Configuring the DHCP Server
7.5 Using DHCP GUI to Configure DHCP
Static Routes
Specifies a list of static routes that should be installed in the client’s routing table.
If you specify multiple routes to the same destination, list them in descending
order of priority.
The routes consist of a list of IP address pairs. The first address is the destination
address, and the second address is the router for the destination.
Note
The default route (0.0.0.0) is an illegal destination for a static route.
Use this format: ddd.ddd.ddd.ddd.
Subnets Are Local
Specifies whether the client can assume that all subnets of the IP network to
which the client is connected use the same MTU (maximum transmit unit) as the
subnet of the network to which the client is directly connected.
The following are valid values:
False: The client should assume that some subnets of the directly connected network
can have smaller MTUs.
True: All subnets share the same MTU.
Supply Masks
Specifies whether the client should respond to subnet mask requests using the
Internet Control Message Protocol (ICMP).
The following are valid values:
False: Client should not respond.
True: Client should respond.
7.5.3.4.5 Lease parameters Lease parameters allow you to change information
about the IP lease times. Lease times determine the length of time a client can
use an IP address.
DHCP Rebinding Time
Specifies the time interval in seconds from address assignment until the client
requests a new lease from any server on the network.
DHCP Renewal Time
Specifies the time interval in seconds from address assignment until the client
attempts to extend the duration of its lease with the original server.
DHCP Lease Time
The client uses this option in a client request (DHCPDISCOVER or
DHCPREQUEST) message to request a lease time for the IP address.
The server uses this option in a server reply (DHCPOFFER) message to specify
the lease time it is willing to offer.
Enter the time in months, days, hours, minutes, and seconds; for example, 2
months 5 days 45 minutes. By default, the server interprets the lease in seconds.
For an infinite lease for a BOOTP client, specify a -1.
