DHCP issue through Cisco 3550 issue

[mose@CP]

Here is the scenerio.

1. the PXE server is found, and i choose my OS-Install option

2. the server downloads boot data to my client

3. the setup environment starts (blue/green bkgrnd)

4. an error message dialog is displayed, "WdsClient: An error occurred while obtaining an IP address from the DHCP server. Please check to ensure that there is an operational DHCP server on this network segment."

 

I know it is an issue with the switch, I just do not know how to fix it.

The WDS server goes through 2 other switches to hit the last switch. If I remove the third switch it will load the image fine. I hook up the Cisco 3550 in order to get more connections and it doesn't work. The first two switches are also Cisco 3550. The setting look to be identical.

 

One post I saw said to make sure STP is enabled and it is. Any suggestions besides using an 8-port Netgear switch. I am not very Cisco savy yet.

perhaps you have to configure IP Helpers on the cisco switch to point to the DHCP server

I am a cisco noob. Where do I go using the network assistant to check that?

I will tackle the Cisco switch another time. I found an old HP 24 port hub that is doing the trick just fine. Thanks for the help

It is working. I am not sure if it was a Port Fast issue or VLAN issue, due to the fact that both changes were made before I tested.
