Field	Description

128-255 bytes	Received column: Indicates the total number of 128-byte to 255-byte packets
	received on this port.
	Transmitted column: Indicates the total number of 128-byte to 255-byte packets
	transmitted successfully on this port.

256-511 bytes	Received column: Indicates the total number of 256-byte to 511-byte packets
	received on this port.
	Transmitted column: Indicates the total number of 256-byte to 511-byte packets
	transmitted successfully on this port.

512-1023 bytes	Received column: Indicates the total number of 512-byte to 1023-byte packets
	received on this port.
	Transmitted column: Indicates the total number of 512-byte to 1023-byte packets
	transmitted successfully on this port.

1024-1518 bytes	Received column: Indicates the total number of 1024-byte to 1518-byte packets
	received on this port.
	Transmitted column: Indicates the total number of 1024-byte to 1518-byte packets
	transmitted successfully on this port.

Frame Errors	Indicates the total number of valid-size packets that were received but discarded
	because of CRC errors and improper framing.

Undersized Packets	Indicates the total number of packets received on this port with fewer than 64 bytes
	and with proper CRC and framing (also known as short frames or runts).

Oversized Packets	Indicates the total number of packets received on this port with more than 1518
	bytes and with proper CRC and framing (also known as oversized frames).

Filtered Packets	Indicates the number of packets filtered (not forwarded) by this port.

Flooded Packets	Indicates the total number of packets flooded (forwarded) through this port
	because the destination address was not in the address database.

FCS Errors	Indicates the total number of valid-size packets that were received with proper
	framing but discarded because of cyclic redundancy check (CRC) errors.

Collisions	Indicates the total number of collisions detected on this port.

Single Collisions	Indicates the total number of packets that were transmitted successfully on this
	port after a single collision.

Multiple Collisions	Indicates the total number of packets that were transmitted successfully on this
	port after more than one collision.

Excessive Collisions	Indicates the total number of packets lost on this port due to excessive collisions.

Deferred Packets	Indicates the total number of frames that were delayed on the first transmission
	attempt, but never incurred a collision.

Late Collisions	Indicates the total number of packet collisions that occurred after a total length of
	time that exceeded 512 bit-times of packet transmission.
