Editing of port parameters can be done in the Port Parameters section
or in the Active/Configured Port Settings table
The description of the fields appearing in Port Parameters section and Active/Configured Port Settings table are as follows:
Rate Limiter (Flow Control)
Flow control is a mechanism which acts as an overload protection for the device. During periods of heavy traffic, it holds off additional traffic from the network. 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.

Broadcast Storm
The device allows you to limit the traffic on the ports in order to help provide reliable operation even with a large traffic volume. If the traffic on a port exceeds the traffic value entered, the device discards the excess traffic on this port. The rate limiter function operates exclusively on layer 2, and is used to limit the effects of storms of data packets that flood the device. The Broadcast Threshold specifies the threshold value for broadcast traffic on this port.

PoE User Set Limit
This feature allows to set a limit for the power that is provided at a port. This value overwrites the value which stands for the negotiated PoE class. If the default value 0 ("-") is set, the limit given by the PoE class continues to be relevant/applicable for how much power is available at the port. The values 1 to 13 can only be set, if all PoE classes are allowed, i. e. PoE Allowed Classes must be set to its default value 0, 1, 2, 3, 4. If any value from 1 to 13 is set, the available power on this port is limited to this value in Watt. When setting this value, the user has to regard, that the provided power for the connected PoE device is sufficient at any time during operation. Otherwise regular and proper functioning of the connected PoE device can not be assured.
This feature is supported by devices as of serial number 9421510010002 only. Older devices will indicate in the log file, that this parameter could not be set. If you are interested in this feature, please contact our support.
