Hi Dhaval,
It should work in both the scenarios. In first scenario on which vlan you have configured this ip address and also on which vlan you have connected your client.
Do something like this taking an example of vlan 10
interface vlan 10
ip address 172.168.1.100 255.255.255.0
interface fa0/10
switchport mode access
switchport access vlan 10
Connect you client on this interface and it should be able to get an ip adfdress frm your DHCP pool.

Hi Dhavel,
Try changing your network statement to
network 172.168.1.0 255.255.255.0
or
network 172.168.1.0/24
Also you can exclude your default-router address from the DHCP pool list with command
"ip dhcp excluded-address 173.168.1.100" to be issued on global config mode.
Also can you confirm which vlan this subnet belongs to and you have connected you clients on same vlan?

Dhaval,
You need to have a normal subnet mask and not the inverse wild card mask when defining the network range
Also it is always wise to exclude the ip address configured on the 3550 if any
If you have any access-lists make sure it allows UDP ports 67 & 68
HTH, rate if it does

Hi all,
Thanks for takin interest,
i did same
i exclude the address as well given the correct sub-net mask. and i don have any access-list between.
my scenario is
Laptop (Client)----3500 (DHCP Server)
i am confuse with this scenarion, i don have hand on with layer-3 devices. is this connection looks good.? i also tried as,
Client---L-2-Switch-----3550 (DHCP Server)
where 3550 has one port as layer-3 (no switchport & also assigned ip-address)
still it dosent work.
thanks
