Step by step, you can quickly learn the comprehensive configuration of MSR router devices

With the development of China's route equipment, it also promotes the MSR router equipment market demand. Here we mainly introduce the comprehensive configuration of MSR router equipment, MSR router equipment is required for all enterprises to build their own internal LAN, while vrouters are used for network access and Internet routing, therefore, routers play a very important role in the normal operation of enterprise networks. However, for our network administrators, we may encounter the problem that the Router password is forgotten or tampered with by others, how can I restore the password to ensure security in the first time?

Remote telnet password forgotten: most enterprise network administrators use telnet to manage the MSR router device. If you forget this password, how can you recover it? We will do this step by step.

Step 1: When we set a password for the router and enable telnet remote management service, A user authentication prompt appears when any computer in the network accesses the vro through the telnet management IP address. You must enter the corresponding account name and password.

Step 2: Generally, the vrotelnet console Authentication and remote telnet AUTHENTICATION are separated. Therefore, even if telnet logon requires authentication, you may not need a password to directly connect to the console using the console line. Therefore, we can use the original Console line to connect the COM serial port of the computer and the console port of the MSR router device. Keep the default values for each attribute parameter.

Step 3: After successful connection, we usually find that you directly manage the MSR router through the console without a password, thus bypassing the telnet AUTHENTICATION.

Step 4: Go to the management interface and run the local-user command to change the password of the corresponding account to restore the password.

Summary -- the logon password for telnet and console control in MSR vro is set separately, so you can connect to the vrotelnet Management console through the console even if the logon password for telnet is forgotten.
