This dialog allows you to specify the following settings:
Change the aging time of the address table (forwarding database)
Enable the flow control in the device
If a large number of data packets are received in the priority queue of a port
at the same time, this can cause the port memory to overflow. This happens,
for example, when the device receives data on a Gigabit port and forwards it
to a port with a lower bandwidth. The device discards surplus data packets.
The flow control mechanism described in standard IEEE 802.3 ensures that
no data packets are lost due to a port memory overflowing. Shortly before a
port memory is completely full, the device signals to the connected devices
that it is not accepting any more data packets from them.
In full-duplex mode, the device sends a pause data packet.
In half-duplex mode, the device simulates a collision.
Then the connected devices do not send any more data packets for as long
as the signaling takes. On uplink ports, this can possibly cause undesired
sending breaks in the higher-level network segment (“wandering
backpressure”).
