4.2.1.1 State
The port state is the administrative state of this port. The state may be up or down. When
‘UP’, the port is enabled and will generate a Major Alarm if the link is physically down.
When in the ‘DOWN’ state, the port is disabled.
4.2.1.2 Link Status
The Link Status is a display of the current link status. If the link is up, the link status will
show UP and vice versa. Only when the link status is UP are the operating parameters
valid when in auto negotiating mode.
4.2.1.3 Auto Negotiation
The port may be configured to automatically determine the optimal operating parameters
for link speed and duplex. Alternatively, it may be disabled to enable configuration of fixed
operating parameters.
Note, the Auto Negotiating algorithm works optimally with a link partner that also supports
auto negotiation. For operation where one end of a link uses fixed configuration and does
not negotiate, it must be noted that only Speed, 10 or 100M, can be determined, the auto
negotiating node will fall back to use half duplex. 1000M operation requires auto
negotiation to be used.
4.2.1.4 Speed
When in auto negotiating mode, the speed displayed is the highest that will be advertised
to the link partner. In non auto negotiating mode, the speed is manually set by the user.
4.2.1.5 Duplex
When in auto negotiating mode, the duplex displayed is the highest that will be advertised
to the link partner. In non auto negotiating mode, the duplex is manually set by the user.
4.2.1.6 Negotiated
This item displays the actual operating parameters of the link following auto negotiation
and may take the values:
1000/FD
1000Mbps, Full Duplex
100/FD
100Mbps, Full Duplex
100/HD
100Mbps, Half Duplex
10/FD
10Mbps, Full Duplex
10/HD
10Mbps, Half Duplex
