Setting up DHCP snooping?

[abrrymnvette]

I'm going to setup DHCP snooping and had a question about it.

My DHCP server is connected to port 1 on a switch stack. I set that port as "ip dhcp snooping trust"

The trunk link that connects my switches together also gets set as "ip dhcp snooping trust"

Do I have to do anything on my switch stack at the other end of the trunk line? The VLAN's already have the ip-helper address configured.

DHCP server ----------Switch Stack 1<><><><>Switch Stack2---------DHCP Client           

Basically, I think this is all I need to do:

Switch1(config)#ip dhcp snooping

Switch1(config)#ip dhcp snooping vlan 10

Change to the trunk interface:

Switch1(config-if)#ip dhcp snooping trust

Change to the interface connected to my DHCP Windows server:

Switch1(config-if)#ip dhcp snooping trust

Change to Switch2 and configure the trunk port that connects to Switch1 as trusted?

Switch2(config-if)#ip dhcp snooping trust

just make sure is snooping enabled on all

switches between dhcp server and clients

Hi,

Just to add to what has been said, you also need the following commands on all the switches:

ip dhcp snooping

ip dhcp snooping vlan 10
