100M/Half - 100 Mbps in half-duplex mode
10M/Half - 10 Mbps in half-duplex mode
1000 Mbps, full-duplex
When you choose a setting, note the following:
ˆ When a twisted pair port is set to Auto-Negotiation, the default
setting, the end node should also be using 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.
ˆ The only valid setting for an optional SFP port is Auto-Negotiation.
Flow Ctrl
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:
Enabled - The port is allowed to use flow control. This is the default
setting for all ports on the switch.
Disabled - The port does not use flow control.
