Binding MAC to IP using client-identifier

md_ani · ‎06-05-2009

Hi,

I have 10 PCs on the network to which I want to allocate fix/specific IP from DHCP server configured on my 3825 Router. Currently I am using IP Pool & "client-identifier". Problem is that, for every Host/IP I need to create separate Pool. Is there any procedure via which I need not to create separate pool for separate IPs/Hosts. Below is the snap of Configs for ref.

************************

ip dhcp pool fixip-1

host 192.18.144.104 255.255.254.0

client-identifier 0100.2170.7b7c.ca

lease 7

!

ip dhcp pool fixip-2

host 192.18.144.105 255.255.254.0

client-identifier 0100.1b24.6190.ab

lease 7

!

ip dhcp pool fixip-3

host 192.18.144.106 255.255.254.0

client-identifier 0100.219b.e562.fd

lease 7

!

ip dhcp pool fixip-4

host 192.18.144.107 255.255.254.0

client-identifier 0100.0e7f.a421.af

lease 7

!

ip dhcp pool fixip-5

host 192.18.144.108 255.255.254.0

client-identifier 0100.23ae.015f.23

lease 7

There is no alternative to your config above.

DHCP option 82 will do the trick....but then you need a dedicated DHCP server.
