Again, here is the tip:
- create subnet pool
- let your test router acquire a DHCP address out of subnet ("ip address
dhcp" on the interface + may need to shut / no shut the interface) - if you
are not getting the address - something wrong with your setup
- go to the router which acts as DHCP server "show ip dhcp binding", right
down the client id
- create client id specific pool, using client ID as per previous step
- reboot your client router - it will get IP address as per the specific
pool
IOS does use client id, it does not use Microsoft style client id. See the
following link about how IOS compiles the client id

Hi, Phuong !
Try, This.
Ex'
Ip Address 192.168.1.12 255.255.255.0
hardware-address 1212.1212.1212
add prefix "01" for client-identifier then put your MAC Add.
ip dhcp pool R1
host 192.168.1.12 255.255.255.0
client-identifier 0112.1212.1212.12

From DocCD, client-identifier is only required by Microsoft DHCP client
:
client-identifier
To specify the unique identifier (in dotted hexadecimal notation) for a
Microsoft Dynamic Host Configuration Protocol (DHCP) client, use the
client-identifier DHCP pool configuration command. It is valid for manual
bindings only. To delete the client identifier, use the no form of this
command.

Try the exact same thing, but use client id instead. It will work then. You
may find it easiest to get unrestricted DHCP reservation happen first, and
then verify what server has (client IS or MAC):
router#show ip dhcp binding
IP address Client-ID/ Lease expiration
Type
Hardware address

HI group
I've just tested DCHP with manual binding. I want when a router come up, its
ethernet0 will be assign a fixed IP.
- First I've show the router interface for the Mac address (or configed the
mac address manually) R1#Sho int e0
Hardware is Lance, address is 1212.1212.1212 (bia 00e0.b055.9a29)
- Then I configure the DHCP,
ip dhcp pool R1
host 192.168.1.12 255.255.255.0
hardware-address 1212.1212.1212
both routers are in the same vlan.
But when I configure R1's E0:
ip address dhcp
The dhcp server can not recognize R1 and assign the ip address, it receive
the following messgase when I debug ip dhcp server packet and event
11:08:32: DHCPD: DHCPDISCOVER received from client
0063.6973.636f.2d31.3231.322e.3132.3132.2e31.3231.322d.4574.30 on interface
Ethernet0.
11:08:35: DHCPD: there is no address pool for 192.168.1.33.
So I decide to reconfigre the DHCP with previous complex client-id, and it
work well.
ip dhcp pool R1
host 192.168.1.12 255.255.255.0
client-identifier
0063.6973.636f.2d31.3231.322e.3132.3132.2e31.3231.322d.4574.30
But it isn't pretty way, anyone could do with the simple Mac address. Sorry
if my description is verbose
Thank you in advance
Phuong.
