- 5. USER MODE • Router> is the user mode, I.e. the default prompt. It means that when ever a router boots successfully it lands into the user mode. Router cannot be configured from this mode, but it is used for monitoring purpose. • Router> enable • Router # MNS Protected©2013 | Ver 1.1 5
- 6. 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.” MNS Protected©2013 | Ver 1.1 6
- 7. Global Configuration Mode • As the name indicates, it is a global configuration mode I.e. we can configure routing and any interface from this mode, just by entering into the interface mode. • Router# Configure Terminal • Router (Config)# MNS Protected©2013 | Ver 1.1 7

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 Tokyo Tokyo(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).

Message Of The Day (MOTD) • A message-of-the-day (MOTD) banner can be displayed on all connected terminals. • Enter global configuration mode by using the command Router# configure terminal Enter the command Router(Config)#banner motd $The message of the day goes here$ • Save changes by issuing the command copy run start MNS Protected©2013 | Ver 1.1 13
- 14. The “Clock” Command • The clock command is used to set the clock of Router. Syntax • Router# clock set hh:mm:ss Day of week Month Year E.g. • Router#clock set 16:35:00 20 Oct 2013 • Note* This is the only configuration which can be done from privilege mode, every other configuration should be done at global configuration mode only.

- 15. Show commands in privilege mode • Router# show clock • show interface(interface name e.g. e0) • Show history • Show running-config • Show startup-config To save configuration from Ram to Nvram • Router#Copy Running-config Startup-config (or) Write MNS Protected©2013 | Ver 1.1 15
