Configuring Port Connections
– 64 –
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 – 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.
IEEE 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.
