CCSDS File Delivery Protocol management commands file

## NAME

cfdprc - CCSDS File Delivery Protocol management commands file

## DESCRIPTION

CFDP management commands are passed to **cfdpadmin** either in a file of text lines or interactively at **cfdpadmin**'s command prompt (:).  Commands are interpreted line-by line, with exactly one command per line.  The formats and effects of the CFDP management commands are described below.

## COMMANDS

- **?**

  The **help** command.  This will display a listing of the commands and their formats.  It is the same as the **h** command.

- **#**

  Comment line.  Lines beginning with **#** are not interpreted.

- **e** { 1 \| 0 }

  Echo control.  Setting echo to 1 causes all output printed by cfdpadmin to be logged as well as sent to stdout.  Setting echo to 0 disables this behavior.

- **v**

  Version number.  Prints out the version of ION currently installed.  HINT: combine with **e 1** command to log the version number at startup.

- **1**

  The **initialize** command.  Until this command is executed, CFDP is not in operation on the local ION node and most *cfdpadmin* commands will fail.

- **i**

  The **info** This command will print information about the current state of the local CFDP entity, including the current settings of all parameters that can be managed as described below.

- **s** '*UTS command*'

  The **start** command.  This command starts the UT-layer service task for the local CFDP entity.

- **m discard** { 0 \| 1 }

  The **manage discard** command.  This command enables or disables the discarding of partially received files upon cancellation of a file reception.

- **m requirecrc** { 0 \| 1 }

  The **manage CRC data integrity** command.  This command enables or disables the attachment of CRCs to all PDUs issued by the local CFDP entity.

- **m fillchar** *file\_fill\_character*

  The **manage fill character** command.  This command establishes the fill character to use for the portions of an incoming file that have not yet been received.  The fill character is normally expressed in hex, e.g., 0xaa.

- **m ckperiod** *check\_cycle\_period*

  The **manage check interval** command.  This command establishes the number of seconds following reception of the EOF PDU -- or following expiration of a prior check cycle -- after which the local CFDP will check for  completion of a file that is being received.

- **m maxtimeouts** *check\_cycle\_limit*

  The **manage check limit** command.  This command establishes the number of check cycle expirations after which the local CFDP entity will invoke the check cycle expiration fault handler upon expiration of a check cycle.

- **m maxtrnbr** *max\_transaction\_number*

  The **manage transaction numbers** command.  This command establishes the largest possible transaction number used by the local CFDP entity for file transmission transactions.  After this number has been used, the  transaction number assigned to the next transaction will be 1.

- **m segsize** *max\_bytes\_per\_file\_data\_segment*

  The **manage segment size** command.  This command establishes the number of bytes of file data in each file data PDU transmitted by the local CFDP entity in the absence of an application-supplied reader function.

- **m inactivity** *inactivity\_period*

  The **manage inactivity period** command. This command establishes the number of seconds that a CFDP file transfer is allowed to go idle before being canceled for inactivity. The default is one day.

- **x**

  The **stop** command.  This command stops the UT-layer service task for the local CFDP engine.

- **w** { 0 \| 1 \| \<activity\_spec\> }

  The **CFDP watch** command.  This command enables and disables production of a continuous stream of user-selected CFDP activity indication characters.  A watch parameter of "1" selects all CFDP activity indication characters; "0" de-selects all CFDP activity indication characters; any other *activity\_spec* such as "p" selects all activity indication characters in the string, de-selecting all others.  CFDP will print each selected activity indication character to **stdout** every time a processing event of the associated type occurs:

  **p**	CFDP PDU transmitted

  **q**	CFDP PDU received

- **h**

  The **help** command.  This will display a listing of the commands and their formats.  It is the same as the **?** command.

## EXAMPLES

- m requirecrc 1

  Initiates attachment of CRCs to all subsequently issued CFDP PDUs.
