[. . . ] · Name (open systems mode only) Enter a name for the port. The port names display in the Port Properties dialog box and elsewhere in the Product Manager to identify the port. NOTE: To identify port numbers for which you want to provide names, place the cursor over the ports in the Hardware View. As you move over a port, a label displays that identifies the slot number where the port is installed. To name ports in S/390 mode, use the Configure Addresses dialog box. · Blocked (opens systems mode only) Placing a check mark in the check boxes of this column blocks the operation of the port. To block ports in S/390 mode, use the Configure Addresses dialog box. · 10-100Km This column is for extended distance buffering. You can enable extended distance for a port even if it is not an extended distance port. However, enabling extended distance buffering on a port disables the ability for the port to send broadcast traffic. When you select this option, the port can support up to 60 buffer-to-buffer credits (BB_Credits) to handle link distances up to 100 km. This enables the port to process 2K frames from attached devices. If this option is not enabled, the port uses the BB_Credit (1-60) configured through the Operating Parameters dialog box. If a device is connected and logged in to the fabric when extended distance is enabled or disabled on the corresponding port, the switch will send OLS for 5 milliseconds to force the device to log in again and obtain the new BB_Credit value set for the port. 3­8 edge switch 2/16 product manager user guide Configuring the Switch · LIN Alerts A link incident (LIN) is a problem detected on a fiber optic link, such as the loss of light or invalid sequences. When a problem occurs, a LIN alert is sent to the Link Incident Log in the switch Product Manager. LIN alerts warn you that there is a link incident being detected through a port connection. Place or remove check marks in the check boxes in this column to enable or disable link incident alerts. The factory default is to enable LIN alerts. A link incident causes a yellow attention indicator (triangle) to display for the port in the Hardware View and in the alert column of the Port List View. Once a LIN occurs, you must acknowledge it by selecting the Clear Link Incident Alert option from the right-click menu for the port (Hardware View). A description of the alert displays in the Link Incident field of the Port Properties dialog box (refer to Figure 2­3 on page 2-9). If the check boxes in this column are not selected, no link incident indicators display in the Hardware View. Also, the Link Incident field of the Port Properties dialog box is blank and a link incident is recorded in the Link Incident Log. LINs are always logged in the Link Incident Log, regardless of the configuration. [. . . ] See also expansion port. SEL System error light.
