Configuring the Director 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 message displays that identifies the slot number where the port is installed. To name ports in FICON management style, use the Configure Addresses dialog box. ■ Blocked (open systems management style only)-Placing a check mark in the check boxes of this column blocks the operation of the port. To block ports in FICON management style, 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 choose 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 ms to force the device to log in again and obtain the new BB_Credit value set for the port. ■ 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, Port Card View, and in the alert column of the Port List View. Once a LIN occurs, you must acknowledge it by choosing 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 85). 128 Director Product Manager User Guide

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 message
displays that identifies the slot number where the port is installed.
To name ports in FICON management style, use the
Configure Addresses
dialog box.
Blocked (open systems management style only)—
Placing a check mark in
the check boxes of this column blocks the operation of the port.
To block ports in FICON management style, 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 choose 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
ms to force the device to log in again and obtain the new BB_Credit value set
for the port.
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
,
Port Card View
, and in the alert column of the
Port List View
. Once a LIN occurs, you must acknowledge it by choosing 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 85).
