router(config)#ip dhcp pool room12

router(dhcp-config)#network 172.16.1.0 255.255.255.0

router(dhcp-config)#exit

router(config-if)#ip dhcp excluded-address 172.16.1.1 172.16.1.10

or based on static mapping from MAC

ip dhcp pool room12

host 1.1.1.1

hardware-address aaaa.aaaa.aaaa

The ip dhcp excluded-address command configures the router to exclude 172.16.1.1 through 172.16.1.10 when assigning addresses to clients. The ip dhcp excluded-address command may be used to reserve addresses that are statically assigned to key hosts.

please rate

You are not getting my question. I have configurd Pool, exclusiona and other setting.

My requirement is for MAC-00.0E.0A should get a fix IP address from Pool. I mean I am looking for IP address reservation based on MAC.

3. ip dhcp pool pool-name

4. host address [mask | /prefix-length]

5. client-identifier unique-identifier

6. hardware-address hardware-address type

7. client-name name
