• Received Nuknown
Unicast Packets
The number of packets received via the interface which were discarded because
of an unknown or unsupported protocol.
• Received Discards
Packets
The number of inbound packets which were chosen to be discarded even though
no errors had been detected to prevent their being deliverable to a higher-layer
protocol. One possible reason for discarding such a packet could be to free up
buffer space.
• Transmit Octets The total number of octets transmitted out of the interface, including framing
characters.
• Transmit Unicast
Packets
The total number of packets that higher-level protocols requested be transmitted
to a subnetwork-unicast address, including those that were discarded or not sent.
• Transmit Nuknown
Unicast Packets
The total number of packets that higher-level protocols requested betransmitted
to a subnetwork-unicast address, including those that were discarded or not sent.
• Transmit Discards
Packets
The number of inbound packets which were chosen to be discarded even though
no errors had been detected to prevent their being deliverable to ahigher-layer
protocol. One possible reason for discarding such a packet could be to free up
buffer space.
• Received Multicast
Packets
The number of packets, delivered by this sub-layer to a higher (sub-)layer, which
were addressed to a multicast address at this sub-layer.
• Received Broadcast
Packets
The number of packets, delivered by this sub-layer to a higher (sub-)layer, which
were addressed to a broadcast address at this sub-layer.
• Transmit Multicast
Packets
The total number of packets that higher-level protocols requested betransmitted,
and which were addressed to a multicast address at this sub-layer, including
those that were discarded or not sent.
• Transmit Broadcast
Packets
The total number of packets that higher-level protocols requested be transmitted,
and which were addressed to a broadcast address at this sub-layer, including
those that were discarded or not sent.
Ethernet-Link Counters:
Object Description
• Alignment Errors The number of alignment errors (missynchronized data packets).
• FCS Errors A count of frames received on a particular interface that are an integral number of
octets in length but do not pass the FCS check. This count does not include
frames received with frame-too-long or frame-too-short error.
• Single Collision
Frames
The number of successfully transmitted frames for which transmission isinhibited
by exactly one collision.
• Multiple Collision
Frames
A count of successfully transmitted frames for which transmission is inhibited by
more than one collision.
• Deferred
A count of frames for which the first transmission attempt on a particularinterface
