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.
• Total Received Packets
Not Forwarded
A count of valid frames received which were discarded (i.e. 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.
• Total Packets
Transmitted (Octets)
The total number of octets of data (including those in bad packets) transmitted on
the network (excluding framing bits but including FCS octets). This object can be
used as a reasonable estimate of Ethernet utilization. If greater precision is
desired, the etherStatsPkts and etherStatsOctets objects should be sampled
before and after a common interval.
