For one device DHCP reservation doesn't work

I have these DHCP pools and reservations on my 871w router and the reservation for my wireless scale just doesn't work (orange color):

ip dhcp pool Glavni-pool

import all

network 10.100.200.0 255.255.255.0

default-router 10.100.200.10

dns-server 8.8.8.8

lease 0 2

!

ip dhcp pool SamsungTV

host 10.100.200.12 255.255.255.0

client-identifier 015c.a39d.3b8a.af

!

ip dhcp pool SamsungGS2

host 10.100.200.9 255.255.255.0

client-identifier 0120.6432.c1ed.7b

!

ip dhcp pool Acer3810TZ

host 10.100.200.8 255.255.255.0

client-identifier 0100.225f.93a4.26

!

ip dhcp pool WithingsWS30

host 10.100.200.7 255.255.255.0

client-identifier 0024.2407.fb5c

I tried entering client-identifier 0100.2424.07fb.5c, and hardware-address 0024.2407.fb5c but that didn't help either.

When i enter command debug ip dhcp server packet and try to connect my wireless cale I get:

DHCP server packet debugging is on.

And command show ip dhcp binding after that gives me:

10.100.200.13      0024.e407.fb5c          Mar 01 2002 04:48 PM    Automatic

Anyone have any ideas how can I reserve IP address for this device?

For one device DHCP reservation doesn't work

Hi,

looks like a typo in the fifth nibble:

10.100.200.7      0024.2407.fb5c               Infinite                                         Manual

10.100.200.13     0024.e407.fb5c               Mar 01 2002 04:48 PM    Automatic

Re: For one device DHCP reservation doesn't work

In one of my attempt I mistyped it... it is working now with hardware-address 0024.e407.fb5c

Thank you!
