Manual binding entries
Address binding is a mapping between the IP address and the media access control (MAC) address of a client. The DHCP server
assigns the client an available IP address automatically and then creates an entry in the binding table. You can also manually
create an entry for a client. Manual bindings help to guarantee that a particular network device receives a particular IP address.
Consider manual bindings as single-host address pools. There is no limit to the number of manual bindings, but you can only
configure one manual binding per host. Manual binding entries do not display in the show ip dhcp binding output.
1. Create an address pool in DHCP mode.
pool name
2. Enter the client IP address in DHCP <POOL> mode.
host address
3. Enter the client hardware address in DHCP <POOL> mode.

With a fixed host configuration, also known as manual binding, you must configure a network pool with a matching subnet. The
static host-to-MAC address mapping pool inherits the network mask from the network pool with subnet configuration, which
includes the host’s address range.
In the following example, the pool host1, which is the fixed host mapping pool, inherits the subnet and other attributes from
the pool hostnetwork, which is the DHCP client IP address pool. There is no matching network pool for host2. Therefore,
the DHCP client with the MAC address 00:0c:29:aa:22:f4 does not obtain the correct parameters.
