Dymamic IP what IOS version?

[r-zaluski]

I am setting up a cable modem and a Cisco 2600 series router.

Anyone know the IOS version I will need?

Thanks

I understand you are looking for the "ip address dhcp" command under the ethernet interface, introduced in 12.1(2)T , any image after 12.1(2)T should be fine.

Thanks, Mak.
