Privilege Mode

• Router# it is the administrating mode, we can check whether the settings and configurations made have been implemented or not.

Eg-• “Router # Show ip interface brief ”. If it is new router all the

interfaces are by default shut down, so the message will be, “ administratively down, line protocol is down.”

Configuring a Router’s Name

• A router should be given a unique name as one of the first configuration tasks.

• This task is accomplished in global configuration mode using the following commands:

• Router(config)#hostname TokyoTokyo(config)#

• As soon as the Enter key is pressed, the prompt changes from the default host name (Router) to the newly configured host name (which is Tokyo in the example above).
