Chapter 6: Port Parameters
116 Section I: Basic Operations
When a port is using Auto-Negotiation to set its speed and duplex
mode, the only available setting for this item is Auto. The port
automatically sets its MDI/MDI-X setting.
If you disable Auto-Negotiation on a port and set a port’s speed and
duplex mode manually, the auto-MDI/MDI-X feature is also disabled. A
port where autonegotiation has been disabled defaults to MDI-X.
Disabling Auto-Negotiation may require that you manually configure a
port’s MDI/MDI-X setting using this option or that you use a crossover
cable.
The final three parameters on the Port Configuration menu are:
X - Reset Port
This item resets the selected port. For more information, see
“Resetting a Port” on page 125.
F - Force Renegotiation
This item prompts the port to autonegotiate with the end node. For
more information, see “Forcing Port Renegotiation” on page 126.
D - Set Port Configuration to Defaults
This item resets all port settings to the default values. For more
information, see “Resetting the Port Configuration to the Defaults” on
page 127.
