The Configure Ports dialog box is displayed (Figure 25).

a. Select a blank Name box and enter a descriptive port name of 24 or fewer alphanumeric

characters. Use a name that reflects the device connected to the port.

b. Select or clear the Blocked check box to block or unblock a port.

A check mark in the box indicates the port is blocked. Blocking the port prevents the

attached device from communicating with the Edge Switch. A blocked port continuously

transmits the offline sequence (OLS).

credit values. These values vary by Director.
