Description
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.
The total number of good packets received that were directed to the
broadcast address. Note that this does not include multicast packets.
The total number of inbound packets that contained errors preventing
them from being deliverable to a higher-layer protocol
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.
The total number of packets received that were less than 64 octets in
length (excluding framing bits but including FCS octets).
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.
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
The total number of frames discarded as this port was overloaded
with incoming packets, and could not keep up with the inflow
A count of valid frames received which were discarded (i.e. filtered)
by the forwarding process
The total number of frames dropped in the forwarding process
because the destination address was located off of this port.
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.
The number of frames discarded from this port due to being an
unacceptable frame type.
An entry in this field does not necessarily indicate that the interface is
receiving error packets. This field is incremented when packets are
dropped due to an ACL filtering them out, when tagged packets are
received on an untagged port, or when untagged packets are received
on a tagged port.
This field does not increment when the following packets are received:
CRC error packets, non-IP packets, giants.
The number of frames discarded when a lookup in the multicast tree
for a VLAN occurs while that tree is being modified.
