RFC 1284 Ethernet-Like Interface Statistics

RFC 1284 Ethernet-Like Interface Statistics

Following are descriptions of the Ethernet-like statistics ﬁelds in the lanadmin(1M) command display.

Field	Description
Index	A value that uniquely identiﬁes an interface to an
	802.3 medium.
Alignment Errors	A count of frames received on a particular interface
	that are not an integral number of octets in length
	and do not pass the FCS check.
FCS Errors	A count of frames received on a particular interface
	that are not an integral number of octets in length
	and do not pass the FCS check.
Single Collision Frames	A count of successfully transmitted frames on a
	particular interface for which transmission is
	inhibited by exactly one collision.
Multiple Collision Frames	A count of successfully transmitted frames on a
	particular interface for which transmission is
	inhibited by more than one collision.
Deferred Transmissions	A count of frames for which the ﬁrst transmission
	attempt on a particular interface is delayed because
	the medium is busy. The count represented by an
	instance of this object does not include frames
	involved in collisions.
Late Collisions	The number of times that a collision is detected on a
	particular interface later than 512 bit-times into the
	transmission of a packet.
Excessive Collisions	A couple of frames for which transmission on a
	particular interface fails due to excessive collisions or
	packets dropped.
Internal MAC Transmit Errors	A count of frames for which transmission on a
	particular interface fails due to an internal MAC
	sublayer transmit error.
Carrier Sense Errors	The number of times that the carrier sense condition
	was lost or never asserted when attempting to
	transmit a frame on a particular interface.
Frames Too Long	A count of frames received on a particular interface
	that exceed the maximum permitted frame size.
Internal MAC Receive Errors	A count of frames for which reception on a particular
	interface fails due to an internal MAC sublayer
	receive error.
