Description
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.
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 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 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.
The total number of dropped packets including those that were aborted.
The total number of frames that could not be transmitted after multiple attempts
because they encountered collisions.
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.
The number of frames discarded when a lookup in the multicast tree for a VLAN occurs
while that tree is being modified.
The number of frames discarded that are destined to an IEEE 802.1 reserved address
and are not supported by the system.
