Hello,
i try to initialize some entries within a table,
but every time i get only the last insrted entry from the table.
It looks like an table iterator problem. I'm sure there are two entries.
The followed request should gives the specific table entries.
snmptable -v 2c -c public -Cf + localhost 1.3.6.1.4.1.26958.25.3.2
I hope any can help?
If an ifTable index responible?
