network will be fatal. Therefore, to improve security, the Cisco router sets password management for the Auxiliary port. Therefore, it is recommended that the network administrator do not use the same password as other passwords in password settings. Otherwise, the security of the router is reduced. In short, the Auxiliary port plays an important role in vro management. Generally, the Console port is used only when the vro is configured. In the proce

"hard" operations on network devices. The security factor is high, but the obtained information is not accurate. For example, if the IP address of a server has been changed, we can think that the server is not connected to the network because the original IP address cannot be found on the switch. The system administrator first checks the IP address information on the server, and then finds out which port of the switch the IP address is located on. The information obtained by this method is very
