Chapter 7 – Configuration
It is possible to limit electrical port speed when operating in Auto mode using the Adv speed configuration. That is, if both end
nodes (e. g., switch and IED equipment) operates in Auto mode, then the switch can limit port speed enabling the advertisement
given to IED. If only 10 Mbps Advertisement is selected, then port speed Auto negotiation will select 10 Mbps speed, and the
same behaviour will occur for 100 Mbps and 1 Gbps speeds.
REASON SWITCHES-TM-EN-3
1000-FX: enable optical port speed to 1 Gbps in full-duplex mode;
o
1000-FX_AMS: enable AMS mode at the port. Optical ports will be
o
enabled to 1 Gbps in full-duplex mode and electrical ports will be
enabled as Auto mode.

Advertise Duplex (Adv Duplex):
This field allows configuring link partner advertisement of communication mode
when Speed Configure is defined as Auto. By default, all full-duplex mode ports
detected will advertise its partners of the duplex capacity. It is possible to configure
these fields as follows:

Fdx checkbox: enable advertising link partners at the port that full-duplex is
supported at that port if checked;

Hdx checkbox: enable advertising link partners at the port that half-duplex
is supported at that port if checked.

Advertise Speed (Adv speed):
This field allows configuring link partner advertisement of communication speed
when Speed Configure is defined as Auto. By default, all port capacity (10/100/1000
Mbps) will advertise its partners of all capacity (up to 1 Gbps). It is possible to
configure these fields as follows:
Speed 10 checkbox: enable advertising link partners at the port
o
that 10 Mbps speed is supported at that port if checked;
Speed 100 checkbox: enable advertising link partners at the port
o
that 100 Mbps speed is supported at that port if checked;
Speed 1000 checkbox: enable advertising link partners at the port
o
that 1 Gbps speed is supported at that port if checked;

Flow Control:
This field allows configuring link partner advertisement of communication flow
control when Speed Configure is defined as Auto. By default, all ports detected will
advertise its partners of the flow control capacity based on the last Auto-negotiation
process. It is possible to configure these fields as follows:
