How to set up dhcp binding in cisco?

Question

DHCP

Good afternoon, I need help from the hall.

Is available cisco 2800 with set of vlan'ov.
One of the vlans has a windows 2012 standard server with a Broadcom NetExtreme Gigabit Ethernet v15.4.0.17 network card,
but physically it's a Macintosh.

Thus, no matter what to prescribe

ip dhcp pool MAC_BINDINGS_VLAN34
host 192.168.34.250 255.255.255.0
client-identifier 01 685b.35b6.3764
default-router 192.168.34.254

or

ip dhcp pool MAC_BINDINGS_VLAN34
host 192.168.34.250 255.255.255.0
client identifier- 00 685b .35b6.3764
default-router 192.168.34.254

It does not bind IP to MAC.
It just ignores this setting and gives that poppy a random IP.

What do you advise to do?

Answer 1

1) Look at the poppy on command:
and nail it.
2) Refuse dhcp on cisco and transfer everyone to unix'ovy dhcp where there are no such problems.

Answer 2

1. It is this poppy that we nail.
2. Unfortunately, transferring dhcp from sisco is not an option.

Answer 3

I had a couple of times idiotic motherboards, in which the poppy address was different with each hardware power reset, as a result, I registered the poppy address through the operating system drivers and then it worked
