duplex.
• Mirror Port Configuration - Sets the source and target ports for mir-
roring.
• Port Trunking Configuration - Specifies ports to group into aggregate
trunks.

Port Configuration
The Port Configuration screen, shown in Figure 6-20, lets you display or set
communication parameters for any port on the Switch, including adminis-
trative status, auto-negotiation, default communication speed and duplex
mode, as well as flow control in use.
• Port (#) - Number of the port.
• Link Status - Indicates if the port has a valid connection to an
external device.
• Admin Status - Allows you to enable or disable administrative rights per
port.
• Auto Negotiate - Enables or disables auto-negotiation for port speed,
duplex mode, and flow control.
• Default Type - If auto-negotiation is disabled, the port will be set to the
indicated speed and duplex mode.
• Current Type - Indicates the current speed and duplex mode of each port.
Port Configuration
• Flow Control - Used to enable or disable flow control under the "Config"
heading. Flow control can eliminate frame loss by "blocking" traffic from
end stations or segments connected directly to the Switch when its buffers
fill. When enabled, back pressure is used for half duplex and IEEE 802.3x
for full duplex.
Note: Flow control should not be used (set to OFF under "Status") if a port
is connected to a hub.
