Chapter 4: Port Configuration
58 Section I: Using the Menus Interface
Enabling and Disabling a Port
This procedure enables and disables a port. You may want to disable a
port and prevent packets from being forwarded if a problem occurs with
the node or cable connected to the port. After the problem has been fixed,
you can enable the port to resume normal operation. You can also disable
an unused port to secure it from unauthorized connections. The default
setting for a port is enabled.
To change the port’s status, perform the following procedure:
1. From the Main Menu, type B to select Basic Switch Configuration.
The Basic Switch Configuration Menu is shown in Figure 4 on page 32
2. From the Basic Switch Configuration Menu, type P to select Port
Configuration.
The Port Configuration Menu is shown in Figure 13 on page 56.
3. Type S to select Set Status.
The following prompt is displayed:
Set Status->Enter port number>
4. Enter the number of the port you want to enable or disable. You can
configure only one port at a time.
The following prompt is displayed:
Enable or Disable port n (E/D)>
5. Type E to enable the port or D to disable it. The default is enabled. A
disabled port immediately stops forwarding all ingress and egress
traffic until you enable it again.
The display is refreshed to show the port’s new status.
