create a pool

• Pool Name - Name for the DHCP Pool of Addresses
• Start IP Address - The start of the DHCP Pool of Addresses, the first Address pulled from the DHCP Server in a VLAN.
• Maximum Number of Users - Sets the total amount of users that can be pulled within the subnet range with the first IP being the starting IP Address.
• Default Gateway - Set this based on the VLANs Default Gateway Address being assigned.
• Subnet mask should be set to correct VLAN's subnet mask.
• Max Users should be set to the amount of hosts required for each VLAN. Once done, add the Pool to the rest of the DHCP Server Pool.

Commands

• Go within each VLAN interface and set the DHCP Server's IP Address so that each VLAN is pointed back towards it to get an address.

   `config t`
   interface vlan x - x being the VLAN's number. (i.e. 100,110,130,140).
   ip helper-address x.x.x.x - This will point the vlan towards the DHCP Server to receive an address from the corresponding pool.
  

Static to DHCP

• In each device on the network and change the Gateway from static to DHCP.
