Forced Interface Speed:
When the auto-negotiate bit is 0 (Bit0 = 0), it indicates the speed at which the interface shall operate.
Speed is specified in megabits per second (Mbps).
Attribute 7, Interface Type
This attribute value indicates the type of physical interface. ELAP MEM-BUS encoder has got an interface of
type 2,
Twisted-pair (10Base-T, 100Base-T, 1000Base-T, etc.).
Attribute 8, Interface State
This attribute value indicates the current operational state of the interface.
= 0 , unknown interface state.
= 1 ,the interface is enabled and ready to send and receive data.
= 2 , the interface is disabled.
= 3 , the interface is testing.
= 4, …, 256 reserved values.
Attribute 9, Administrative State
This attribute value allows administrative setting of the interface state.
= 1 , enable the interface.
= 2 , disable the interface.
Attribute 10, Interface Label
This attribute value is a text string, describing the interface.
Attribute 11, Interface Capability
This attribute value indicates the set of capabilities for the interface. It is a data structure with two main
elements:
Capability Bits and Speed/Duplex Options .
Capability Bits: it is an array of bits, indicating whether the interface supports capabilities such as auto-
negotiation and auto-MDIX.

Bit0

Manual Setting Requires Reset.
It indicates whether or not the device requires a reset to apply changes made to attribute 6;
= 0 , the device automatically applies changes, without any reset operation.

Bit1

Auto-negotiate.
= 1, indicates that the interface supports link auto-negotiation.

Bit2

Auto-MDIX.
= 1, indicates that the interface supports auto-MDIX operation.

Bit3

Manual Speed/Duplex.
= 1, indicates that the interface supports manual setting of speed/duplex via the attribute 6.

Bit4, …, Bit31

Reserved, shall be set to 0.
Speed/Duplex Options: it is an array of speed/duplex pairs that may be set via the attribute 6 (for example,
10 Mbps – Half Duplex, 100 Mbps – Full Duplex, etc.).
