LevelOne GSW-2600TXM manual Layer 2 Address Table

Parameter	Description
Drop Events	The total number of events in which packets were dropped
	due to lack of resources.
Bytes	Total number of bytes of data received on the network. This
	statistic can be used as a reasonable indication of Ethernet
	utilization.
Frames	The total number of frames (bad, broadcast and multicast)
	received.
Broadcast Frames	The total number of good frames received that were directed
	to the broadcast address. Note that this does not include
	multicast packets.
Multicast Frames	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 Frames	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 Frames	The total number of frames received that were longer than
	1518 octets (excluding framing bits, but including FCS octets)
	and were otherwise well formed.
Fragments	The total number of frames received that were less than 64
	octets in length (excluding framing bits, but including FCS
	octets) and had either an FCS or alignment error.
Jabbers	The total number of frames received that were longer than
	1518 octets (excluding framing bits, but including FCS octets),
	and had either an FCS or alignment error.
Collisions	The best estimate of the total number of collisions on this
	Ethernet segment.
64 Byte Frames	The total number of frames (including bad packets) received
	and transmitted that were 64 octets in length (excluding
	framing bits but including FCS octets).
65-127 Byte Frames	The total number of frames (including bad packets) received
128-255 Byte Frames	and transmitted where the number of octets fall within the
256-511 Byte Frames	specified range (excluding framing bits but including FCS
512-1023 Byte Frames	octets).
1024-1518 Byte Frames
1519-1536 Byte Frames
Note:

Statistics are refreshed every 10 seconds by default (chapter “Configuring the Serial Port”)..
