Problem with dhcp

THA_DOC

I am working on lab in which I am having some problems with dhcp leasing ip address. I setup vlans on one of my switches but it seems my vlans are blocking packets.
Can explain what wrong?

Router cfg:

hostname Router
ip ssh version 1
interface FastEthernet0/0
 no ip address
 duplex auto
 speed auto
!
interface FastEthernet0/0.1
 encapsulation dot1Q 1 native
 ip address 192.168.1.1 255.255.255.0

interface FastEthernet0/0.50
 encapsulation dot1Q 50

line con 0
line vty 0 4
 login

end

Here on Switch0 is where my problems are occuring: 
hostname Switch0

interface Vlan1

!
interface Vlan50
no ip address

interface Vlan99

!
line con 0
!
line vty 0 4

line vty 5 15

end

Can explain what I am doing wrong. I am unable to post diagram of the entire network.

Have you got DHCP Snooping turned on anywhere?

No I don't have DHCP snooping turned on. Should try snooping on for each vlan on both switches?

keenon

did you take notice of

interface FastEthernet0/0.150
encapsulation dot1Q 150
ip address 192.168.150.1 255.255.255.0

and

interface FastEthernet0/1
switchport trunk allowed vlan 1-99
switchport mode trunk

something is missing

THA_DOC

Let me clarify something. This just lab i was working in Packet Tracer. Dhcp snooping is not available in Packet Tracer on the switch or router. Dhcp olnly has two function listed that is pool and exclude.

On the 2nd switch where I have not setup vlans the PC connected to it is receiving ip address from router via Dhcp.

Did you see kennon's post? You have DHCP set up for VLAN 150 but then only allow 1-99 through the trunk. You also do not seem to have any switchports set to access 150.

If thats an L2 switch, these commands wont work. If your using a L3 switch, you need the "ip routing" command and int fa0/1 needs to have an ip address/"no switchport" and use a routing protocol to route back to the router.

interface Vlan1
interface Vlan50
interface Vlan99

Im guessing your using a L2 switch and want to have the router handle DHCP since your using sub interfaces on the router and trunking to the switch.
Just add these commands to the switch. And verify with "show vlan brief" command. Or use the 3560 and use it as a router. This is a CCNP level topic. I would drop the vlan pruning also "switchport trunk allowed vlan 1-99".

Vlan1
Vlan50
Vlan99

You right I am using L2 switch and don't work. Should I still know how to configure Dhcp at CCNA regardless if covered under CCNA. But will hurt myself stressing something under the CCNA, I'll learn afterwards.

Thanks

Yes you should know DHCP at the CCNA Level. You should make your DHCP pool match the VLAn so its easy to find in the Routers config. Use the commands below and just change the ip address to match the vlan id. For example "vlan 55= Dhcp pool 55"

Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#ip dhcp excluded-address 192.168.55.1 192.168.55.10
Router(config)#ip dhcp pool 55-DATA
Router(dhcp-config)#network 192.168.55.0 255.255.255.0
Router(dhcp-config)#default-router 192.168.55.1
Router(dhcp-config)#dns-server 8.8.8.8 4.2.2.2
Router(dhcp-config)#exit
