Description

Structure: TCPIP_DHCPS_CLIENT_OPTION_CONFIG

DHCP server configuration of client options

DHCP server configuration of provided client options
Lists the options to be presented to clients requiring an address lease

Remarks:

An option is allowed to appear multiple times.
For example, using TCPIP_DHCPS_CLIENT_OPTION_DNS 2 times, 2 DN servers will be communicated to the client

The maximum number of values possible for an option is dictated by:
    TCPIP_DHCPS_OPTION_ROUTER_VALUES     
    TCPIP_DHCPS_OPTION_DNS_VALUES        
    TCPIP_DHCPS_OPTION_TIME_SERVER_VALUES
    TCPIP_DHCPS_OPTION_NAME_SERVER_VALUES
    TCPIP_DHCPS_OPTION_NTP_SERVER_VALUES

    Excess values will be ignored.

Members


Members	Description
optType	Option type
ipStr	a string describing the option, a valid IP address string
	used for TCPIP_DHCPS_CLIENT_OPTION_ROUTER, TCPIP_DHCPS_CLIENT_OPTION_DNS, TCPIP_DHCPS_CLIENT_OPTION_TIME_SERVER,
	TCPIP_DHCPS_CLIENT_OPTION_NAME_SERVER, TCPIP_DHCPS_CLIENT_OPTION_NTP_SERVER
uintVal	a uint32_t value
mult, div	uint16_t values
	used for TCPIP_DHCPS_CLIENT_OPTION_T1_RENEWAL and TCPIP_DHCPS_CLIENT_OPTION_T2_REBINDING
	the T1 and T2 are obtained as percentages of lease time:
	T1 = (leaseTime * mult) / div; default values are mult = 1, div = 2;
	T2 = (leaseTime * mult) / div; default values are mult = 7, div = 8;
	Default values are used for mult or div if any of them are 0
	T2 needs to be greater than T1!
