Hello,

I am still a newbie and would like to know if anyone has an example of
how to

1.) How can I enable/set DHCP on a Cisco 831 VIA the CLI?
2.) How can I set the L2 interfaces so I can upload the SDM?
3.) How can I set the username, password, and community string so I can

access the router VIA a TFTP/SNMP host?

I lost the IOS (newbie mistake) and when I use tftpdnld to upload my
IOS, it doesn't let me access SDM. Any help would be appreciated!

THANK YOU in advance...

Daniel

So did you reinstall IOS?  If so, you need to add the SDM files in to the 
flash to make SDM work again.

Explains the whole process

When in enable mode

conf t
interface ethernet 0
ip address x.x.x.x 255.255.255.0

or

ip address dhcp

to set an address to start communication at the console.  After that you can 
telnet to the box and install SDM per the instruction above.
