Definition at line 47 of file simple_parser4.h.

◆ GLOBAL4_DEFAULTS

const SimpleDefaults isc::dhcp::SimpleParser4::GLOBAL4_DEFAULTS

static

Initial value:

= {
    { "valid-lifetime",           Element::integer, "7200" },
    { "decline-probation-period", Element::integer, "86400" }, 
    { "dhcp4o6-port",             Element::integer, "0" },
    { "echo-client-id",           Element::boolean, "true" },
    { "match-client-id",          Element::boolean, "true" },
    { "authoritative",            Element::boolean, "false" },
    { "next-server",              Element::string,  "0.0.0.0" },

    { "boot-file-name",           Element::string,  "" },
    { "server-tag",               Element::string,  "" },
    { "reservation-mode",         Element::string,  "all" }
}

This table defines default global values for DHCPv4.

Some of the global parameters defined in the global scope (i.e. directly in Dhcp4) are optional. If not defined, the following values will be used.

Definition at line 42 of file simple_parser4.h.

◆ IFACE4_DEFAULTS

const SimpleDefaults isc::dhcp::SimpleParser4::IFACE4_DEFAULTS

static

Initial value:

= {
    { "re-detect", Element::boolean, "true" }
}

This table defines default values for interfaces for DHCPv4.

Definition at line 46 of file simple_parser4.h.

◆ INHERIT_TO_SUBNET4

const ParamsList isc::dhcp::SimpleParser4::INHERIT_TO_SUBNET4

static

Initial value:

= {
    "boot-file-name",
    "client-class",
    "interface",
    "match-client-id",
    "authoritative",
    "next-server",
    "rebind-timer",
    "relay",
    "renew-timer",
    "reservation-mode",
    "server-hostname",
    "valid-lifetime"
}

List of parameters that can be inherited to subnet4 scope.

Some parameters may be defined on both global (directly in Dhcp4) and subnet (Dhcp4/subnet4/...) scope. If not defined in the subnet scope, the value is being inherited (derived) from the global scope. This array lists all of such parameters.

This list is also used for inheriting from global to shared networks and from shared networks to subnets within it.

Definition at line 48 of file simple_parser4.h.

◆ OPTION4_DEF_DEFAULTS

const SimpleDefaults isc::dhcp::SimpleParser4::OPTION4_DEF_DEFAULTS

static

Initial value:

= {
    { "record-types", Element::string,  ""},
    { "space",        Element::string,  "dhcp4"},
    { "array",        Element::boolean, "false"},
    { "encapsulate",  Element::string,  "" }
}

This table defines default values for option definitions in DHCPv4.

Dhcp4 may contain an array called option-def that enumerates new option definitions. This array lists default values for those option definitions.

Definition at line 40 of file simple_parser4.h.

◆ OPTION4_DEFAULTS

const SimpleDefaults isc::dhcp::SimpleParser4::OPTION4_DEFAULTS

static

Initial value:

= {
    { "space",        Element::string,  "dhcp4"},
    { "csv-format",   Element::boolean, "true"},
    { "always-send",  Element::boolean, "false"}
}

This table defines default values for options in DHCPv4.

Dhcp4 usually contains option values (option-data) defined in global, subnet, class or host reservations scopes. This array lists default values for those option-data declarations.

Definition at line 41 of file simple_parser4.h.

◆ SHARED_NETWORK4_DEFAULTS

const SimpleDefaults isc::dhcp::SimpleParser4::SHARED_NETWORK4_DEFAULTS

static

Initial value:

= {
    { "client-class",     Element::string, "" },
    { "interface",        Element::string, "" }
}

This table defines default values for each IPv4 shared network.

Definition at line 45 of file simple_parser4.h.

◆ SHARED_SUBNET4_DEFAULTS

const SimpleDefaults isc::dhcp::SimpleParser4::SHARED_SUBNET4_DEFAULTS

static

Initial value:

= {
    { "id",               Element::integer, "0" }, 
    { "4o6-interface",    Element::string,  "" },
    { "4o6-interface-id", Element::string,  "" },
    { "4o6-subnet",       Element::string,  "" },
}

This table defines default values for each IPv4 subnet that is part of a shared network.

This is mostly the same as SUBNET4_DEFAULTS, except two parameters that can be derived from shared-network, but cannot from global scope. Those are: interface and reservation-mode.

Definition at line 44 of file simple_parser4.h.

◆ SUBNET4_DEFAULTS

const SimpleDefaults isc::dhcp::SimpleParser4::SUBNET4_DEFAULTS

static

Initial value:

= {
    { "id",               Element::integer, "0" }, 
    { "interface",        Element::string,  "" },
    { "client-class",     Element::string,  "" },
    { "4o6-interface",    Element::string,  "" },
    { "4o6-interface-id", Element::string,  "" },
    { "4o6-subnet",       Element::string,  "" },
}

This table defines default values for each IPv4 subnet.

Note: When updating this array, please also update SHARED_SUBNET4_DEFAULTS below. In most cases, those two should be kept in sync, except cases where a parameter can be derived from shared-networks, but is not defined on global level. Currently there are two such parameters: interface and reservation-mode
