will be many problems, the password is forgotten or lost users are very common problems, so I studied the Cisco router password recovery of two methods, here to take out and share with you, hope for everyone useful. When a Cisco
Password Recovery principle of the Cisco router-the Cisco router stores several different configuration parameters and stores them in different memory modules. The introduction is as follows: ---- · internal memory type ---- Cisco2500 series routers have five types of memory
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
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
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
The Cisco router has a very high market demand. At the same time, users are not familiar with some features. Here we will introduce some questions about the Cisco Router password restoration for your reference.
How Cisco Router pa
This article describes how to quickly install and maintain a vro from the aspects of control port interface connection, initialization and installation, and troubleshooting and detection of common routing faults. See the detailed description below.
A terminal or PC configured with a Cisco router must also use a valid power supply. Cisco synchronous serial interfa

2. CAR Applicability
A car can only work on an IP packet, but cannot limit non-IP traffic. In addition, a CAR can only be used on a vro or vswitch that supports the CEF switch (Cisco Express Forward. Therefore, only models of Cisco 2600 series and above can use CAR. CAR cannot be used on the following interfaces:
for Cisco's enterprise-class routers and switch products, regular debugging, familiar with the operation of the product principles and business processes. This will be easy to deal with when you encounter the Internet and data failure. The following small series to you recommend the router debugging simple steps:
