Negotiation
Status
Indicates the status of link auto-negotiation:
0 = Auto-negotiation in progress.
1 = Auto-negotiation and speed detection failed. Using default val-
ues for speed and duplex. Default values are product-dependent;
recommended defaults are 10 Mbps and half duplex.
2 = Auto negotiation failed but detected speed. Duplex was defaul-
ted. Default value is product-dependent; recommended default is
half duplex.
3 = Successfully negotiated speed and duplex.
4 = Auto-negotiation not attempted. Forced speed and duplex.
5
Manual Setting
Requires Reset
Indicates whether or not the device requires a reset to apply
changes made to the Interface Control attribute (#6):
0 = the device automatically applies changes made to the Inter-
face Control attribute (#6) and, therefore, does not require a
reset in order for changes to take effect. This is the value this bit
shall have when the Interface Control attribute (#6) is not imple-
mented.
1 = the device does not automatically apply changes made to the
Interface Control attribute (#6) and, therefore, will require a
reset in order for changes to take effect.
6
Local Hardware
Fault
0 = the interface detects no local hardware fault;
1 = a local hardware fault is detected. The meaning of this is
product-specific. Examples are an AUI/MII interface detects no
transceiver attached or a radio modem detects no antennae
attached. In contrast to the soft, possible self-correcting nature of
the Link Status being inactive, this is assumed a hard-fault requir-
ing user intervention.

Description
0
Auto-negotiate
Auto-negotiation is enabled or disabled:
0 = 802.3 link auto-negotiation is disabled;
1 = auto-negotiation is enabled.
If auto-negotiation is disabled, then the device shall use the set-
tings indicated by the Forced Duplex Mode and Forced Interface
Speed bits.
1
Forced Duplex
Mode
If the Auto-negotiate bit is 0, the Forced Duplex Mode bit indicates
whether the interface shall operate in full or half duplex mode:
0 = half duplex;
1 = full duplex.
Interfaces not supporting the requested duplex shall return a GRC
hex 0x09 (Invalid Attribute Value).
If auto-negotiation is enabled, attempting to set the Forced
Duplex Mode bits shall result in a GRC hex 0x0C (Object State Con-
flict).
2-15
Reserved
Set to zero.
