6.3.8 Debug Command Group
sfdebug {es-1fe 8}
This attribute group provides access to the built-in debugging resources. Access
to these functions requires the use of the sfadminAnyPass.
To examine the FN100’s memory, the NMS must perform the following steps:
1. Set sfdebugIndex with the identifier of the selected port or the MP.
2. Set sfdebugBase with the desired base address.
3. Set sfdebugLength with the desired location count.
4. Set sfdebugData to NULL, so that the FN100’s GetResponse PDU will
include the current value of sfdebugData (i.e., the contents of the desired
memory locations).
5. Set sfdebugOperation with the examine (1) value. All of the above “sets”
must be performed in a single SetRequest PDU, with sfdebugOperation being
the last parameter. This will cause the FN100 to read the desired memory
locations, update the sfdebugLength and sfdebugData parameters, and return
the updated parameters in the GetResponse PDU.
To modify the FN100’s memory, the NMS must perform the following steps:
1. Set sfdebugBase with the desired base address.
2. Set sfdebugLength with the desired location count.
3. Set sfdebugData to contain the desired new data.
