Parameter Default Description
Flow Control
on all ports
Disabled See “Flow Control” in this table.
Type Shows port type as:
10/100TX: 10BASE-T / 100BASE-TX
100FX: 100BASE-FX
1000SX: 1000BASE-SX
1000LX: 1000BASE-LX
Admin Enabled Allows you to disable a port due to abnormal behavior (e.g., excessive
collisions), and then re-enable it after the problem has been resolved.
You may also disable a port for security reasons.
Flow Control Disabled Used to enable or disable 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. IEEE 802.3x flow
control is used for full duplex. Note that flow control should not be used
if a port is connected to a hub.
Speed and Duplex Auto Indicates current port speed and duplex mode.
Note that autonegotiation is not available for the 100BASE-FX ports.
Port Type Speed Duplex Mode Flow Control
100BASE-FX 100M full duplex auto
1000BASE-SX 1000M auto auto
1000BASE-LX 1000M auto auto
The
1000BASE-SX and 1000BASE-LX ports are fixed at 1000 Mbps
but autonegotiate duplex mode. The
100BASE-FX
module is fixed at
the indicated speed and duplex mode. All media types can
autonegotiate flow control.
