7 - Speed
This item is only available when Negotiation is set to Manual. Type 7 to
toggle between the following selections:
10 Mbps
100 Mbps
1000 Mbps (Applies only to 1000Base SFP and GBIC modules. This
selection should not be used. An SFP or GBIC module should use
Auto-Negotiation to set its speed and duplex mode.)
8 - Duplex
This item is only available when Negotiation is set to Manual. The
possible settings are full-duplex and half-duplex.
9 - MDI Crossover
This item is only available when Negotiation is set to Manual.
This selection sets the wiring configuration of a twisted pair port. The
configuration can be MDI or MDI-X.
The twisted pair ports on the switch feature auto-MDI/MDI-X. They
configure themselves automatically as MDI or MDI-X when connected
to an end node. This allows you to use a straight-through twisted pair
cable when connecting any network device to a port on the switch.
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 Auto-Negotiation 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 136.
F - Force Renegotiation
This item prompts the port to autonegotiate with the end node. For
more information, see “Forcing Port Renegotiation” on page 137.
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 Default
Settings” on page 138.
