Description
Total Ethernet packets received.
Discarded received packets because the internal
Received Packet Ring Pool Buffers are empty;
therefore no incoming packets could be processed.
Protocol Type field value in Ethernet header does
not correspond to IP.
No. of discarded received packets due to the
following reasons:
Frames containing a no. of bits not divisible by eight
is received and discarded.
Received frame contains CRC errors in the header.
Received frame is smaller than the minimum
defined for this interface.
Received frame lengths are greater than maximum
defined for this interface.
Discarded frames because a collision occurred
during frame reception. No. of times that a collision
is detected on a particular interface later than 512
bit-times into the transmission of a packet.
Discarded received packets due to the internal
Received Packet Ring Pool are full; therefore no
incoming packets could be processed.
Total Ethernet packets sent.
Discarded outgoing packets due to internal
Transmitted Packet Ring Pool Buffers are full.
Could not process any outgoing packets.
Length of outgoing packets is larger than the
maximum length of this interface.
No. of discarded transmitted packets due to:
No. of transmitting Heartbeat (signal-quality error)
packets lost/errors.
A count of frames for which the first transmission
attempts on a particular interface is delayed
because the medium is busy. The count
represented by an instance of this object does not
include frames involved in collisions.
Discarded transmitted frames because a collision
occurred. No. of times that a collision is detected on
a particular interface later than 512 bit-times into
the transmission of a packet.
A count of frames for which transmission on a
particular interface fails due to excessive collision
