◆ Flow Control – Flow control can eliminate frame loss by “blocking” traffic from end
stations or segments connected directly to the switch when its buffers fill. When enabled,
back pressure is used for half- duplex operation and IEEE 802.3-2005 (formally IEEE
802.3x) for full- duplex operation. (Default: Disabled)
When auto-negotiation is used, this parameter indicates the flow control capability
advertised to the link partner. When the speed and duplex mode are manually set, the
Current Rx field indicates whether pause frames are obeyed by this port, and the Current
Tx field indicates if pause frames are transmitted from this port.
Avoid using flow control on a port connected to a hub unless it is actually required to solve
a problem. Otherwise back pressure jamming signals may degrade overall performance
for the segment attached to the hub.
◆ Maximum Frame Size – Sets the maximum transfer unit for traffic crossing the switch.
Packets exceeding the maximum frame size are dropped. (Range: 9600-1518 bytes;
Default: 9600 bytes)
◆ Excessive Collision Mode – Sets the response to take when excessive transmit
collisions are detected on a port.
■ Discard - Discards a frame after 16 collisions (default).
■ Restart - Restarts the backoff algorithm after 16 collisions.
◆ Power Control – Adjusts the power provided to ports based on the length of the cable
used to connect to other devices. Only sufficient power is used to maintain connection
requirements.
EEE 802.3 defines the Ethernet standard and subsequent power requirements based on
cable connections operating at 100 meters. Enabling power saving mode can significantly
reduce power used for cable lengths of 20 meters or less, and continue to ensure signal
integrity.
The following options are supported:
■ Disabled – All power savings mechanisms disabled (default).
■ Enabled – Both link up and link down power savings enabled.
■ ActiPHY – Link down power savings enabled
■ PerfectReach – Link up power savings enabled.
