Lab 3.2: DHCP Server in Packet Tracer - squatchulator/Tech-Journal GitHub Wiki

How to create a pool

  • First open the server you want to configure. Navigate to Services->DHCP
  • Type in the information for each subnet (each subnet gets its own pool)

Working with the serverPool pool

  • This is the default pool and cannot be deleted. It can be edited and used though.
  • In this lab, we used this as the management vlan (VLAN 1)

Assigning IP Helper addresses

  • On a multi-layer switch, enter config mode.
  • Select the interface with interface vlan <id>
  • Now type ip helper-address <dhcp-ip-address>
  • Repeat for each VLAN you are using.

Issues

  • One of the core issues that I ran into was not having VLAN 1 active. I did not realize that this VLAN doesn't automatically go live when you configure it, so I spent a long time going down the wrong paths trying to diagnose what was wrong. I finally tried enabling it and I was able to ping between systems. In the future, I am going to make it a point to enable VLAN 1 on every switch just to rule that out as an option.
