Expansion Port Configuration
Use the Expansion Port Configuration menus to configure any module port on the
switch.
Parameter Default Description
Admin Status Enable Allows you to disable a port due to abnormal behavior, and then
re-enable it after the problem has been resolved. You may also
disable a port for security reasons.
Speed/Duplex Status Auto-
Negotiation
Used to set the current port speed, duplex mode, flow control, and
autonegotiation.
Port Type
Speed Duplex Mode Flow Control
100BASE-FX 100M full duplex auto
1000BASE-SX 1000M auto auto
1000BASE-LX 1000M auto auto
1000BASE-T 10/1001000M auto auto
The 1000BASE-SX and 1000BASE-LX ports are fixed at
1000 Mbps but autonegotiate duplex mode. The 1000BASE-T
autonegotiates duplex mode and autonegotiates speed to
10/100/1000 Mbps. The 100BASE-FX module is fixed at the
indicated speed and duplex mode. All media types can
autonegotiate flow control.
Flow Control Status 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
a hub.
