NAME

Net::DHCP::Constants - Constants for DHCP codes and options

CONTENTS

VERSION

version 0.696

SYNOPSIS



  use Net::DHCP::Constants;
  print "DHCP option SUBNET_MASK is ", DHO_SUBNET_MASK();



DESCRIPTION

Represents constants used in DHCP protocol, defined in RFC 1533, RFC 2132, RFC 2241, RFC 2485, RFC 2563, RFC 2937, RFC 3004, RFC 3011, RFC 3046.

TAGS

As mentioned above, constants can either be imported individually or in sets grouped by tag names. The tag names are:
o bootp_codes

Imports all of the basic BOOTP constants.



  (01) BOOTREQUEST
  (02) BOOTREPLY



o htype_codes

Imports all HTYPE (hardware address type) codes.



  (01) HTYPE_ETHER
  (06) HTYPE_IEEE802
  (08) HTYPE_FDDI



Most common value is HTYPE_ETHER for Ethernet.

o dhcp_message

Import all DHCP Message codes.

(rfc2132)



  (01) DHCPDISCOVER
  (02) DHCPOFFER
  (03) DHCPREQUEST
  (04) DHCPDECLINE
  (05) DHCPACK
  (06) DHCPNAK
  (07) DHCPRELEASE
  (08) DHCPINFORM
  (09) DHCPFORCERENEW



(rfc4388)



  (10) DHCPLEASEQUERY
  (11) DHCPLEASEUNASSIGNED
  (12) DHCPLEASEUNKNOWN
  (13) DHCPLEASEACTIVE



Nb. Previously Cisco used 13 for DHCPLEASEQUERY. If you need to decode or encode packets to communicate with such a system, you might simply use the integer rather than the constant - or use the updated constant and comment in your code appropriately.

o dho_codes

Import all DHCP option codes.
