If you are configuring multiple ports and the ports have different
settings, the Port Configuration menu displays the settings of the
lowest numbered port. Once you have configured the settings of
the port, all of its settings are copied to the other selected ports.
4. Adjust the port parameters as desired. You adjust a parameter by
typing its number. This toggles the parameter through its possible
settings. The parameters are described below.
0 - Port Description
You use this selection to assign a name to a port. The name can be
from one to fifteen alphanumeric characters. Spaces are allowed,
but you should not use special characters, such as asterisks or
exclamation points.
1 - Status
You use this selection to enable or disable a port. When disabled,
a port will not forward frames.
You might want to disable a port and prevent it from forwarding
packets if a problem occurs with the node or cable connected to
the port. Once the problem has been fixed, you can enable the
port again to resume normal operation. You can also disable an
unused port to secure it from unauthorized connections.
Possible settings are:
Forwarding - The port will forward packets. This is the default
setting.
Disabled - The port will not forward packets.
2 - Negotiation
You use this selection to configure a port for Auto-Negotiation or
to manually set a port’s speed and duplex mode.
If you select Auto for Auto-Negotiation, which is the default
setting, the switch will set both speed and duplex mode for the
port automatically. The switch determines the highest possible
common speed between the port and its end node and sets the
port to that speed. This helps to ensure that the port and the end
node are operating at the highest possible common speed.
You should note the following concerning the operation of Auto-
Negotiation on a switch port:
❑ In order for a switch port to successfully Auto-Negotiate its duplex
mode with an end node, the end node should also be using Auto-
Negotiation. Otherwise, a duplex mode mismatch can occur. A
switch port using Auto-Negotiation will default to half-duplex if it
detects that the end node is not using Auto-Negotiation. This will
result in a duplex mismatch if the end node is operating at a fixed
duplex mode of full-duplex.
