APPENDIX C
ERROR CODES
The Return Status word in the command response contains information pertaining to the status of the IOPBs returned
in the Command Response Block. Error codes are reported in hexadecimal format.
HEX CODE
DESCRIPTION
0x110 VMEbus Error
An attempted VME bus transfer generated a system bus error.
0x115 Abort Pending Error
The errored command is being returned in response to an abort command issued by the MAC Status
IOPB.
0x120 Transmit Error
An error occurred while attempting to transmit frame. Currently, transmit commands are returned
immediately after the DMA transfer of the frame data from the host is complete, so transmit errors
will not be reported back to the host. Use the network statistics command to obtain counts of errored
transmits instead.
0x121 Network Interface Not Initialized
An operation was attempted on an uninitialized network interface.
0x141 Illegal Option
An illegal option was specified in the command options word of an IOPB. Note that only obvious
illegal combinations will generate this error: fully sanity checking for all possible illegal
combinations is not feasible.
0x142 Illegal MAC Option
An illegal option was specified in the MAC status word of the MAC Status IOPB.
0x143 Illegal Parameter
The submitted IOPB could not be processed due to an error in one of the fields.
0x144 Bus Error
A system bus error occurred. This error code is identical in meaning to 0x110, and will be replaced
by it.
0x145 Link Status Error
An attempt was made to perform some function using the MAC Status IOPB on a network interface
that was in a Link UP state.
