Autonegotiation/Ethernet link parameters
Ethernet link autonegotiation is supported by default!
Setting: autonegotiation "on"
When negotiating the link parameters, ARGUS informs the remote station that the following
is supported (these settings are fixed and cannot be configured):
-
10, 100 or 1000 Mbit/s
-
Half or full duplex
-
Flow control on/off (for on: symmetric and asymmetric pause)
Manually configuring the Ethernet link parameters
Setting: autonegotiation "off"
When autonegotiation is deactivated, the speed, duplex and flow control ("pause" method)
can be configured in the profile (see page 72).
-
10, 100 or 1000 Mbit/s, default:
100 Mbit/s
-
Half or full duplex, default:
full
-
Flow control on/off ("Flow control off" is only useful in full duplex mode)
Default:
on
Unilateral autonegotiation
When a terminal device with autonegotiation "on" encounters a device without
autonegotiation, no information is transmitted by the remote station. Even without
autonegotiation, the speed is determined using the pulse method/idle pattern (parallel
detection). In this case, the terminal device with autodetection generally drops back to half
duplex (duplex mismatch possible), which can result in a duplex mode conflict with "poor
throughput".

Switches on or off
When autonegotiation is switched on, network cards can automatically
detect the correct transmission speed and duplex method of the Ethernet
port to which they are connected and configure themselves accordingly. In
Ethernet, autonegotiation is based on layer 1 of the OSI model (according
to IEEE standard 802.3u).
Default:
on
