DHCP PROBLEM ON CAT 3750

[elop]

Hi.

I am trying to configure my CATALYST 3750 as a DHCP Server.

I need to configure a STATIC DHCP binding between a MAC and a IP address.

I had configure the follow but the PC (winXP)does not get the address from the switch.

With a sniffer I see the DHCP request but there is No reply.

The configuration is:

service dhcp

ip dhcp pool test

host 1.x.1.x.0.0.0

client-identifier 0002.8a96.9fba

default-router 1.1.1.254

what am I missing???

THANKs

Hi,

Have you configured a VLAN (routed) interface on the switch with a 1.1.1.x address ?

Hello,

Microsoft Windows clients require a slight change to the client-identifier, which is prepending a '01' for Ethernet. You might want to try the following:

service dhcp

ip dhcp pool test

host 1.1.1.5 255.0.0.0

-->client-identifier 0100.028a.969f.ba

default-router 1.1.1.254

used debug ip dhcp, to see if your cisco switch heard the dhcp request.

Yes,

The switch receives the DHCP request, it can be seen using the debug DHCP and also using a sniffer.

I had try it, did not help.

Any other idea?

Yes.

interface vlan 1 has the ip address of 1.1.1.254 /8

enabled.

Hello,

can you post the full configuration of the switch, and indicate on which port the client is connected to which the static binding has to be go ?

Hi.

See the attached file.

The DHCP client is connected to interface fastethernet 1/0/1

Thanks for your help.

[elop]

YES, interface vlan 1 is enabled.
