Packets Received
Successfully
•
Total Packets Received Without Error
- The total number of packets received that were without
errors.
•
Unicast Packets Received
- The number of subnetwork-unicast packets delivered to a higher-layer
protocol.
•
Multicast Packets Received
- The total number of good packets received that were directed to a
multicast address. Note that this number does not include packets directed to the broadcast
address.
•
Broadcast Packets Received
- The total number of good packets received that were directed to
the broadcast address. Note that this does not include multicast packets.
Packets Received
with MAC Errors
•
Total
- The total number of inbound packets that contained errors preventing them from being
deliverable to a higher-layer protocol.
•
Jabbers Received
- 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/Undersize Received
- The total number of packets received that were less than 64
octets in length (excluding framing bits but including FCS octets).
•
Alignment Errors
- 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 -
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
- The total number of frames discarded as this port was overloaded with incoming
packets, and could not keep up with the inflow.
Received Packets
Not Forwarded
•
Total
- A count of valid frames received which were discarded (in other words, filtered) by the
forwarding process
•
Local Traffic Frames
- The total number of frames dropped in the forwarding process because the
destination address was located off of this port.
•
802.3x Pause Frames Received
- A count of MAC Control frames received on this interface with
an opcode indicating the PAUSE operation. This counter does not increment when the interface is
operating in half-duplex mode.
•
Unacceptable Frame Type
- The number of frames discarded from this port due to being an
unacceptable frame type.
•
Multicast Tree Viable Discards
- The number of frames discarded when a lookup in the multicast
tree for a VLAN occurs while that tree is being modified.
•
Reserved Address Discards
- The number of frames discarded that are destined to an IEEE 802.1
reserved address and are not supported by the system.
•
Broadcast Storm Recovery
- The number of frames discarded that are destined for
FF:FF:FF:FF:FF:FF
when Broadcast Storm Recovery is enabled.
•
CFI Discards
- The number of frames discarded that have CFI bit set and the addresses in RIF are
in non-canonical format.
•
Upstream Threshold
- The number of frames discarded due to lack of cell descriptors available for
that packet's priority level.
