Specifying an Address Lease Time
To specify an address lease time, use the following command.
• Specify an address lease time for the addresses in a pool.
DHCP <POOL>
lease {days [hours] [minutes] | infinite}
The default is 24 hours .
Specifying a Default Gateway
The IP address of the default router should be on the same subnet as the client.
To specify a default gateway, follow this step.
• Specify default gateway(s) for the clients on the subnet, in order of preference.
DHCP <POOL>
default-router address
Configure a Method of Hostname Resolution
Dell systems are capable of providing DHCP clients with parameters for two methods of hostname
resolution—using DNS or NetBIOS WINS.
Using DNS for Address Resolution
A domain is a group of networks. DHCP clients query DNS IP servers when they need to correlate host
names to IP addresses.
1. Create a domain.
DHCP <POOL>
domain-name name
2. Specify in order of preference the DNS servers that are available to a DHCP client.
DHCP <POOL>
dns-server address
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.
