Mapping MAC and IP address

[intertouch]

Hi, I am using the Cisco 3825 router as the DHCP server. How should I configure the router to ensure certain MAC addresses of the PCs always get the same ip address via DHCP?

Hi Friend,

You can got for static DHCP binding while configuring your router as DHCP server but remember you have to configure seperate DHCP pools for each single host for static binding.

service dhcp

!

ip dhcp pool host1

host 192.168.1.2 255.255.255.0

client-identifier xxxx.xxxx.xxxx ! put your MAC address here

default-router 192.168.1.1

You will need to configure one DHCP pool per client.

Specify the MAC address of each host and the associated IP within each pool...

This link will give you all details about DHCP related commands

Hi

You can use "manual binding", but keep in mind that

only configure one manual binding per host pool,, lot of work to do.

ip dhcp pool Mars

host ip addess

hardware-address MAC type

Thanks
