69
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
Transmissions
A count of frames for which the first transmission attempt on a particularinterface
is delayed because the medium was busy.
• Late Collision
The number of times that a collision is detected later than 512 bit-times into the
transmission of a packet.
• Excessive Collision
A count of frames for which transmission on a particular interface fails due to
excessive collisions. This counter does not increment when the interface is
operating in full-duplex mode.
• Frame Too Longs
A count of frames received on a particular interface that exceed the maximum
permitted frame size.
• Symbol Errors
The number of received and transmitted symbol errors.
• Control In Unknow
Opcodes
The number of received control unknown opcodes
• In Pause Frames
The number of received pause frames
• Out Pause Frames
The number of transmitted pause frames
RMON Counters:
Object Description
• Drop Events
The total number of events in which packets were dropped due to lack of
resources.
• Octets
The total number of octets received and transmitted on the interface, including
framing characters.
• Packets
The total number of packets received and transmitted on the interface.
• Broadcast Packets
The total number of good frames received that were directed to the broadcast
address. Note that this does not include multicast packets.
• Multicast Packets
The total number of good frames received that were directed to this multicast
address.
• CRC / Alignment
Errors
The number of CRC/alignment errors (FCS or alignment errors).
• Undersize Packets
The total number of frames received that were less than 64 octets long(excluding
framing bits, but including FCS octets) and were otherwise well formed.
• Oversize Packets
The total number of frames received that were longer than 1518 octets(excluding
framing bits, but including FCS octets) and were otherwise well formed.
