# Alphabetical error summary

All Natural Access functions return a status code of SUCCESS (0) or an error code indicating that the function failed and the reason for the failure.

Switching service error codes are defined in the swidef.h include file. The error codes are prefixed with SWIERR.

The following table lists the Switching service errors. All errors are 32 bits.

Error name | Hex | Decimal | Description
--- | --- | --- | ---
SWIERR_CONNECTION_NOT_SUPPORTED | 0x40011 | 262161 | Switch block does not support the requested connection. A permanent limitation in the switch block prevents the connection.
SWIERR_DEVICE_ERROR | 0x40002 | 262146 | MVIP device driver encountered an error while using the services of another device driver.
SWIERR_DLL_INVALID_DEVICE | 0x40001 | 262145 | Dynamic link library (DLL) could not find the requested device.
SWIERR_INTERNAL_CONFLICT | 0x40010 | 262160 | Switch component of a switch matrix conflicts with another switch component (the state of the switch matrix is ambiguous).
SWIERR_INVALID_CLOCK_PARM | 0x40007 | 262151 | Value of a clock configuration parameter is invalid. Enter a valid value.
SWIERR_INVALID_COMMAND | 0x40000 | 262144 | Device driver does not support the requested operation.
SWIERR_INVALID_MINOR_SWITCH | 0x4000B | 262155 | Value of the switch parameter is invalid.
SWIERR_INVALID_MODE | 0x4000A | 262154 | Device driver does not support the setting of the mode of an output terminus to the mode specified (for example, swiMakeFramedConnection is not supported in all hardware or by MVIP-90 drivers). Enter a valid mode. If you are using swiMakeFramedConnection on a board with the H.100 or H.110 bus, ensure that the statement SwitchConnectMode = AllConstantDelay is present in the board keyword file.
SWIERR_INVALID_PARAMETER | 0x4000C | 262156 | Parameter needed by the called function is set to an invalid value. Enter a valid value.
SWIERR_INVALID_SPEED | 0x40008 | 262152 | Invalid stream speed capacity was entered. This functionality works only in MVIP-95. Enter one of the following acceptable speed values: MVIP95_2MBPS_STREAM_SPEED MVIP95_4MBPS_STREAM_SPEED MVIP95_8MBPS_STREAM_SPEED
SWIERR_INVALID_STREAM | 0x40004 | 262148 | Value of stream in a terminus element is out of range. Enter a valid value for stream in the terminus element.
SWIERR_INVALID_TIMESLOT | 0x40005 | 262149 | Value of timeslot in a terminus element is out of range. Enter a valid value for timeslot in the terminus element.
SWIERR_MISSING_PARAMETER | 0x40006 | 262150 | Insufficient number of parameters were provided for the driver to complete the command.
SWIERR_MVIP_BUS_NOT_ENABLED | 0x40012 | 262162 | Switching command was called on a switch block on which the MVIP bus was not enabled. CLOCKING.HBUS.CLOCKMODE = Master_A, Master_B, or Slave in the board keyword file for the switch block.
SWIERR_NO_PATH | 0x4000E | 262158 | Device driver is unable to complete the connection because there is blocking or some other temporary switch limitation encountered.
SWIERR_NOT_CONFIGURABLE | 0x40009 | 262153 | Device does not support configuration of the requested parameters, values, or both.
SWIERR_SWITCH_VERIFY_ERROR | 0x4000F | 262159 | Verification of the switch operation failed.
SWIERR_UNSUPPORTED_MODE | 0x4000D | 262157 | Mode is not supported by either the device driver or the hardware below the driver.
