static ip's in dhcp

[Wizumwalt]

I'm trying to get a switch on my network to get a specific ip, but even though I put the mac address in my /etc/dhcp/dhcpd.conf file as such ...

subnet 192.168.2.0 netmask 255.255.255.0 {
default-lease-time 86400;
max-lease-time 86400;

option routers 192.168.2.1;
option broadcast-address 192.168.2.255;
option subnet-mask 255.255.255.0;
option domain-name-servers aaa.bbb.ccc.ddd;
option domain-name "mydomain.us";

next-server 192.168.2.10;

group {
filename "pxelinux.0";

host mswitch { # my switch
hardware ethernet 00:60:dd:47:b7:d8;
fixed-address 192.168.2.5;
}
...

My switch still won't get the ip of 2.5. Here's the output of my messages. As you can see, my switch gets 2.2, but not the static ip of 2.5 and I don't understand why since it's not being used, it was offered (DHCPOFFER), and 2.2's lease seems to be unavailble (which I know it's not, no one has it). Or maybe I'm just not understanding the output correctly. I'm using isc's dhcp 3.0.3.

Any help much appreciated.

The server offered the switch 2.5, but the switch requested 2.2 in response. The server denied the request for 2.2.

Check the settings on your switch. It's acting like it cached 2.2 as its current DHCP lease and is just trying to renew it. If it was a workstation, you'd simply do a release/renew. You may have to set it to static at 2.5 and then power cycle it, then set it to dynamic. That might clear out that 2.2 address.
