Problems with Interface Enternet command with 1700 & 2600 router

[don28]

Could I please have someone help me. For some reason or another every time I try to configure the Ethernet port I always get the following error.

interface ethernet 0
^
% Invalid input detected at '^' marker.

I’ve tried using all of the Cisco router commands of (Interface e0, Interface Ethernet 0, Internet Ethernet 0/0) and all come up with the following error.

% Invalid input detected at '^' marker.

Please note that this has happened on my Cisco 1700 and Cisco 2600 routers. Can someone please help. I’m trying the configure my router to permit the DHCP config for my home network training.

ALSO, I’m having problems with saving the “copy run start” command to my 1700 Cisco router and I have used the following command:

O/R 0x2142 and confreg 0x2142

Did you forget to "config terminal" first?

I think that the ox2142 tells the router to skip the stored config.

Try issuing this command.

Router(config)# config-register 0x2102

That should make the router boot from the written config.

I always get those backwards.

As far as the interface commands

when you get on router.

enable
show run
(look for how the interfaces are referenced in the show run.)

conf t
interface ~~~whatever you see in the show run~~~~
ex. interface Fast Ethernet 0/0

What exact models?
router>en
router#sh ver
That will give all the interfaces. If it is Ethernet, then...
router#conf t
router(config)#int e0
Or if it is like a 1720/1721, then it will have a fast ethernet interface, in which case...
router(config)#int fa0
If it is a 2610/2611, then...
router(config)#int e0/0
or the 2611
router(config)#int e0/0 or
router(config)#int e0/1
If a 2620/2621, then...
router(config)#int fa0/0 or
router(config)#int fa0/1
Also, are you trying to get to the native interfaces, or a WIC that you installed? If it is a WIC, for example a WIC-1ENET in a 1720, then if you do not see it in
router#sh ver
then the IOS needs to be upgraded. If you need help, post a
router>en
router#sh ver
and I or anyone else can show you how to get to the interface configuration.
