o Configured: enable advertising link partners of flow control
capability. This is only used if Speed Configure of the port is forced
speed, and not used when is set to Auto mode.
There is also an indication of the transmission and reception of flow control
messages. These fields are not configurable, and are automatically enabled or
disabled as follows:
o Flow Control Current Rx: indicates if flow control pause frames are
obeyed at the port. The symbol means that pause frames are
obeyed at that port, and the symbol means that pause frames are
not used at that port, that is, Flow Control Configured Checkbox is
disabled or port is in Auto mode;
o Flow Control Current Tx: indicates if flow control pause frames are
transmitted at the port. The symbol means that pause frames
are transmitted at that port, and the symbol means that pause
frames are not used at that port, that is, Flow Control Configured
Checkbox is disabled or port is in Auto mode
Maximum Frame Size:
This field allows configuring the maximum frame size accepted by the switch,
including the FCS bits, in bytes. Frames with sizes higher than specified in this field
are discarded. Allowed values are from 1518 to 10056.
Excessive Collision Mode:
This field allows configuring switch’s behaviour when there are collisions detected at
a given port. A collision happens when port is operating in half-duplex mode, where
there is the possibility of two hosts sending transmission frames at the same time,
generating collisions at the physical medium. After 16 collisions, Reason Switches
can perform the Excessive Collision Mode. By default, frame is discarded after 16
collisions. Allowed options are:
o Discard: enable the switch to discard the frame after 16 collisions
at the port;
o Restart: enable the switch to restart backoff algorithm after 16
collisions at the port.
After one of the configurations described before is changed, the user may save or
discard the configurations. Refresh button is also available in this web page.
o Save: save configuration at the Running Config;
o Reset: undo changes made locally at the Running Config;
