Flow control
Activates/deactivates the flow control on the port.
Possible values:

marked (default setting)
The Flow control on the port is active.
The sending and evaluating of pause packets (full-duplex operation) or collisions (half-duplex
operation) is activated on the port.

To enable the flow control in the device, also activate the
Flow control
function in the
Switching > Global
dialog.

Activate the flow control also on the port of the device that is connected to this port.
On an uplink port, activating the flow control can possibly cause undesired sending breaks in
the higher-level network segment (“wandering backpressure”).

unmarked
The Flow control on the port is inactive.
If you are using a redundancy function, then you deactivate the flow control on the participating
ports. If the flow control and the redundancy function are active at the same time, it is possible that
the redundancy function operates differently than intended.
Send trap (Link up/down)
Activates/deactivates the sending of SNMP traps when the device detects changes in the link up/
down status for this port.
Possible values:

marked (default setting)
The sending of SNMP traps is active.
When the device detects a link up/down status change, the device sends an SNMP trap.

unmarked
The sending of SNMP traps is inactive.
The prerequisite for sending SNMP traps is that you enable the function in the
Diagnostics > Status
Configuration > Alarms (Traps)
dialog and specify at least 1 trap destination.
Signal
Activates/deactivates the port LED flashing. This function lets you identify the port in the field.
Possible values:

marked
The flashing of the port LED is active.
The port LED flashes until you disable the function again.

unmarked (default setting)
The flashing of the port LED is inactive.
Link monitoring
Activates/deactivates the
Link monitoring
function on the interface.
Use the
Link monitoring
function for end devices that do not support Far End Fault Indication (FEFI)
on optical links.
