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 necessary. You adjust a parameter by
typing its number. The parameters are described below.
Note
A change to a parameter is immediately activated on the port.
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. (You cannot set a port name if you are
configuring more than one port.)
1 - Status
You use this selection to enable or disable a port. When disabled,
a port will not forward frames to or from the node connected to
the port.
You might want to disable a port and prevent packets from being
forwarded 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 might also want to disable a port that is not being used to
secure it from unauthorized connections.
Possible settings for this parameter are:
Enabled The port will forward packets. This is the default
setting.
Disabled The port will not forward packets.
2 - Broadcast Filter
Most frames on an Ethernet network are usually unicast frames. A
unicast frame is a frame that is sent to a single destination. A node
sending a unicast frame intends the frame for a particular node on
the network.
Broadcast frames are different. Broadcast frames are directed to
all nodes on the network or all nodes within a particular virtual
LAN. Broadcast packets can perform a variety of functions. For
example, some network operating systems use broadcast frames
to announce the presence of devices on a network.
