Table 8 Status: Port Details (continued)

LABEL	DESCRIPTION
Control	This field shows the number of control packets received (including those
	with CRC error) but it does not include the 802.3x Pause packets.

TX Collision
The following fields display information on collisions while transmitting.

Single	This is a count of successfully transmitted packets for which transmission is
	inhibited by exactly one collision.

Multiple	This is a count of successfully transmitted packets for which transmission
	was inhibited by more than one collision.

Excessiv	This is a count of packets for which transmission failed due to excessive
e	collisions. Excessive collision is defined as the number of maximum
	collisions before the retransmission count is reset.

Late	This is the number of times a late collision is detected, that is, after 512
	bits of the packets have already been transmitted.

Error Packet	The following fields display detailed information about packets received
	that were in error.

RX CRC	This field shows the number of packets received with CRC (Cyclic
	Redundant Check) error(s).

Length	This field shows the number of packets received with a length that was out
	of range.

Runt	This field shows the number of packets received that were too short
	(shorter than 64 octets), including the ones with CRC errors.

Distribution

64	This field shows the number of packets (including bad packets) received
	that were 64 octets in length.

65-127	This field shows the number of packets (including bad packets) received
	that were between 65 and 127 octets in length.

128-255	This field shows the number of packets (including bad packets) received
	that were between 128 and 255 octets in length.

256-511	This field shows the number of packets (including bad packets) received
	that were between 256 and 511 octets in length.

512-	This field shows the number of packets (including bad packets) received
1023	that were between 512 and 1023 octets in length.

1024-	This field shows the number of packets (including bad packets) received
1518	that were between 1024 and 1518 octets in length.

Giant	This field shows the number of packets (including bad packets) received
	that were between 1519 octets in length and the maximum frame size.
	The maximum frame size varies depending on your switch model. See
	Chapter 47 on page 419.
