The Spanning Tree Protocol (STP) is a link management protocol. Alcatel implements the IEEE 802.1D
standard for media access control bridges.

Signal Quality Error Test errors (i.e. Heartbeat) during transmission.
This tests the important collision detection electronics of the trans-
ceiver, and lets the Ethernet interface in the computer know that the
collision detection circuits and signal paths are working correctly.
The errors indicate a count of times that the SQE TEST ERROR
message is generated by the PLS sublayer for a particular interface.
The SQE TEST ERROR message is defined in section 7.2.2.2.4 of
ANSI/IEEE 802.3-1985 and its generation is described in section
7.2.4.6 of the same document.
A count of frames for which reception on a particular interface fails
due to an internal MAC sublayer receive error. A frame is only
counted by an instance of this object if it is not counted by the corre-
sponding instance of either the FrameTooLongs property, the
AlignmentErrors property, or the FCSErrors property. The precise
meaning of the count represented by an instance of this object is
implementation-specific. In particular, an instance of this object may
represent a count of receive errors on a particular interface that are
not otherwise counted.
A count of frames for which transmission on a particular interface
fails due to an internal MAC sublayer transmit error. A frame is only
counted by an instance of this object if it is not counted by the corre-
sponding instance of either the LateCollisions property, the
ExcessiveCollisions property, or the CarrierSenseErrors property.
The precise meaning of the count represented by an instance of this
object is implementation-specific. In particular, an instance of this
object may represent a count of transmission errors on a particular
interface that are not otherwise counted.
The Carrier Sense detects the presence of a carrier. The number of
times that the carrier sense condition was lost or never asserted
when attempting to transmit a frame on a particular interface.
A count of frames received on a particular interface that exceed the
maximum permitted frame size. The count represented by an
instance of this object is incremented when the FrameTooLong
status is returned by the MAC layer to the LLC (or other MAC user).
Received frames for which multiple error conditions obtain are,
according to the conventions of IEEE 802.3 Layer Management,
counted exclusively according to the error status presented to the
LLC.
