The CLEAR CIRCUIT command resets circuit parameters in the volatile
 database to the default value (if any), or removes them from the volatile
 database on the local node or DTE.

 The PURGE CIRCUIT command always removes circuit parameters from the
 permanent database on the local node or DTE.

 CLEAR   KNOWN CIRCUITS        (parameters...)
         CIRCUIT circuit-id

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

1  –  KNOWN CIRCUITS

 Resets to the default value (if any) or removes from the volatile
 database the parameters for all known circuits.

2  –  CIRCUIT circuit-id

 Resets to the default value (if any) or removes from the volatile
 database the parameters for a specific circuit. Circuit-id specifies the
 name of the circuit you want to clear.

3  –  ACTIVE

 Differentiates between the active, inactive and dying DDCMP timer
 parameters.

3.1  –  BASE

 Applies only to DDCMP CONTROL circuits. Resets to its default value the
 ACTIVE BASE value in the volatile database.

3.2  –  INCREMENT

 Applies only to DDCMP CONTROL circuits.  Resets to its default value the
 ACTIVE INCREMENT value in the volatile database.

4  –  ALL

 Removes from the volatile database the specified circuit or all known
 circuits.  The circuit must be in the OFF state before you can specify
 this parameter.

5  –  BABBLE TIMER

 Applies only to DDCMP CONTROL circuits.  Resets to its default value the
 BABBLE TIMER value in the volatile database.

6  –  COUNTER TIMER

 Cancels the logging timer.  This cancellation prevents any further circuit
 counter logging for the indicated circuit or circuits.

7  –  DEAD THRESHOLD

 Applies only to DDCMP CONTROL circuits.  Resets to its default value the
 DEAD THRESHOLD value in the volatile database.

8  –  DYING

 Differentiates between the active, inactive and dying DDCMP timer
 parameters.

8.1  –  BASE

 Applies only to DDCMP CONTROL circuits.  Resets to its default value the
 DYING BASE value in the volatile database.

8.2  –  INCREMENT

 Applies only to DDCMP CONTROL circuits.  Resets to its default value the
 DYING INCREMENT value in the volatile database.

8.3  –  THRESHOLD

 Applies only to DDCMP CONTROL circuits.  Resets to its default value the
 DYING THRESHOLD value in the volatile database.

9  –  INACTIVE

 Differentiates between the active, inactive and dying DDCMP timer
 parameters.

9.1  –  BASE

 Applies only to DDCMP CONTROL circuits.  Resets to its default value the
 INACTIVE BASE value in the volatile database.

10  –  INCREMENT

 Applies only to DDCMP CONTROL circuits.  Resets to its default value the
 INACTIVE INCREMENT value in the volatile database.

11  –  THRESHOLD

 Applies only to DDCMP CONTROL circuits.  Resets to its default value the
 INACTIVE THRESHOLD value in the volatile database.

12  –  MAXIMUM

 This modifier indicates an upper limit on a variety of parameters.

12.1  –  BUFFERS

 Applies only to DDCMP CONTROL circuits.  Resets to its default value the
 MAXIMUM BUFFERS value in the volatile database.

12.2  –  RECALLS

 Applies only to X25 DLM circuits.  Resets to its default value the limit
 on the number of call retries.

12.3  –  ROUTERS

 Applies only to broadcast circuits.  Resets to its default value the
 MAXIMUM ROUTER value in the volatile database.

12.4  –  TRANSMITS

 Applies only to DDCMP CONTROL circuits.  Resets to its default value the
 MAXIMUM TRANSMITS value in the volatile database.

13  –  NETWORK

 Applies only to purging X25 PVCs and X25 DLM circuits.  Removes the
 circuit's network parameters from the permanent database.

14  –  RECALL TIMER

 Applies only to X25 DLM circuits.  Resets to its default value the RECALL
 TIMER value in the volatile database.

15  –  ROUTER PRIORITY

 Applies only to broadcast circuits.  Resets to its default value the
 priority assigned to the router in the volatile database.

16  –  TRANSMIT TIMER

 Applies only to DDCMP CONTROL circuits.  Resets to its default value the
 TRANSMIT TIMER value in the volatile database.

17  –  Examples

      NCP>CLEAR CIRCUIT DMC-0 ALL

          This command removes all parameter entries for circuit
          DMC-0 in the volatile database.  As a result, the circuit
          no longer exists for the executor DECnet software.
