How To Reserve An IP Address In CISCO DHCP Server

if you wanna  reserve an ip address for a certain client, for example a server in CISCO DHCP server follow these steps:

1- first you need to make a DHCP pool for this client alone.
2- find the mac address of the client "for example use (ipconfig / all) for windows and (ifconfig) for Linux" at the client, or you can use network scanners to find this information.
3- add 01 to the beginning of the mac address you got, for example:
if the mac address is 502c.e40e.fabf  add 01 to the beginning of the mac to be 0150.2ce4.0efa.bf.
01 indicates that it is an Ethernet client.
4- you can add optional features like the client name.
5- specify the lease period to be infinite.

Example:

ip dhcp pool amnetwrok
   host 192.168.10.1 255.255.0.0
   client-identifier  0150.2ce4.0efa.bf
   client-name AM-Client
   lease infinite
