Configuring the Switch
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 NV-RAM on the switch. Configure data in the
following columns of the Configure Ports dialog box:
You cannot edit this field. This column identifies the port number. The port
numbers range from 0 through 15.
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
To block ports in S/390 mode, use the Configure Addresses dialog box.
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
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.
