In the Cisco router product, we usually need to use restricted access for general users when we initially configure. This is very important for routers, by default, our router is an open system, access control options are turned off, any user can log on to the device for further attack, so we need our network administrator to configure the password to restrict unauthorized users through direct connections, Console terminals and access devices from the
I would like to introduce how to obtain the IP traffic of a Cisco router. Many people may not know how to retrieve the IP address of a Cisco router. 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. A router is a bridge of a computer network and a core device connecting to an IP network. It can not only connect to differen
A Cisco router is a commonly used routing product in large and medium-sized networks. As a core router, It is the soul of the entire network. If the Administrator is improperly set, the security deployment may be taken over by attackers if it is not in place. In that case, all the networks under it will fall, and the extent of its harm is self-evident.

Users using Cisco routing, many of them do not pay much attention to doing Cisco router configuration work, in fact this is a very important part, especially for our network security. There are several ways to do Cisco router configuration. The configuration can be done by the TFTP server over the network, through the menu interface provided at startup, and by th
This article describes how to make the right choice for a CISCO router. Here I will share some of my experiences in choosing a Cisco router. It may be helpful to everyone.
When deploying a LAN, A vro is one of the essential devices. Cisco is the leader in the field of routers and other network equipment. He is also a brand that many network administrators must co
When routers and switches work normally, you do not need to worry too much about wiring issues. However, when the network encounters problems or changes, wiring knowledge may be of great help to you. In this article, we will introduce you to some basic wiring knowledge, and describe the details of the Cisco console dedicated network cable.
The network cable belongs to the first layer of the Network: physical layer. Only the correct network cable can e

Welcome to the network technology community forum, and interact with 2 million technical staff to enter the settings and skills of the two CISCO switches, mainly: Cisco switch setup skills to find the MAC address corresponding to the IP address, cisco switch setup tips: Find the port corresponding to the MAC address on the switch. The IP address of a machine is k
When using a cisco router as an Internet Router, cisco's IP packet filtering function is generally used to count IP traffic. The method is to add the ipaccountingoutput-packets command at each entrance of the cisco router. The cisco router automatically counts the IP traffic of these ports. Common snmp or telnet terminal simulation (showipaccount) methods to obta
After decades of development, from the first four-node ARPANET to the ubiquitous Internet, computer networks have penetrated into our lives. With the explosive growth of the computer network scale, as a router to connect devices also become more important.
When a company builds a network, how to reasonably configure and manage the router becomes one of the important tasks of the Network Manager. This topic describes how to configure a cisco router fro
