Excluding Addresses from the Address Pool
The DHCP server assumes that all IP addresses in a DHCP address pool are available for assigning to DHCP clients.
You must specify the IP address that the DHCP server should not assign to clients.
To exclude an address, follow this step.
•
Exclude an address range from DHCP assignment. The exclusion applies to all configured pools.
DHCP mode
excluded-address
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
298
