▫
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
▫
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.
▫
VLAN Membership Mismatch - The number of frames discarded on this port due to ingress
filtering.
▫
Total - 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.
▫
VLAN Viable Discards - The number of frames discarded on this port when a lookup on a
particular VLAN occurs while that entry in the VLAN table is being modified, or if the VLAN has not
been configured.
▫
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
