DHCP Server in PT Lab

Purpose:

In this lab, we build onto our Lab 2-1 Network Environment by adding and configuring a DHCP Server to dynamically assign IP addresses to host systems on different subnets/VLANs.

Materials:

• Cisco Packet Tracer
• Week 2 Lab or Packet Tracer Starter File

Objective:

The completed lab environment should look similar to below:

Note: All workstation devices should be able to receive an IP via the DHCP Server as well as ping each other and devices on different subnets.

Additionally, here is my completed DHCP Server Pool Setup:

How to Create Pools on a Packet Tracer DHCP Server

In order to create New Pools on a Packet Tracer DHCP Server:

• Select your DHCP Server > Select the Services Tab > Select DHCP > In the DHCP Server Manager Menu --> Enter the necessary information to create a your new DHCP Pool (i.e. Pool Name, Default Gateway, DNS Server (if available), Start IP, Subnet Mask, Max Number of Users) > Finally, select Add to create your New Pool.

Working with ServerPool

ServerPool is the default DHCP pool assigned to the local network of a given Packet Tracer DHCP Server. In order to modify the ServerPool configuration: Select your DHCP Server > Select the Services Tab > Select DHCP > Under the DHCP Server Manager Menu --> Select ServerPool and modify the necessary settings for your environment configuration (ex. Setting Start IP Address, Subnet Mask, and Max Number of Users). > Click Save to apply the new Pool Settings.

Assigning IP Helper Address

IP Helper Addresses (DHCP Relay Agent) are used on routers and L3 Switches to forward DHCP request from one network to a DHCP Server on another network. In this lab, we use IP Helper Addresses on the East-Core-Switch to forward DHCP requests from the Student, Faculty and Lab VLANs to the

In order to configure this, I used the following commands in the Cisco Switch Terminal:

• ena > conf t > int vlan <vlan-number-here> > ip helper address <DHCP-Server-IP>

Note: This command was repeated for each VLAN on the network (with the exception of VLAN 1 as the DHCP Server already resides on this network).
