Cisco Router set up DHCP static mapping

Set up static mapping for device that requires permanent IP address rather than IP assign by DHCP server (for example for printer)

Requirements:

Static IP for printer

MAC address of the printer

IP DHCP pool: 172.19.142.0 255.255.255.0

Excluded IP: 172.19.142.0 172.19.142.99 and 172.19.142.200 172.19.142.255 (our excluded IPs)

Static IP (printer): 172.19.142.211

Set up excluded addresses:

(Static IP needs to be one of excluded IPs)

#ip dhcp excluded-address 172.19.142.0 172.19.142.99

#ip dhcp excluded-address 172.19.142.200 172.19.142.255

Set up DHCP pool:

#ip dhcp pool LAN_POOL

import all

network 172.19.142.0 255.255.255.0

domain-name cisco.local

default-router 172.19.142.254

dns-server 172.19.142.17 172.19.140.16

lease 0 2

Set up Static IP Mapping:

#ip dhcp pool STATIC

host 172.19.142.211 255.255.255.0 (printers IP)

hardware-address d485.6440.b314 (printers MAC address)

domain-name cisco.local

default-router 172.19.142.254

dns-server 172.19.142.17 172.19.140.16

Clear DHCP address from router database:

#sh ip dhcp binding (to see DHCP database)

#clear ip dhcp binding 1.1.1.1 (This will clear IP address from router database, but the device will still respond on old IP. To assign new IP: reboot of the device or clear old IP with ipconfig /renew)
