Cisco 1721 Config fastethernet

OK, I am new to the Cisco world not to mention the CLI. What I need is the command sequence to set the fastethernet IP and subnet.

I don't even know how to get into config mode so go through it step by step.. I know it can't be that hard.

Background info:

I was working in the web interface and removed the IP's from both NIC's and now I can't get in. However, I am able to log on to the CLI. If I can get the fastethernet nic to have an IP, I'll be able to get into a familiar interface again.

telnet into the router

type in the following:

enable         ---->enter priviledge mode
conf t          ----->enter configuration terminal
interface fastethernet 0            ----->select the interface
ip address 10.12.21.22 255.255.255.255  ---------->set the ip address and subnet using real values here
no shutdown  --------->enable changes
exit
exit

This should get you going

BTW each line above is followed by the enter key so you would type in enable <enter> , conf t <enter>, etc...

Here are the commands (abbreviations that work and full commands)

From the router prompt enter

en (enable)

(enter Password)

conf t (configure terminal)

int f0/0  (interface Fastethernet 0/0 or whatever port you're configuring)
 description (optional, but nice)
 ip address 192.168.1.1  255.255.255.0  (for a class C address)
 no shutdown

<Cntl Z>

That's all you need for the interface. Now if your configuring routing (RIP, EIGRP, OSPF) there's more to it.

When you don't know what to type, or how, type ?

If you know the beginning of the command, type the first letter or two and then ? to get a list of commands that begin with those letters.  When you've typed enough to be unique, you can hit the tab to have the command auto completed.

OK, I'm in! Thank you all for the great input. I know I have a ways to go in learing this router. I'll be setting up a VPN next to authenticate agains a  RADIUS server (win2k3) but that is another question!
