Once the Administrator's user name and password are intercepted by someone with ulterior motives, the consequences will b
As the core device of network communication, Cisco routers are widely used. The following is my experience in practice:
Control port interface practices and connections
Connect one end of the control cable RJ45 in the Cisco2500/1000 series router accessories to the Cisco CONSOLE port, and the Cisco7000/4000 series router
This article describes how to configure a vswitch for a CISCO 3550 router and how to configure access control for a MAC address.
In network management, users often encounter this situation: some users violate management regulations and modify their own IP addresses without permission to access restricted resources. Such behavior not only undermines information security rules, but may also cause network comm
The VPN configuration of the Cisco router is not important for network security, but also makes the user more convenient during use. In this experiment, we use the Cisco 2600 router and the Cisco router VPN configuration to implem
This article describes in detail how to skillfully set the speed limit for commonly used Cisco routers, and provides detailed operation steps. I hope this article will help you.
The so-called speed limit is to set the ACL Access Control List on the router) to block the port used by the Service, so as to prevent the normal operation of the service. For the btsoftware, we can try to seal its port. In general,
Everyone knows that the Cisco router ACL plays an important role in the security policy of the Cisco router. Therefore, it is essential for everyone to master these knowledge points. In fact, this content is involved in many places. Access List) is an ordered statement set. It is a Sort table that allows or rejects pac
The market demand for Cisco routers is still very high, so I studied the knowledge about the default password of Cisco routers and shared it with you here. I hope it will be useful to you. The following are some default initial IP addresses, user names, and passwords used for Factory installation of ADSL, which must be known for debugging.
There are three methods to debug these settings:
One of the most c
The question about the Cisco router interface is described in the following four steps. Based on the demonstration in the image, I believe that we should be able to clearly understand the question about the interface. You can configure a serial interface through a virtual terminal. to configure a serial interface, follow these steps:
1. In Global mode, enter the command "interface serial 0" to enter the ser

Cisco router Entry 1First, let's take a look at the Memory RAM of one of the vro's internal components: Random Access to the memory, which is equivalent to the memory of the computer and is volatile (all storage content will be lost after power failure ), the main software running is the IOS image and configuration file. ROM: read-only memory, which resident some microcodes used to start and maintain basic
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
Huawei router and the same class Cisco router in the functional characteristics and configuration interface is completely consistent, some aspects also according to the needs of domestic users made a good improvement. For example, in English and Chinese can be switched configuration and debugging interface, so that users do not have to face a large pile of Englis
Many people may not have a special understanding of the speed limit of the Cisco router, so I have studied the detailed setting statements for the speed limit of the Cisco router. I will share them with you here, hoping to help you. In a Cisco
Many people are not very familiar with the installation and configuration of CISCO routers. It does not matter. Here we will introduce the classic section of the CISCO router tutorial, this gives you a better understanding of vro configurations. This document uses Cisco2620 as an example to describe the configuration and remote access configuration methods in the
The company's GPS patrol system needs to go WVPDN to communicate, but before looking for a telecommunications took a CISCO2811, collapsed once, the 2811 is the telecommunications sent, the estimated quality is not how, and then to find the company to buy the same type of equipment, 2811 discontinued, on the Cisco 2911.Yesterday arrived Ah, excited a bit, super terminal connected on, looked at the system configuration, the result of the hand is cheap,
