9.2.1.5.1. Instance attributes
Instance attribute “Interface Speed”
The attribute reveals the currently used speed in the
interface. The speed is announced as an integer number,
with the unit Mbps, e.g. 0, 10, 100 etc. The value 0 indicates
that the interface speed is indeterminate.
Instance attribute “Interface Flags”
The attribute contains status and configuration information
about the physical interface.
Table 103. Interface flag bit descriptions
Bit(s)
Called
Definition
0
Link Status
One, if link is active
1
Half/Full Duplex
One, if full duplex
2-4
Negotiation Status
Value
Definition
0
Auto-negotiation in progress
1
Auto-negotiation and speed detection failed. Using default values for speed and duplex.
2
Auto-negotiation failed but detected speed. Duplex was defaulted.
3
Successfully negotiated speed and duplex.
4
Auto-negotiation not attempted. Forced speed and duplex.
5
Manual Setting Requires Reset
0 indicates the interface can automatically activate changes to link parameters (auto-negotiate, duplex mode, interface
speed). 1 indicates the device requires a Reset service be issued to its Identity Object in order for the changes to take
effect.
6
Local Hardware Fault
0 indicates the interface detects no local hardware fault; 1 indicates a local hardware fault is detected.
7-31
Reserved
Always zero
Instance attribute “Physical Address”
The attribute reveals the MAC layer address of the
physical interface.
Instance attribute “Interface Counters”
The attribute is a collection of counters related to the
Ethernet physical interface. The OPTE9 option board has
only single MAC address and therefore implements only
single set of counter values. Only packets sent or received
by the device itself are counted.
Table 104. Interface counters
Field name
Data type
Description
In octets
UDINT
The number of octets received on the interface (including framing characters).
In unicast packets
UDINT
The number of unicast packets received on the interface.
In nonunicast packets
UDINT
The number of non-unicast packets received on the interface.
In discards
UDINT
Inbound packets received on the interface but which were discarded.
In errors
UDINT
Inbound packets received on the interface but which contained errors (excluding Discards).
In unknown protocols
UDINT
Inbound packets received on the interface which belonged to unknown protocols.
Out octets
UDINT
The number of octets sent on the interface (including framing characters).
Out unicast packets
UDINT
The number of unicast packets requested to be transmitted on the interface, including those that were discarded or
not sent.
Out nonunicast packets
UDINT
The number of non-unicast packets requested to be transmitted on the interface, including those that were discarded
or not sent.
Out discards
UDINT
Outbound packets which were discarded.
Out errors
UDINT
Outbound packets which contained errors (excluding Discards).
