When we want to perform permission rating management on a Cisco router or switch, it is often necessary to assign different levels of users a command that exceeds the default settings, such as show run, which is the most basic troubleshooting command.However, the command cannot be executed when your user level is at 0-14. You can assign permissions to these users using the following command:Privilege EXEC l
Network is inseparable from the password, as a network administrator to remember more than one router password, if the router password forgotten, we need to set up a router to restore the password.
Router password recovery has a common, that is, let the router start to skip the configuration file, direct startup, and finally change the password, and finally achieve the purpose of recovery password.
First, 2500 series Cisco router password recovery
It may take 30 seconds or more to connect a computer to a vswitch before the computer can communicate over the network. If you are waiting for a long time, 30 seconds of waiting will make you feel very long. Let's take a look at how to accelerate the port initialization process of the switch.Understanding the process of vswitch port InitializationWhen a device is connected to the port of a started switch, the swit
