DHCP Server has been supported on the 2500 since 12.0(1)T.

Hope this helps,

Re: 2500 series IOS support DHCP server ??

Dont know if you needed DHCP on the lan side or to lease IP addresses on to client dialing into the router via a modem....Like posted in the other post, DHCP is supported in 12.0 version of IOS. You should be looking for a command like...

config t

ip dhcp pool test

network 10.0.0.0 /8

default-router 10.0.0.1

lease 3

Now, you can also lease ip addresses to clients dialing via modem, by creating a local pool, as follows.

ip local pool test

int async 3

peer default ip address pool test

hope either of them helps!

Hi, I have IOS 12.0(25) version.

when I try to

config t

ip dhcp pool test

it said invalid input dectect

do you think my ios is not support ?

thanks for your time again.

Re: 2500 series IOS support DHCP server ??

You are not probably having the right feature set of IOS. Paste an output of "show version" for further analysis.

Re: 2500 series IOS support DHCP server ??

As I indicated in my first email, you need at a minimum the 12.0T train. It is not supported in 12.0. Upgrade to 12.1 or 12.2 and it should be fine.

Hope this helps,

Re: 2500 series IOS support DHCP server ??

You certainly can as long as you have 10M of DRAM and 16M of Flash for the IP/IP Plus feature set. I would suggest you go ro 12.2(23) since it is the latest GD.

Hope this helps,
