A new 3750-24TS switch arrived in our office these days. I want to remove our DHCP server from the Win-based win2000 server onto this new switch. When i issue some IOS command such like "ip dhcp", "dhcp pool",,,etc, one client's NIC directly connected to 3750 can get a dynamic IP (verified from 3750's output with "show dhcp binding")during pxe boot. But, this new IP can't communicate with Tftp server( with manually permenent fixed IP, and directly connect to this 3750 switch port), so the pxe boot procedure hung at "PXE-E32, TFTP open timeout".Mean while I cannot ping this unique ip of the NIC.
Apart from above small amount newly issued IOS command, I believe near almost every other setting still remain in default state.
Again, we have only one network like 192.168.1.0 255.255.255.0
can you tell me how can i deploy this IOS dhcp server and insure those DHCP client obtain from this server can "talk" correctly?
thanks in advance.
Please check the IP address setting on your PXE server and compare to the DHCP pool on your switch. Also check that the ports are in the correct VLAN (same VLAN if you use only one subnet, if multiple subnets are used multiple L3 VLANs are needed). Check the status of the configured VLAN is it in up and up state (show ip interface brief), if not please check that the VLAN is properly defined in the VLAN database, show vlan brief (you can define VLAN on VTP server or transparent devices).

Please rate me if I helped.
