Hello every body,
I did a lot of playing recently with registering handlers for extended range
of the oids. When I setup up range_subid to the *length* of the registration
oid of the handler (and also setup some upper limit with range _ubound),
appropriate handler is *not called* for range above the rootoid of the
registration.
EXAMPLE code:
====================================================================
static oid dsx1IntervalIndex_oid[] =
{ 1, 3, 6, 1, 2, 1, 10, 18, 8, 1, 1, 101 };
netsnmp_create_handler_registration("dsx1IntervalIndex",
handle_dsx1IntervalIndex,
dsx1IntervalIndex_oid,
OID_LENGTH
(dsx1IntervalIndex_oid),
HANDLER_CAN_RONLY);
handler_reginfo->range_subid = OID_LENGTH(dsx1IntervalIndex_oid);
handler_reginfo->range_ubound = 108;

Does anybody have any experience with that? By the way, I'm using 5.1.1.
Bye, have a nice day,
