Using NetBIOS WINS for Address Resolution
Windows internet naming service (WINS) is a name resolution service that Microsoft DHCP clients use to correlate host names to IP
addresses within a group of networks. Microsoft DHCP clients can be one of four types of NetBIOS nodes: broadcast, peer-to-peer,
mixed, or hybrid.
1. Specify the NetBIOS WINS name servers, in order of preference, that are available to Microsoft Dynamic Host Configuration Protocol
(DHCP) clients.
DHCP <POOL> mode
netbios-name-server address
2. Specify the NetBIOS node type for a Microsoft DHCP client. Dell Networking recommends specifying clients as hybrid.
DHCP <POOL> mode
netbios-node-type type
Creating Manual Binding Entries
An 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. However, the
administrator can manually create an entry for a client; manual bindings are useful when you want to guarantee that a particular network
device receives a particular IP address. Manual bindings can be considered single-host address pools. There is no limit on the number of
manual bindings, but you can only configure one manual binding per host.
NOTE:
The system does not prevent you from using a network IP as a host IP; be sure to not use a network IP as a host
IP.
1. Create an address pool.

2. Specify the client IP address.
DHCP <POOL>

3. Specify the client hardware address.
DHCP <POOL>
hardware-address hardware-address type
• hardware-address: the client MAC address.
• type: the protocol of the hardware platform.
The default protocol is Ethernet.
Debugging the DHCP Server
To debug the DHCP server, use the following command.
• Display debug information for DHCP server.
EXEC Privilege mode
debug ip dhcp server [events | packets]
Using DHCP Clear Commands
To clear DHCP binding entries, address conflicts, and server counters, use the following commands.
• Clear DHCP binding entries for the entire binding table.
