Expansion Slot 1 - 1-Port 1000Base-SX-SC
Parameter Default Description
Admin Status Enable 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.
Duplex Mode Auto-
Negotiation Used to set the port of full or half
duplex mode, or auto-negotiation.
The default for gigabit ports is auto-
negotiation. However, note that
auto-negotiation is not available for
the 100Mbps fiber ports.
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. Back pressure is
used for half duplex and IEEE 802.3x
for full duplex. Note that flow
control should not be used if a port
is connected to hub.
