Enabling static IP to MAC address mapping

Based on the client MAC address, you can statically configure the IP address to the MAC address in the DHCP server.

This configuration is useful when you want to have selected clients assigned with particular IP addresses from the server. Whenever a DHCP discover message is received from these clients, based on the static configuration, the IP address will be assigned with the other required parameters.

When configuring the static-mac-ip-mapping command, there must be at least two IP addresses available in the ip dhcp-server pool. One of the IP addresses will be excluded from the ip dhcp-server pool.

Enter global configuration mode.
```
device# configure terminal
```

Create a DHCP server pool.

device(config)# ip dhcp-server pool cabo

Enter the static-mac-ip-mapping command followed by the IP address and MAC address for mapping.
```
device(config-dhcp-cabo)# static-mac-ip-mapping 10.10.10.29 0010.9400.0005
```

The following example enables the static MAC address to IP address mapping.

device# configure terminal
device(config)# ip dhcp-server pool cabo
device(config-dhcp-cabo)# static-mac-ip-mapping 10.10.10.29 0010.9400.0005
