The OID is this one:
.1.3.6.1.2.1.11.32
SNMPv2-MIB::snmpProxyDrops
snmpProxyDrops OBJECT-TYPE
-- FROM SNMPv2-MIB
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION "The total number of Confirmed Class PDUs
(such as GetRequest-PDUs, GetNextRequest-PDUs,
GetBulkRequest-PDUs, SetRequest-PDUs, and
InformRequest-PDUs) delivered to the SNMP entity which
were silently dropped because the transmission of
the (possibly translated) message to a proxy target
failed in a manner (other than a time-out) such that
no Response Class PDU (such as a Response-PDU) could
be returned."

Most of the debug output seems to be indexing and parsing your MIBs (I counted 336 of them). At the end, the device returns "0" as the answer to the poll:
.1.3.6.1.2.1.11.32.0 = Counter32: 0
Hope this helps.
