In-depth explanation of Cisco router default password

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 common WEB methods is to fill in an exciting IP address in the browser, for example, QX1680. In the browser address bar, enter the IP address 10.0.0.2. When the prompt bar appears, enter the User Name admin, the default password qxcommsupport of the Cisco router allows the Administrator to set the interface. This method is the most common and simple one.

The second method is to use TELNET to telnet the IP address, for example, early co-occurrence 642, telnet 192.168.1.1, and then enter the default password 1234 of the Cisco router to enter the English character interface.

The third method is to use the vendor's own configuration program to enter the configuration interface. For example, CyberLink 6307/6309 uses dslcom.exe in the optical disk with Cybrlink 6307/6309 kg. the default value is: Route IP Address: 1 92.161.1 Cisco router default password: stm, because this method is not as convenient as the first two methods, so the current low-end products are rarely used. Debugging of most products requires that the dual-stranded wires of the product be connected first, and then the IP address of the NIC of the local machine be set to the same network segment as that of the dual-stranded wires, if the default IP address or the default password of the Cisco router is changed, most of them can be reset to restore the default value. The most common and useful method is to keep holding down the reset key after power-off, and then power-on until it can be restored after a short period of time.
