Re: Problem initializing table from mib2c data_set

Dave,

Just to make my question a little clear. How can I enable a rows (created with dataset mib2c) let say :

myoid.COLUMN_ROW1.1
myoid.COLUMN_ROW2.1

to respond to GET request because they are currently responding only to GETNEXT requests.
I hope this was a little more clear.

Thanks for your help.

Yan~

Those two statements mean that you can create new rows in the table,
using an SNMP SET command, and it will provide a default value for
these two objects.

Though since prtConsoleDisplayBufferIndex is one of the indexes of
the table, you would presumably be running SET command on the
prtConsoleDisplayBufferText object anyway,  so these default values
are somewhat redundant.

That indicates the column, not the row.
If you are creating a new row, then you need to specify the index
values for that row.   The agent can't make these indexes up
automatically - you need to tell it what to do.

Yes - that's how this is meant to work.
Although judging by your code, there ought to be two index values,
not just one.

That's not how SNMP tables work.   You *always* have to specify the
index values.
That's the whole point of a table!
    Management values are associated with an _instance_ of a column object (i.e.
a particular row of the table),  not with the column as a whole.
