2621 obtain DHCP address from cable modem

[McCisco]

I want to hook this up

CABLE MODEM - 2621 - 2950 - PC

Problem - When I try to configure f0/0 to get DHCP address from cable modem I get the error. Could this version of code not support DHCP on a interface?

Thoughts?

.thats correct...you need a new code
...the below i am using in my 2600 series
...c2600-ik9o3s3-mz.123-19.bin
....it has additional functionality for cisco IOS firewall (that you need because it is/needs to serve as firewall/ids)
....and guess what?

perimeter_route(config-subif)#ip address ?
A.B.C.D IP address
dhcp IP Address negotiated via DHCP

..thats right, it supports it baby...
..how much flash and dram you sportin?
...have you accessed that site to pull the latests ios for your router?...
...you want atleast 12.3..something..and see the k9 in the code...

Try this...
router(config-if)#ip add ?

and post the output. Hey Dan---concerning the site---in the folders where the ios's are---at the bottom is a text file called description.txt---perhaps you could lend your expertise as to what the best ios may be, as I am no pro. It has one that includes IDS and IPSEC...IO would think that would be a real good one...

Latest up date.

~ I got one of the versions from the site. I was able to TFTP it to the router. The router rebooted and came up like expected. All the interfaces were there and I was able to set F0/0 to DHCP. I downloaded the "ik9o3s3" code. Manaully erased the flash, TFTP it to the router, when the router rebooted, it got the same "exceeded memory" error. I will move back to the version of code that worked. and all should be good. i have an exciting weekend planned of configuring the network, I will keep you posted over the weekend, thanks again for the help. I have learned more over the last few here, then i have in months from our egorant self-centered supposed engineers at work. That won't give you the time of day, if you not smarted than they are.

McCisco -

I have found that those who "won't give you the time of day unless you are smarter than them" usually do not know as much as they think they do. Study up - someday you'll probably surpass them.

You are exactly right helpdeskdan---in fact, in my experience it has always been out of fear---those who have been smug to me when I was trying to learn felt threatened, though I gave them no reason to feel like that. Thanks for that comment.
