Cisco routers Command-Line Interface Configuration

When configuring a cisco router, the Command-Line Interface (CLI) is really the best way to configure a router, the reason for this is because the cisco CLI gives you the most flexibility and control over a router.

To use the CLI, just say ‘no’ to enter the Initial Configuration Dialog. After you say no, the router will

come back with messages stating the status of all the router interfaces.

Router: Would you like to enter the initial configuration dialog?

Say : [yes]: n

Would you like to terminate auto install? [yes]:return

Press RETURN to get started! And then you get all interface status as listed below

LINK-3-UPDOWN: Interface Ethernet0, changed state to up

LINK-3-UPDOWN: Interface Serial0, changed state to down

LINK-3-UPDOWN: Interface Serial1, changed state to down

LINEPROTO-5-UPDOWN: Line protocol on Interface Ethernet0, changed state to up

LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0, changed state to down

LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1, changed state to down

LINEPROTO-5-UPDOWN: Line protocol on Interface Ethernet0, changed state to down

LINK-5-CHANGED: Interface Serial0, changed state to administratively down

LINK-5-CHANGED: Interface Ethernet0, changed state to administratively down

LINK-5-CHANGED: Interface Serial1, changed state to administratively down

This is the current status of your router as the configuration are coming in the interface status will change from down to up depending on the input command.
