Configuring DHCP

DHCP Configuration Task List

Command	Purpose
Router(dhcp-config)# netbios-name-server	Specifies the NetBIOS WINS server that is available to a Microsoft
address [address2 ... address8]	DHCP client. One address is required; however, you can specify up to
	eight addresses in one command line.

Configuring the NetBIOS Node Type for the Client

The NetBIOS node type for Microsoft DHCP clients can be one of four settings: broadcast, peer-to-peer, mixed, or hybrid. To configure the NetBIOS node type for a Microsoft DHCP, use the following command in DHCP pool configuration mode:

Command	Purpose
Router(dhcp-config)# netbios-node-typetype	Specifies the NetBIOS node type for a Microsoft DHCP client.

Configuring the Default Router for the Client

After a DHCP client has booted, the client begins sending packets to its default router. The IP address of the default router should be on the same subnet as the client. To specify a default router for a DHCP client, use the following command in DHCP pool configuration mode:

Command	Purpose
Router(dhcp-config)# default-router	Specifies the IP address of the default router for a DHCP client. One IP
address [address2 ... address8]	address is required; however, you can specify up to eight addresses in one
	command line.

Configuring the Address Lease Time

By default, each IP address assigned by a DHCP Server comes with a one-day lease, which is the amount of time that the address is valid. To change the lease value for an IP address, use the following command in DHCP pool configuration mode:

Command	Purpose
Router(dhcp-config)# lease {days	Specifies the duration of the lease. The default is a one-day lease.

[hours][minutes] infinite}

•Use the show ip dhcp binding to display the lease expiration time and date of the IP address of the host.

Configuring Manual Bindings

An address binding is a mapping between the IP address and MAC address of a client. The IP address of a client can be assigned manually by an administrator or assigned automatically from a pool by a DHCP Server.
