Parameter Description
Multicast Packets Displays the total number of good packets received that were directed to a multi-
Received cast address. Note that this number does not include packets directed to the broad-
cast address.
Broadcast Packets Displays the total number of good packets received that were directed to the broad-
Received cast address. Note that this does not include multicast packets.
Received Packets Displays the number of inbound packets which were chosen to be discarded even
Discarded 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.
Total Packets Displays the total number of inbound packets that contained errors preventing them
Received with MAC from being deliverable to a higher-layer protocol.
Errors
Jabbers Received Displays the total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets), and had either a bad Frame
Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad
FCS with a non-integral number of octets (Alignment Error). Note that this definition
of jabber is different than the definition in IEEE-802.3 section 8.2.1.5 (10BASE5)
and section 10.3.1.4 (10BASE2). These documents define jabber as the condition
where any packet exceeds 20 ms. The allowed range to detect jabber is between
20 ms and 150 ms.
Fragments Received Displays the total number of packets received that were less than 64 octets in
length with ERROR CRC(excluding framing bits but including FCS octets).
Undersize Received Displays the total number of packets received that were less than 64 octets in
length with GOOD CRC(excluding framing bits but including FCS octets).
Alignment Errors Displays the total number of packets received that had a length (excluding framing
bits, but including FCS octets) of between 64 and 1518 octets, inclusive, but had a
bad Frame Check Sequence (FCS) with a non- integral number of octets.
Rx FCS Errors Displays the total number of packets received that had a length (excluding framing
bits, but including FCS octets) of between 64 and 1518 octets, inclusive, but had a
bad Frame Check Sequence (FCS) with an integral number of octets.
Overruns Displays the total number of frames discarded as this port was overloaded with
incoming packets, and could not keep up with the inflow.
Total Received Pack- Displays the count of valid frames received which were discarded (i.e. filtered) by
ets Not Forwarded the forwarding process.
802.3x Pause Displays the count of MAC Control frames received on this interface with an
Frames Received opcode indicating the PAUSE operation. This counter does not increment when the
interface is operating in half- duplex mode.
Unacceptable Frame Displays the number of frames discarded from this port due to being an unaccept-
Type able frame type.
