Description
The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets) and were otherwise well
formed.
The total number of packets received that were without errors.
The number of subnetwork-unicast packets delivered to a higher-layer
protocol.
The total number of good packets received that were directed to a multicast
address. This number does not include packets directed to the broadcast
address.
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 nonintegral number of octets (Alignment Error). Note
that this definition of jabber is different from 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
with ERROR CRC (excluding framing bits but including FCS octets).
The total number of packets received that were less than 64 octets in length
with GOOD CRC (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 nonintegral 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 (for example filtered)
by the forwarding process.
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.
