Internal MAC Receive
Errors
See the number of frames for which reception failed due to an
internal MAC sublayer receive error.
RMON Statistics:
Drop Events See the total number of times that the RMON agent was forced to
discard frames due to lack of available switch resources. This
does not display the number of frames dropped, only the number
of times the RMON agent was forced to discard frames.
Total Octets See the total number of octets (bytes) of data, including those in
bad frames, received on this interface.
Total Packets See the total number of packets (including bad frames, broadcast
frames, and multicast frames) received on this interface.
Broadcast Frames See the total number of good frames that were directed to the
broadcast address. This value does not include multicast frames.
Muticast Frames See the total number of good frames that were directed to the
multicast address. This value does not include broadcast frames.
CRC/Alignment Errors See the number of frames with bad Cyclic Redundancy Checks
(CRC) received from the network. The CRC is a 4-byte field in
the data frame that ensures that the data received is the same as
the data that was originally sent.
Undersize Frames See the number of frames received containing less than the
minimum Ethernet frame size of 64 bytes (not including the
preamble) but having a valid CRC.
Oversize Frames See the number of frames received that exceeded 1516 data bytes
(not including the preamble) but had a valid CRC.
Fragments See the number of received frames that are not the minimum
number of bytes in length, or received frames that had a bad or
missing Frame Check Sequence (FCS), were less than 64 bytes in
length (excluding framing bits, but including FCS bytes) and had
an invalid CRC. It is normal for this value to increment since
fragments are a normal result of collisions in a half-duplex
network.
