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 can also disable an
unused port to secure it from unauthorized connections.
Possible settings are:
Enabled - The port will receive and forward packets. This is the
default setting.
Disabled - The port will not receive or forward packets.
Set [M]ode
You use this selection to manually configure a port’s speed and
duplex mode.
Auto-Negotiation is the default setting. In the Auto-Negotiation
setting, the switch will set both speed and duplex mode for the
port automatically.
The additional selections are displayed in the command prompt:
Enter new mode for port 1 (a/h/H/f/F/t/T)>
The possible settings for this selection are:
❑ a - Auto (Auto-Negotiation)
❑ h - 10-HDx (10 Mbps, half-duplex)
❑ H - 100-HDx (100 Mbps, half-duplex)
❑ f - 10-FDx (10 Mbps, full-duplex)
❑ F - 100-FDx (100 Mbps, full-duplex)
❑ t - 1000-HDx (1000 Mbps, half-duplex)
❑ T - 1000-FDx (1000 Mbps, full-duplex)
Note
Ports 11 and 12 are automatically set to the default setting of
1000-FDx.
Set [F]low Control
Flow control applies only to ports operating in full-duplex mode.
The switch uses a special pause packet to stop the end node from
sending frames. The pause packet notifies the end node to stop
transmitting for a specified period of time.
Possible settings are:
Disabled - No flow control on the port.
