Dear All,
I want to configure my Cisco Switch 3560 as DHCP server so that my users in different vlans (configured) can assign IPs automatically,
I am using this configuration,
ip dhcp pool Marketing
network 192.168.2.0 255.255.255.0
default-router 192.168.2.1
dns-server 192.168.1.17
what else i need to configure on my layer 3 switch to work properly..
In this case, when i connect a PC to a port assigned in Vlan 2, its not getting Ip address automatically,,
Please write Sample configuration...
Regards,
Junaid

network 192.168.2.0 255.255.255.0
default-router 192.168.2.1

!
service dhcp
!
ip routing
!
int vla 2
ip address 192.168.2.1 255.255.255.0

Dear Toshi,
I applied your configuration but it is not working,
Please check my configuration,
ip subnet-zero
ip routing
ip dhcp excluded-address 192.168.2.1
ip dhcp excluded-address 192.168.2.1 192.168.2.20
ip dhcp pool D_MKT
network 192.168.2.0 255.255.255.0
default-router 192.168.2.1
dns-server 192.168.1.17
domain-name 192.168.1.17
lease 8
ip dhcp-server 192.168.2.1
vlan 2
name MKT
interface FastEthernet0/8
switchport access vlan 2
switchport mode access
interface Vlan2
ip address 192.168.2.1 255.255.255.0
ip access-group 110 out
ip classless
access-list 110 permit ip 192.168.1.0 0.0.0.255 any
I applied ACL to permit different vlan users to get access on servers vlans...
Please HELP!

I applied ACL to permit different vlan users to get access on servers vlans... < --- And there's an explicit DENY ANY ANY at the end of the line.

Junaid ,
Let's modify things.
access-list 110 permit ip 192.168.1.0 0.0.0.255 any
access-list 110 permit udp any eq bootpc any
access-list 110 permit udp any eq bootps any
HTH,

Dear Toshi,
Congratss!!
previous configuration started working,
Actually, the machine which i was using for testing, (its DHCP service was blocked),,
When i tried it with another Computer, it is getting Ip address and other information,
THANKS AGAIN..

Junaid,
You're right. I got confused because the router generating traffic would not be blocked by outbound ACL.
Good job,
Toshi
