Chapter 3: Port Configuration

Mode -This parameter i Indicates the speed and duplex mode
settings for the port. You can use this parameter to set the speed
and duplex mode of a port. The possible settings are:
Ignore -This parameter i Indicates that the All setting does not
apply to the Mode field. In other words, each port is set
individually.
Auto -This parameter i Indicates the port is using Auto-
Negotiation to set the operating speed and duplex mode. The
actual operating speed and duplex mode of the port are
displayed in parentheses (for example, “1000F” for 1000 Mbps
full duplex mode) after a port establishes a link with an end
node.
Auto (1000F) -This parameter i Indicates the port is configured
for 1000Mbps operation in Auto-Negotiation mode.
1000/Full -This parameter i Indicates the port is configured for
1000Mbps operation in full-duplex mode.
100/Full -This parameter i Indicates the port is configured for
100Mbps operation in full-duplex mode.
10/Full -This parameter i Indicates the port is configured for
10Mbps operation in full-duplex mode.
1000/Half -This parameter i Indicates the port is configured for
1000Mbps operation in half-duplex mode.
100/Half -This parameter i Indicates the port is configured for
100Mbps operation in half-duplex mode.
10/Half -This parameter i Indicates the port is configured for
10Mbps operation in half-duplex mode.
When selecting a Mode setting, the following points apply:
When a twisted-pair port is set to Auto-Negotiation, the end node
should also be set to Auto-Negotiation to prevent a duplex mode
mismatch. A switch port using Auto-Negotiation defaults to half-
duplex if it detects that the end node is not using Auto-Negotiation.
This can result in a mismatch if the end node is operating at a fixed
duplex mode of full-duplex. To avoid this problem when connecting
an end node with a fixed duplex mode of full-duplex to a switch
port, disable Auto-Negotiation on the port and set the port’s speed
and duplex mode manually.
The only valid setting for the SFP ports is Auto-Negotiation.
Flow Control - This parameter reflects the current flow control
setting on the port. The switch uses a special pause packet to
notify the end node to stop transmitting for a specified period of
time. The possible values are:
