Become superuser or assume a role or user name that is assigned to the DHCP Management profile.
For more information about the DHCP Management profile, see Setting Up User Access to DHCP Commands.

Modify one or more performance options:
# /usr/sbin/dhcpconfig -P keyword=value,keyword=value...
keyword=value can be any of the following keywords:
Specifies the maximum number of relay agent hops that can occur before the daemon drops the DHCP or BOOTP datagram.
Enables or disables automatic duplicate IP address detection. Setting this keyword to FALSE is not recommended.
Specifies the interval in minutes that the DHCP server should use to schedule the automatic rereading of the dhcptab information.
Specifies the number of seconds the DHCP server should cache the offers that are extended to discovering DHCP clients. The default setting is 10 seconds.
The following is an example of how to specify all the command options.
# dhcpconfig -P RELAY_HOPS=2,ICMP_VERIFY=TRUE,\ RESCAN_INTERVAL=30,OFFER_CACHE_TIMEOUT=20
