Reference Guide

1. Enable DHCP server-assigned dynamic addresses on an interface in DHCP <POOL> mode.
ip dhcp server
2. Create an IP address pool and enter the pool name in DHCP mode.
pool name
3. Enter the NetBIOS WINS name servers in order of preference that are available to DHCP clients in DHCP <POOL> mode.
netbios-name-server ip-address
4. Enter the keyword Hybrid as the NetBIOS node type in DHCP <POOL> mode.
netbios-node-type type
Configure NetBIOS WINS address resolution
OS10(config)# ip dhcp server
OS10(conf-dhcp)# pool Dell
OS10(conf-dhcp-Dell)# netbios-name-server 192.168.10.5
OS10(conf-dhcp-Dell)# netbios-node-type Hybrid
Manual binding entries
Address binding is 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.
hardware-address hardware-address
Configure manual binding
OS10(config)# ip dhcp server
OS10(conf-dhcp)# pool static
OS10(conf-dhcp-static)# host 20.1.1.2
OS10(conf-dhcp-static)# hardware-address 00:01:e8:8c:4d:0a

With fixed host configuration (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.
