       dhcp - Dynamic Host Configuration Protocol

       Dynamic  Host  Configuration  Protocol (DHCP) enables host systems in a
       TCP/IP network to be configured automatically for the network  as  they
       boot.  DHCP uses a client/server mechanism: servers store configuration
       information for clients, and provide that information upon  a  client's
       request. The information can include the client's IP address and infor-
       mation about network services available to the client.

       This manual page provides a brief summary of the Solaris DHCP implemen-

   Solaris DHCP Client
       The  Solaris  DHCP  client  is implemented as background daemon, dhcpa-
       gent(1M). This daemon is started automatically during bootup  if  there
       exists at least one dhcp.interface file in /etc. Only interfaces with a
       corresponding /etc/dhcp.interface  file  are  automatically  configured
       during  boot. Network parameters needed for system configuration during
       bootup are extracted  from  the  information  recieved  by  the  daemon
       through the use of the dhcpinfo(1) command. The daemon's default behav-
       ior can be altered by changing the tunables in the  /etc/default/dhcpa-
       gent  file. The daemon is controlled by the ifconfig(1M) utility. Check
       the status of the daemon using the netstat(1M)  and  ifconfig(1M)  com-

   Solaris DHCP Server
       The  Solaris  DHCP  server  is  implemented  as  a  background  daemon,
       in.dhcpd(1M). This daemon can deliver network configuration information
       to  either  BOOTP or DHCP clients. The Solaris DHCP service can be man-
       aged using the dhcpmgr(1M) GUI or the command line  utilities  dhcpcon-
       fig(1M), dhtadm(1M), and pntadm(1M).

   DHCP Configuration Tables
       The  Solaris DHCP server stores client configuration information in the
       following two types of tables:

       dhcptab tables          Contain macros and options (also known as  sym-
                               bols),  used to construct a package of configu-
                               ration information to send to each DHCP client.
                               There exists only one dhcptab for the DHCP ser-
                               vice. The dhcptab(4) can be viewed and modified
                               using  the  dhtadm(1M)  command  or dhcpmgr(1M)
                               graphical  utility.  See  dhcptab(4)  for  more
                               information   about   the   syntax  of  dhcptab
                               records. See dhcp_inittab(4) for more  informa-
                               tion about the DHCP options and symbols.

       DHCP network tables     DHCP  network tables, which contain mappings of
                               client IDs to IP addresses and parameters asso-
                               ciated with those addresses. Network tables are
                               named with the IP address of the  network,  and
                               can  be created, viewed, and modified using the
                               pntadm command or  dhcpmgr  graphical  utility.
                               See  dhcp_network(4) for more information about
                               network tables.
