DHCP DHC DH

Description:

Enables individual units on an IP network to extract their IP Address from a DHCP server. The overall purpose of this is to reduce the work necessary for administration of a large IP network. Consult your Network Administrator before using DHCP. This setting requires the presence of a DHCP server on the LAN. Also, the DHCP server needs to be able to notify a DNS server of the IP address associated with the unit name (which is the hostname). Performing a configuration save with DHCP on will save the currently allocated IP Address and other parameters obtained by the DHCP server and potentially create problems for the network. Contact the Network Administrator for static IP address.

Response:

  MODIFY DHCP RESPONSE
    Verbose- "OK\r\n" to acknowledge receipt of command, or
             "ERROR- [Description]\r\n" if error, ending command
    Terse-   "0\r\n" to acknowledge receipt of command, or
             "[NON-ZERO NUMERIC VALUE]\r\n" if error, ending command
    "\r\n" concludes modify responses (empty line)

  DISPLAY DHCP RESPONSE
    Verbose- "OK\r\n" to acknowledge receipt of command, followed by
             "DHCP= [STANDARD]\r\n", or
             "ERROR- [Description]\r\n" if error, ending command
    Terse-   "0\r\n" to acknowledge receipt of command, followed by
             "[TERSE NUMERIC VALUE]\r\n", or
             "[NON-ZERO NUMERIC VALUE]\r\n" if error, ending command
    "\r\n" concludes display responses (empty line)

Examples:

  Verbose command to retrieve current setting:
  *.SYSD DHCP <enter>
     Response is: OK\r\n
                  DHCP= OFF\r\n

  Terse command to retrieve current setting:
  *.SYSD DH <enter>
     Response is: 0\r\n
                  0\r\n

  Verbose command to change setting:
  *.SYSD DHCP ON <enter>
     Response is: OK\r\n

  Terse command to change setting:
  *.SYSD DH 1<enter>
     Response is: 0\r\n

Notes:

  DHCP -  Dynamic Host Configuration Protocol

  The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for automating
  the configuration of network parameters. DHCP can be used in a Soloist to automatically
  assign IP address, Gateway IP address, and Subnet IP mask.  Also, the Soloist will supply
  its Unit name to the DHCP server as its hostname, and the DHCP server can then notify
  a DNS server that this units IP address is associated with unitname.domainname since the
  IP address is transparent to the remote user.<p>
  When the DHCP configuration parameter is set to ON, the Soloist will shutdown all networking
  and restart it, searching for a DHCP server.  If no DHCP server is found, the unit cannot
  obtain an IP address, and therefore, no TCP/IP communication can be done to the unit. The
  unit will continue to try to locate a DHCP server indefinitely or until the DHCP parameter is
  set to OFF.  If a DHCP server is located and an IP address is successfully obtained from it,
  the unit will start TCP/IP networking utilizing that IP address (subnet mask, and Gateway
  IP).  The configuration variables will reflect the values that were obtained through the
  use of DHCP
