Configuring ports
Use the Configure Ports dialog box to configure names, blocked and unblocked state, 10–100 km
extended distance buffering, enable or disable LIN alerts for ports, port type, port speed, port
binding, and the bound WWN.
NOTE: The Configure Ports dialog box is different for FICON and Open Systems management
styles. Those options available in Open Systems management style only are labeled as such.
The Port Binding feature must be installed before the Port Binding and Bound WWN columns can be
used. See ” Configuring the Open Systems Management Server ” on page 136 to install the Port
Binding feature.
Port configuration data is stored in NV-RAM on the switch. Configure data in the following columns
of the Configure Ports dialog box:
• Port #—You cannot edit this field. The physical port number, from 0-63 on the Director 2/64,
and 0-127 and 132-143 on the Director 2/140. Note that for the Director 2/140, ports
128-131 are internal ports and not available for external connections.
• Name (Open Systems management style only)—Enter a name for the port. The port names
display in the Port Properties dialog box and elsewhere in the Element Manager to identify the
port.
NOTE: To identify port numbers for which you want to provide names, place the mouse pointer
over the ports in the Hardware view. As you move over a port, a message is displayed 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 select
this option, the port can support up to 60 buffer-to-buffer credits (BB_Credits) to handle link
distances up to 100 km. If this option is not enabled, the port uses the BB_Credit (1–60)
configured through the Configure Fabric 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.
