Customizing DHCP Services

Use the Modify Options dialog box to configure the following options.

Maximum Relay Agent Hops	Specify the maximum number of relay hops that can occur before the DHCP server drops the request. The default is 4.
Verbose Log Messages	The DHCP daemon writes messages to the syslogd facility. In verbose mode, the DHCP daemon displays more messages than in non-verbose mode. This can reduce efficiency due to the time taken to write and display the messages. The default is for non-verbose mode.
Log Transactions	Select whether to have the DHCP daemon log transactions using syslogd, and select an integer from 0 through 7 to specify the local syslog facility. The local syslog facility can be used to selectively view transaction messages generated by the DHCP daemon. Transactions include all DHCP messages between the daemon and clients. This feature may be useful in troubleshooting problems with DHCP.
Detect Duplicate IP Addresses	By default, the DHCP server pings an IP address before offering it to a DHCP or BOOTP client to verify that the address is not in use by another client. Uncheck the box to disable this action.
Reload dhcptab	Specify the interval, in minutes, that the DHCP server should use to schedule the rereading of the dhcptab information. The DHCP server reads the dhcptab at startup and not again until told to do so. Typically, the DHCP Manager causes the server to reread the dhcptab whenever you make a change to the data. The default is to turn off this option to avoid needless re-initialization of the dhcptab.
Cache Offers	Specify the number of seconds the server will hold open the offer to a client request for configuration. The default is 10 seconds. You can increase this time to compensate for slow performance on a slow network.
BOOTP Compatibility	Select whether to allow the DHCP server to operate in BOOTP compatibility mode. In this mode, the DHCP server will respond to requests for configuration from BOOTP clients. None Do not allow BOOTP compatibility. Automatic Automatically allocate permanent IP addresses to requesting BOOTP clients even if the clients are not registered in the server's database. Manual Respond only to clients that have been manually registered in the server's database.
Interfaces	Click the Interfaces tab to choose which network interfaces the DHCP server will monitor. The interfaces are listed by device name and network IP address. Use the arrow key to remove or restore a network interface to the list of monitored interfaces. The default is to allow the server to monitor all network interfaces.
