Hi

This is obviously dependant an what switch you have and whether it supports the dhcp service. You will need to enable the dhcp service, then configure the pools.

conf t

!

service dhcp

!

ip dhcp pool VLAN1

network 192.168.1.0 255.255.255.0

default-router

dns-server

lease

!

ip dhcp pool VLAN2

network 192.168.2.0 255.255.255.0

default-router

dns-server

lease

!

ip dhcp pool VLAN3

network 192.168.3.0 255.255.255.0

default-router

dns-server

lease

!

This is just an basic example, and you may wish to add additional options. Please see the following url for detail config guide:

Hope this helps

ip dhcp pool VLAN

network X.X.X.0 255.255.255.0

default-router A.B.C.D

Where A.B.C.D is that VLAN interface ip address. If you want to exclude any ip address you can do it.

Don't forget options for DNS, WINS, IP Phones, etc.
