Chapter 6: Port Parameters
110 Section I: Basic Features
through or crossover twisted pair cable when connecting any
network device to a port on the switch.
When a port is using autonegotiation to set its speed and duplex
mode, the only available setting for this option is Auto. The port
automatically sets its MDI/MDI-X setting.
But if you disable autonegotiation 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 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 option resets the selected port. For more information, see
”Resetting a Port” on page 120.
F - Force Renegotiation
This option prompts the port to autonegotiate with the end node.
For more information, see ”Forcing Port Renegotiation” on page
121.
D - Set Port Configuration to Defaults
This option resets all port settings to the default values. For more
information, see ”Resetting the Port Configuration to the
Defaults” on page 122.
5. After making changes, type R until you return to the Main Menu. Then
type S to select Save Configuration Changes.
