Table 4 Received Ethernet Frames
Frame Type Description
Received Good Frames Total number of frames received by the switch since the last reset.
Filtered Frames Frames received by the switch but not forwarded because the
destination is within the same LAN segment; therefore, the frame
was already seen by all nodes on the segment.
Broadcasts Frames received by the switch destined for all nodes on the network,
excluding multicast frames.
Multicasts Frames received by the switch destined for multiple but specific
addresses, excluding broadcast frames.
CRC Errors Frames with a cyclic redundancy check (CRC) error but with the
proper length (64-1518 bytes).
Alignment Errors Frames with a non-integral number of bytes, that is, frame length in
bits are not evenly divisible by 8, but with the proper length (64-1518
bytes).
Undersized Frames Frames less than the minimum specified by IEEE 802.3 (64 bytes
including the CRC); also called runts.
Fragments Undersized frames, frames with alignment errors, and frames with
FCS errors (CRC errors).
Long Frames Frames exceeding the maximum specified by IEEE 802.3 (1518 bytes
including the CRC).
