With the development of China's routing industry, its market demand is also increasing. As a leader in the routing industry, Cisco routers have a very high market share. Telnet to the Cisco router for remote management is the choice of many network management, but the data transmitted through Telnet is in plain text, so this login method has a great security risk
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

customized within a Network as needed without application. In the network, computers communicate through internal IP addresses. When the internal computer needs to communicate with the external internet, the device with the NAT Function (such as a router) converts an internal IP address to a valid IP address (that is, the requested IP address) for communication.

Update the public ip address of the Cisco router. First, confirm how your network is going. Here we will talk about the configuration based on our network: first, remove the default route no ip route 0.0.0.0 0.0.0.0 xxx. xxx. xxx. xxx adds the new default route www.2cto.com ip route 0.0.0.0 0.0.0.0 xxx. xxx. xxx. xxx then remove the ACL to overwrite the no ip nat inside source list 1 pool BJ.

One-to-one correspondence between the internal address and the egress address disadvantages: When the egress address resources are scarce, only a small number of hosts can be connected to the internet. 2. The internal address shares the egress address. The router uses the egress address and port number, as well as the external host
There are too many Qos information on the Cisco Router Traffic Control instance, but many of them are not practical. I have talked about a lot of theories. The following are the configurations on the routers of a subsidiary for your reference. In fact, as long as you understand the meaning of NBAR, CBWFQ, and WRED, traffic control can be configured as needed. Www.2cto.com Description: A subsidiary uses a 2
When we use Telnet to log on to the device, the user name and password are transmitted in clear text, in order to ensure the security of the data, we recommend the use of SSH login device. The following is the configuration of the Cisco router SSH:1. Configuring hostname and Domain-nameR1 (config) #hostname R1R1 (config) #ip domain-name frame.com2.

The port Mapping method enables access to specific port services from the Internet to the local area network internal machines. For example, the machine you are using is in a LAN connected to the Internet, all the services you open on the machine (such as FTP), by default, the outside world can not access. This is because your IP is the LAN internal IP, and the outside can access only the server you are connected to the IP, because the entire LAN on the Internet only a real IP address, and this
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
In recent years, the computer network, especially the Internet development is very rapid, ATM and IP over DWDM technology development so that the network transmission bandwidth quickly increased. While the development of network security and management technology is relatively lagging behind, although the voice of network security is high, but really fall to actually few. It is often believed that increasing the security mechanism of the enterprise network requires the addition of firewalls, aut
This is an article about the Cisco router IP address, which is very old and should be useful to everyone, so we have selected it from the vast network. Hope you don't sink it down. We will give you a satisfactory response on how to use the IP address of the Cisco router to obtain traffic. When using a
This article will discuss the importance of maintaining the password security of a Cisco router, explain the Cisco router mode, and show readers how to configure five passwords for a vro to protect network security.

There are many knowledge about Cisco routers. Here we mainly analyze the specific methods for Cisco router configuration. Have you ever encountered this problem in daily network management and maintenance: You have been forcibly rejected by a vro or vswitch, a former "friend", because you forgot your password, parameter resetting and information statistics are no
In CISCO router products, we usually need to restrict the access of general users during initial configuration. This is very important for Routers. By default, Our routers are an open system and the access control options are all disabled, any user can log on to the device to initiate further attacks, therefore, our network administrator needs to configure a password to restrict unauthorized users from acce
The market demand for Cisco routers is very high, so I studied the role of the Auxiliary port in Cisco router management. I would like to share with you here, I hope it will be useful to you.
