Configuring the Switch
Configure Ports
Use the procedures in this section to configure names, blocked and unblocked state,
10-100 km extended distance buffering, enable or disable link incident (LIN) alerts for
ports, port type, port speed, Port binding, and WWN binding name.
Port configuration data is stored in NVRAM on the Switch. Configure data in the
following columns of the Configure Ports dialog box:
• Port # — You cannot edit this field. This column identifies the port number. The
port numbers range from 0 through 31.
• 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 message 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 (open 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 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
milliseconds 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.
