Server Pools

Using GUI

  • The default server pool is "serverPool" and it cannot be removed.
    • For this lab, we will use serverPool as our Management VLAN.
  • You have to create a pool for each VLAN on the network.
  • Leave TFTP to 0.0.0.0, same with DNS for now.
  • Everything else must be filled in correctly or you will have errors later on.

IP Helper Addresses

Using CLI

  • DHCP requests are broadcasts and cannot cross a router without help from a IP helper address. We need to tell the VLANs where to forward the DHCP requests.
  • Use ip helper-address <ip-address of DHCP server> to set this once you are in the VLAN interface configuration.
