Here's the scenario:
I replaced 2 core switches (3550 catalysts - 12G) on Wednesday. I have configured the VTP and added the VLANs to the database.
My core and ethernet switches can ping to the DHCP server. However, (most) of the end users are not receiving IP addresses. I have verified that the FastEthernet ports are correctly configured for the appropriate VLANs.
Thank you for your help!
