Errors Input/
Output
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.
For packet-oriented interfaces, the number of outbound packets that
could not be transmitted because of errors. For character-oriented or
fixed-length interfaces, the number of outbound transmission units
that could not be transmitted because of errors.
Unicast Packets
Input/Output
The number of packets, delivered by this sub-layer to a higher (sub-)
layer, which were not addressed to a multicast or broadcast address at
this sub-layer. The total number of packets that higher-level protocols
requested be transmitted, and which were not addressed to a multicast
or broadcast address at this sub-layer, including those that were dis-
carded or not sent.
Multicast Pack-
ets Input/Output
The number of packets, delivered by this sub-layer to a higher (sub-)
layer, which were addressed to a multicast address at this sub-layer.
For a MAC layer protocol, this includes both Group and Functional
addresses. The total number of packets that higher-level protocols
requested be transmitted, and which were addressed to a multicast
address at this sub-layer, including those that were discarded or not
sent. For a MAC layer protocol, this includes both Group and Func-
tional addresses.
Broadcast Pack-
ets Input/Output
The number of packets, delivered by this sub-layer to a higher (sub-)
layer, which were addressed to a broadcast address at this sub-layer.
The total number of packets that higher-level protocols requested be
transmitted, and which were addressed to a multicast address at this
sub-layer, including those that were discarded or not sent.
For a MAC layer protocol, this includes both Group and Functional
addresses.
Discards Input/
Output
The number of inbound packets chosen to be discarded to possibly
free up buffer space.
Unknown Proto
Discards Input/
Output
For packet-oriented interfaces, the number of packets received
through the interface which were discarded because of an unknown or
unsupported protocol. For character-oriented or fixed-length inter-
faces 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. For
ATM, this field displays cells discarded on an invalid vpi/vci.
Unknown proto discards do not show up in the packet counts.
