STATUS deprecated
DESCRIPTION
The number of packets, delivered by this sub-layer to a higher (sub-)layer, which were addressed to
a multicast or broadcast address at this sub-layer. Discontinuities in the value of this counter can
occur at re-initialization of the management system, and at other times as indicated by the value of
ifCounterDiscontinuityTime.
This object is deprecated in favour of ifInMulticastPkts and ifInBroadcastPkts.

STATUS current
DESCRIPTION
The number of inbound packets which were chosen to be discarded even though no errors had been
detected to prevent their being deliverable to a higher-layer protocol. One possible reason for
discarding such a packet could be to free up buffer space. Discontinuities in the value of this counter
can occur at re-initialization of the management system, and at other times as indicated by the value
of ifCounterDiscontinuityTime.
::= { ifEntry 13 }
ifInErrors OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
For packet-oriented interfaces, the number of inbound packets that contained errors preventing them
from being deliverable to a higher-layer protocol. For character-oriented or fixed-length interfaces,
the number of inbound transmission units that contained errors preventing them from being
deliverable to a higher-layer protocol.
Discontinuities in the value of this counter can occur at re-initialization of the management system,
and at other times as indicated by the value of ifCounterDiscontinuityTime.

ifInUnknownProtos OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
For packet-oriented interfaces, the number of packets received via the interface which were
discarded because of an unknown or unsupported protocol. For character-oriented or fixed-length
interfaces that support protocol multiplexing the number of transmission units received via the
interface which were discarded because of an unknown or unsupported protocol. For any interface
that does not support protocol multiplexing, this counter will always be 0.
