3.7.1 Enabling or Disabling a Port

The enabling or disabling of a port is a manual operation that can be used to isolate a network device that might be causing problems on the network, or to prevent unauthorized use of a port or station.

Note: A manual operation such as this can be performed only when auto-negotiation is set to manual mode. See “Configuring a Port Manually” below.

To enable or disable a port, use the following procedure:

1.Access the Port Configuration Menu by typing p in the Configuration Menu.

2.If necessary, select which unit to be configured on the System Unit Map and press Enter.

3.To select the port you want to enable or disable, type s, n, or p in the Basic Port Configuration Menu.

4.To toggle the port’s connection to either enabled or disabled status, type t.

5.To configure ports on another unit in the stack, type u to select the unit.

The port’s status is changed immediately, and it is reflected in the Port Configuration Menu’s Port Status indication and the Operating Status symbol for the port.

Important! Be careful not to disable the port to which the configuration computer is connected. This will disconnect the computer from the switch and prevent further configuration of the switch. Likewise, be cautious about disabling uplink ports on the switch.

3.7.2 Configuring Auto-Negotiation

Auto-negotiation is a feature of the Fast Ethernet standard that enables two devices on a common segment to communicate their transmission speed capabilities. This feature allows the devices to determine and use their highest common speed and best communication parameters.

Important! By default, all of the ports are set to Auto-Negotiation.

To set a port to manual-setting mode, or to re-enable auto-negotiation, use the following procedure:

1.Access the Port Configuration Menu by typing p in the Configuration Menu.

2.If necessary, select which unit to be configured on the System Unit Map and press Enter.

3.To select the port for which you want to set the auto-negotiation mode, in the Basic Port Configuration Menu, type s, n, or p.
