4. The following fields are displayed:
Port— Indicates the port number.
Type— Specifies the if the port is fiber, indicated by 1000-FX, or
copper, indicated by 100-FX.
Status— Indicates if the port is enabled or disabled. The default
setting is “Enabled.” Disabling ports turns off their receivers and
transmitters so that they cannot forward traffic.
Link— Indicates the port has successfully connected to a port on
another switch or unit.
Negotiation— Indicates Autonegotiation. By default,
Autonegotiation is enabled.
Speed— Specifies the speed of the port. The default setting is
“1000-FX” for 1000Mbps. The other possible options are “10” for
10Mbps and “100” for 100Mbps.
Duplex— Indicates the duplex mode of the twisted pair ports or
Auto Negotiation. The three settings are half, full, and Auto
Negotiation.
Polarity— Indicates the port’s wiring configuration is MDI (medium
dependent interface) or MDI-X (medium dependent interface
crossover). This setting only applies to a twisted pair port that is
operating at 10 or 100 Mbps.
Note
You can enable or disable backpressure on ports where you
disabled Auto-Negotiation and set the speeds and duplex modes
manually to 10 or 100 Mbps in half-duplex mode.
Back Pressure— Indicates if back pressure is enabled or disabled
on a port. Backpressure is used by ports during periods of packet
congestion to temporarily stop their network counterparts from
transmitting more packets. This prevents a buffer overrun and the
subsequent loss and retransmission of network packets. A port
initiates backpressure by transmitting on the shared link to cause a
data collision, which causes its link partner to cease transmission.
The default setting is “Disabled.”
Back Pressure Limit— Indicates the threshold level for back
pressure on a port. Specifies the number of cells for back
pressure. The default value is 7935 cells.
Flow Control— Indicates if flow control (send and receive) is
enabled or disabled on a port. When flow control is enabled, a port
sends pause packets when it reaches the point of packet
congestion. Also, the port stops transmitting packets when it
receives pause packets from its local or remote counterpart. When
flow control is disabled, the port sends pause packet regardless of
