Click OK to change the values in the Configure Port dialog box.

Click Activate to change the values on the director.

An RX BB Credit Confirmation box displays.

In addition to the maximum BB-Credit limit per port, the total BB_Credits allocated to all ports

cannot exceed the buffer pool size.

NOTE: Only 24-Port switches have a switch-wide buffer pool. The Configure Ports dialog box

shows the total and available buffers at the bottom of the dialog box. When you change

information in the RX BB Credit column, the buffer information automatically updates. Ports for the

24-Port switches can be individually configured between 2-12, with a total number of port credits of

150.

e. Select the LIN Alerts box to enable or disable LIN alerts for a port.

A check in the box indicates alerts are enabled. When the feature is enabled and an

incident occurs on the link, an alert indicator (yellow triangle) appears at the Hardware

View, Port List View, and Port Card View pages, and a message is sent to configured e-mail

recipients. LIN alerts are enabled by default.

f. Select a Type box and select generic port (G_Port), fabric port (F_Port), or expansion port

(E_Port) from the list. If F_Port or E_Port is selected, the port will only operate as the port type

selected. If G_Port is selected, the port type is automatically detected and will operate as an

E_Port or F_Port.

g. Click the Speed box for a port.

A Speed list appears.

Select 1Gb/sec, 2Gb/sec, or Negotiate as the desired setting depending on the speed

capability of the device to be plugged into the port. A right-click in the Speed column allows

selecting from a pop-up menu to set all ports to 1Gb/sec, 2Gb/sec, or Negotiate.

h. Click the Port Binding box to enable WWN binding for the port, which allows only a specific

device to attach to the port.

This device is specified by the WWN or nickname entered into the Bound WWN column.

With the box cleared, any device can attach to the port even if a WWN or nickname is

specified in the Bound WWN column.

i. In the Bound WWN box, enter a world wide name (WWN) in the correct format

(xx.xx.xx.xx.xx.xx.xx.xx) or a nickname configured through the Element Manager.

If Port Binding is enabled, the device with this WWN or nickname has exclusive attachment

to the port. If Port Binding is enabled but an invalid WWN or nickname is entered in this

box, no device can connect to the port. If a valid WWN or nickname is entered but the Port

Binding is not checked, the WWN or nickname is stored and all devices can connect to the

port.

2. Use the vertical scroll bar as necessary to display additional port information rows (up to 64

ports).

3. Click Activate to save the configuration information and close the dialog box.
