Instance Attribute “Interface Type”
The Ethernet Link Object has an instance attribute named “Interface Type” which has the Attribute
Identifier 07
h
. The attribute indicates the type of the Ethernet interface, i.e. twisted-pair cable, optical fiber,
device-internal etc.
Instance Attribute “Interface State”
The Ethernet Link Object has an instance attribute named “Interface State” which has the Attribute
Identifier 08
h
. The attribute indicates the current state of the Ethernet interface, i.e. operational, disabled
etc.
Instance Attribute “Admin State”
The Ethernet Link Object has an instance attribute named “Admin State” which has the Attribute
Identifier 09
h
. The attribute indicates the ability to use the Ethernet interface for administration e.g.
changing settings.
Vacon 100 drives support this attribute with the value 01
h
(administration enabled). An attempt to
disable the administration (by writing value 02
h
) will result in an error.
Instance Attribute "Interface Label"
The Ethernet Link Object has an instance attribute named "Interface Label" which has the attribute
identifier 0Ah. The attribute contains a vendor-specific, human-readable text string with a maxi-
mum length of 64 characters which describes the interface. The attribute is read-only
Table 19.
Field Field data type Description
Alignment Errors Unsigned32 Frames received that are not an integral number of
octets in length.
FCS Errors Unsigned32 Frames received that do not pass the FCS check.
Single Collisions Unsigned32 Successfully transmitted frames which experi-
enced exactly one collision.
Multiple Collisions Unsigned32 Successfully transmitted frames which experi-
enced more than one collision.
SQE Test Errors Unsigned32 The number of times SQE test error message is
generated.
Deferred Transmissions Unsigned32 Frames for which the first transmission attempt is
delayed because the medium is busy.
Late Collisions Unsigned32 Number of times a collision is detected later than
512 bit-times into the transmission of a packet.
Excessive Collisions Unsigned32 Frames for which transmission fails due to exces-
sive collisions.
MAC Transmit Errors Unsigned32 Frames for which transmission fails due to an
internal MAC sub layer transmit error.
Carrier Sense Errors Unsigned32 Times that the carrier sense condition was lost or
never asserted when attempting to transmit a
frame.
Frame Too Long Unsigned32 Frames received that exceed the maximum per-
mitted frame size.
MAC Receive Errors Unsigned32 Frames for which reception on an interface fails
due to an internal MAC sub layer receive error.
