Reserver IP address via DHCP

[jorgeacat]

I defined a pool of DHCP on IOS software, I want to reserve a IP address to host, I made it, only that doesn't assigned the IP address that I defined in the pool

Help? How I can to do it?

Example

ip dhcp pool guestimport all

network 172.23.12.0 255.255.255.0

default-router 172.23.12.254

address 172.23.12.231 hardware-address 0100.14c2.c6ec.42

Do not use hardware-address.

Use client-identifier, chek "show dhcp server lease", you have to add one extra byte to the mac.

Jorge,

First you have to create an IP dhcp pool for your clients, then for a fixed IP address create another IP dhcp pool.

Example, if your MAC is 12.34.12.34.12.34

ip dhcp pool Client1

host 172.23.12.200 255.255.255.0

client-identifier 0112.3412.3412.34

Release the IP and renew IP address and IP address 172.23.12.200 will be assign it.

Hope this helps.
