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. |
