Configuring the DHCP Server
7.5 Using DHCP GUI to Configure DHCP
The following are valid values:
False: Do not send an ICMP echo request to a BOOTP client before assigning an IP
address. Default.
True: Send an ICMP echo request to a BOOTP client before assigning an IP address.
Ping Timeout
Specifies the duration (in milliseconds) of the ping timeout. Enter the amount of
time the server is to wait before concluding no other host is using the IP address.
After the timeout, the ping command stops checking.
If you do not want the server to ping before giving out an IP address, set the
timeout value to 0.
The default is 500 milliseconds.
Provisional Time To Live
Specifies the maximum time period that an IP address can remain on the
provisionally allocated list before it can be allocated to another client. The
value should be limited to a few minutes.
The default is 1 minute.
Reply to Relay On Local Net
Specifies whether the server ignores packets forwarded to it from a relay agent
on the same subnet as the server.
The following are valid values:
False: Do not reply (the server should hear the client broadcast directly). Default.
True: Reply no matter where the agent is located (the value in giaddr field).
Restrict to Known MAC Addresses
Specifies whether to restrict IP addresses that are assigned to a matching
MAC address. When specified, you can manually assign a MAC address. This
parameter indicates whether the server should respond to clients with a MAC
address that is unknown to the server.
Choose True to have the server provide DHCP information to only those hosts
that have a known MAC address. To register a known MAC address client, use
Preload MAC Addresses feature from the Server/Security tab or use the DBREG
utility.
The following are valid values:
False: Do not allow manual assignment of MAC addresses. Default.
True: Allow manual assignment of MAC addresses.
Send Options in DHCP Offer
Specifies whether the server is to send a complete configuration to a DHCP
client. Resolving a client configuration can be time consuming. In a multiserver
environment, the client can select another server.
The following are valid values:
False: Send a minimum configuration. Default.
True: Send a complete configuration.
