3500 switch client could not get IP from DHCP Server

[goranwong]

HI experts,

I am new to Cisco switch and I am copnfiguring the Cisco Catalyst 3500 series XL switch.

The problem is I have a Windows 2000 DHCP server on the lan connected to the switch, however, all client workstation that connected to that swtich could not get IP address from the DHCP server, but if the client workstation use static IP address, it can ping the DHCP server.

I read the switch config and there is on item states taht no ip directed-broadcast.

I suspected it causes the problem, does anyone know how to enable the broadcast? or there is other reason?

Thank you very much

I am running out of ideas on this one. I think the only thing left to do is to take a crossed-cable and connect the PC directly to the DHCP server. Does it get an IP address now? That will at least tell you whether the problem is something to do with the switch.

is there a command that can enbale the ip broadcast?

I think it will work out

hi,

Pl check whether your DHCP service is really running?

Pinging the device doesn't guarantee that service is also running

It is running well if I use the hub instead of the Cisco switch

I have experienced similar behavior with the Cat 3548XL switches in the past. The problem (that we had) was with the NIC drivers on the PCs/servers. It may help to upgrade the NIC drivers to the latest version provided by the NIC manufacturer not the microsoft drivers. As long as you are not going thru a router or layer 3 switch, then dhcp traffic should pass. You might check the port statistics for each port with static assigned addresses on the PCs. Also, make sure the switch ports and PCs/Servers are set to either autoneg or static assigned speed/duplex.

Hope this will help.
