Hello,
I am really new in this world , I have already read some CCNA BOOKS , but I would like to archive , does NOT work.
I try to create a table with MAC addresses that will distribute a IP ADDRESS.
My DHCP network is OK , but when I add
ARP AAAA.BBBB.CCCC 192.168.1.10 ARPA
it does not work.
Can one of yo guide me ?
Thank you in advance for your help
Best Regards,
Didier

Hello,
I was a little bit to fast when I write this in the forum , but I presume you knew what I mean , I mean this :
ARP 192.168.1.10 AAAA.BBBB.CCCC ARPA
I have read on some other forums that I have to add a 1 in front of the MAC address , but this does not change anything.
I have tried to put the IP address in the range of my DHCP POOL and OUT of the RANGE , no change
Is their something that I have to add in my config ?
Thank you again for your help
Best Regards,
Didier.

Hello,
Can someone tell me what I do wrong ?
I have a NAS SERVER , but instead putting a FIX IP in the NAS , I would like to tell DHCP to use IP 192.168.1.10 when he receive its MAC ADDRESS.
How can I do / solve this ?
Thank You in advance for your help.
Best Regards,
Didier.

Hi,
You have to create a new pool for this client and if it's a linux machine then
use host command to give the ip address and hardware-address "mac address of client" or client-id "id of machine" where id= modified mac as you said above.

Hello,
I am still struggling with this , I have try many things :
Including the FIX IP in the EXCLUDE RAGE
ip dhcp excluded-address 192.168.100.1 192.168.100.99
or changing the IP EXCLUDE RANGE from 192.168.100.99 to 192.168.100.9 , so the FIX IP's are NOT IN the EXCLUDED RANGE , but still it does not work.
The 2 products that I am struggling with are :
A QNAP NAS SERVER (I THINK IT IS RUNNING ON LINUX)
And my MAC BOOK PRO
Both of them receive a IP from the DHCP SERVER and work well , but NOT with the IP that I would like to give them.
MAC BOOK PRO = 192.168.100.20 is 192.168.100.100
QNAP NAS SERVER = 192.168.100.66 is 192.168.100.101
Here bellow the script and DHCP and ARP information :

You are excluding from 100.1 to 100.99 which includes your .66 and .20 so just exclude 100.1 and second change your hardware-address for FIX IP

Hello,
Just to let you know that the problem is solved
In case someone has the same problem I will explain what I did :
First , like CADETALAIN recommended me I have change the DHCP RANGE.
When this was done , nothing was changed I still have a IP from my DHCP SERVER , but NOT the one that I ask for.
After reading and GOOGLELING , I found some other interesting information :
I changed from HARDWARE-ADDRESS to CLIENT-IDENTIFIER , this did not help yet , but when I moved the DHCP SERVER :
ip dhcp pool internal
network 192.168.100.0 255.255.255.0
dns-server 192.168.100.1
default-router 192.168.100.1
From TOP to bellow the FIX-IP , BOTH MAC / IP where working OK.
Is this a BUG in c1841-spservicesk9-mz.124-15.T12.bin ?
Here bellow a copy of the working MAC to FIX-IP :
Best Regards and thanks to ALL OF YOU for your HELP,
Didier.
