Have a Cisco 3750 with a bunch of VLAN's configured for our vmware esx environment. If I plug in a client (esx ot windows) and make a DHCP request, the client never get a address. Have put a sniffer between host and swicth and reguests is seen but when sniffer is between the switch and the next one no dhcp request is seen.
It works fine when in switchport access mode but never in switchport trunk mode.
Is there anything to configure on the 3750 to allow dhcp requests to pass through? Thanks alot. Marten
