Packets received > 1024
Octets
The total number of packets received that were in excess of 1024 octets
(excluding framing bits but including FCS octets) and were otherwise well
formed.
Total Packets Received
Without Errors
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. 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. This does not include multicast packets.
Total Packets Received with
MAC Errors
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 included 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). 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.
Fragments Received The total number of packets received that were less than 64 octets in length with
ERROR CRC (excluding framing bits but including FCS octets).
Undersize Received The total number of packets received that were less than 64 octets in length with
GOOD CRC (excluding framing bits but including FCS octets).
Alignment Errors The total number of packets received with a length (excluding framing bits, but
including FCS octets) between 64 and 1518 octets, inclusive, but included a bad
frame check sequence (FCS) with a nonintegral number of octets.
Rx FCS Errors The total number of packets received with a length (excluding framing bits, but
including FCS octets) between 64 and 1518 octets, inclusive, but included a bad
frame check sequence (FCS) with an integral number of octets.
Overruns The total number of frames discarded because this port was overloaded with
incoming packets, and could not keep up with the inflow.
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.
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.
Total Packets Transmitted
Successfully
The number of frames that were transmitted by this port to its segment.
