Detailed Description

Parser for the configuration of interfaces.

This parser parses the "interfaces-config" parameter which holds the full configuration of the DHCP server with respect to the use of interfaces, DHCP traffic sockets and alike.

This parser is used in both DHCPv4 and DHCPv6. Derived parsers are not needed.

Constructor & Destructor Documentation

IfacesConfigParser()

isc::dhcp::IfacesConfigParser::IfacesConfigParser	(	const uint16_t	protocol,
		bool	test_mode )

Constructor.

In test mode only the configuration is checked. In particular sockets are not opened or closed.

Parameters

protocol	AF_INET for DHCPv4 and AF_INET6 for DHCPv6.
test_mode	True if in test mode, False if not.

Definition at line 35 of file ifaces_config_parser.cc.

Member Function Documentation

parse()

void isc::dhcp::IfacesConfigParser::parse	(	const CfgIfacePtr &	config,
		const isc::data::ConstElementPtr &	values )

Parses content of the "interfaces-config".

Parameters

config	parsed structures will be stored here
values	pointer to the content of parsed values

Exceptions

DhcpConfigError

if the interface names and/or addresses are invalid.
