Chapter 6: Port Parameters
106 Section I: Basic Operations
Disabling autonegotiation may require that you manually configure a
port’s MDI/MDI-X setting using this option or that you use a crossover
cable.
Note
When a transceiver is inserted into an uplink slot and a link is
established, that slot becomes a primary uplink port and the
corresponding backup port, 23R or 24R, automatically transitions to
redundant uplink status. The speed and duplex mode of the
redundant port automatically transitions to Auto-Negotiate to match
the speed of the primary uplink port and you cannot configure the
MDI/MDIX crossover parameter.
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 116.
F - Force Renegotiation
This item prompts the port to autonegotiate with the end node. For
more information, see “Forcing Port Renegotiation” on page 117.
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 118.
