Hi,
I have the following MIB and I am trying to
populate some of the variables(prtGeneralCurrentLocalization) let say
with some values (30).
I have used mib2c and create-data-set to generate the code's skeleton.
Before compiling and running the subagent:
if I do a snmpwalk on prtGeneralTable as following:
snmpwalk -v 1 -c public localhost prtGeneral
I
get nothing, no errors,....????? Does that mean that the rows are just
not there yet ? (other walks on other objects work fine)
If I now run the subagent I still have the same result.
Below is the code I use for initialization as well as the MIB used for this
purpose.
I hope someone will help. Thanks!
