Library /sys$common/syshlp/NCPHELP.HLB  —  LOAD  VIA
 Use the LOAD VIA command to downline load software to  a  target  node
 via  the  specified circuit.  The target node identification is obtained
 from the volatile database on the executor node.   If the target node is
 on a broadcast circuit, the PHYSICAL ADDRESS parameter must be specified
 in this command.

 LOAD    VIA circuit-id     (parameters ...)

 All underscores found in parameters must be replaced with spaces
 when parameters are used in NCP commands.

1  –  ADDRESS node-address 

 Identifies the address that the target node is to use (when
 it comes up).

2  –  CPU cpu-type 

 Identifies the target node's CPU type. There are four
 possibilities:

         DECSYSTEM1020
         PDP11
         PDP8
         VAX

3  –  FROM file-spec 

 Identifies the file specification of the load file
 containing the system software to be downline loaded.

4  –  HOST node-id 

 Identifies the default host that the target node is to use
 (when it comes up).

5  –  LOAD

5.1  –  ASSIST

5.1.1  –  AGENT 

 Specifies the VMS image that will define the system software for downline
 loading and adjacent node.

5.1.2  –  PARAMETER 

 Specifies a parameter to be passed to a load assist agent. The load assist
 agent can be used to tailor the system software to be loaded.

6  –  MANAGEMENT FILE 

 Specifies a file containing management information for downline loading
 to an adjacent node.

7  –  NAME node-name 

 Identifies the name that the target node is to use (when it
 comes up).

8  –  PHYSICAL ADDRESS address 

 Applies only to broadcast circuits.  Specifies the physical
 address that the target node to be loaded downline currently
 uses to identify itself.   The value is the physical address
 that the target node has set for itself or, if the target
 node has not set a physical address, the HARDWARE ADDRESS
 parameter if associated with the target node in the executor
 node's volatile database.

9  –  SECONDARY LOADER file-spec 

 Identifies the file specification of a secondary loader
 program which performs the downline load operation.

10  –  SERVICE 

 Introduces a service parameter.

 All underscores found in parameters must be replaced with spaces
 when parameters are used in NCP commands.

10.1  –  DEVICE device-type 

 Identifies the target node's line controller for the service circuit
 over which the operation is to take place.  The possibilities are
 as follows.

                BNA  CEC  DA   DL   DLV  DMB
                DMC  DMF  DMP  DMR  DMV  DP
                DQ   DSB  DSF  DSW  DTE  DU
                DUP  DV   DW4  DZ   EIA  EGA
 	       ELA  ERA  ETA  EWA  FPA  FZA
 	       ISA  KDP  KDZ  KL   LLA  MFA
 	       MNA  MXE  PCL  QNA  SVA  TRA
 	       TRE  TRP  UNA  VLA

 Only the synchronous port on the DMF service device may be used.

10.2  –  PASSWORD hex-password 

 Identifies the password required to trigger the bootstrap
 mechanism on the target node.  The password is a hexadecimal
 number.  For DDCMP circuits, it is in the range of 0 to FFFFFFFF;
 for broadcast circuits, it is in the range of 0 to FFFFFFFFFFFFFFFF.

11  –  SOFTWARE 

 Introduces a software parameter.

 All underscores found in parameters must be replaced with spaces
 when parameters are used in NCP commands.

11.1  –  IDENTIFICATION software-id 

 Identifies the ID of the software to be to be downline
 loaded.

11.2  –  TYPE software-type 

 Identifies a particular file type to be loaded. There are
 three possibilities:

                 MANAGEMENT FILE
                 SECONDARY LOADER
                 TERTIARY LOADER
                 SYSTEM

12  –  TERTIARY LOADER file-spec 

 Identifies the file specification of a tertiary loader
 program which performs the downline load function.

13  –  Examples 

      NCP>LOAD VIA DMP-0.4

          This command initiates a downline load operation over circuit
          DMP-0.4.  Any required default information is retrieved from
          the volatile database on the executor node.  NCP scans the
          node database until it finds a node whose service circuit
          matches the load circuit.

      NCP>LOAD VIA DMC-0 SOFTWARE TYPE SECONDARY LOADER

          This command initiates a downline load operation over circuit
          DMC-0, commencing with the secondary loader file.

      NCP>LOAD VIA UNA-0 PHYSICAL ADDRESS AA-00-04-00-07-04

          This command initiates a downline load operation over Ethernet
          circuit UNA-0, to the target node whose physical address is
          specified in the command.
