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)
