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.
