• Enter a value in the RX BB Credit column to set minimum and maximum allowable port BB

credit values. These values vary by Director.

If an invalid value is entered, an Invalid RX BB Credit error message is displayed. The

BB Credit value is validated as entered.

Click Activate and a RX-BB Credit Confirmation box is displayed. 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 Edge Switches have a switch-wide buffer pool. The Configure Ports

dialog box displays the total and available buffers at the bottom of the dialog box. When

information is changed in the RX BB Credit column, the buffer information is also updated. If

information is entered that exceeds the buffer pool and Activate is clicked, an error message

is displayed. Also, ports for the 24-Port Edge Switches can be individually configured

between 2–12, with a total number of port credits of 150.

Right-clicking in the RX-BB Credit column displays an RX BB Credits dialog box. For Edge

Switches without buffer pools, this dialog box allows you to select Set all, which sets all ports

to a single value, or Set all to maximum, which sets all ports to a maximum BB credit value.

For Edge Switches with buffer pools, this dialog box allows you to select Set all, which sets all

ports to a single value, or Distribute, which evenly distributes the pool buffers among all

ports. Clicking OK changes the values in the Configure Port dialog box. Clicking Activate

changes the values on the Edge Switch.

d. Select or clear the LIN Alerts check box to enable or disable LIN alerts for a port.

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

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

view, Port List view, and Port Card view; and a message is sent to configured e-mail

recipients. LIN alerts are enabled by default.

e. Click Type for a specified port and select generic port (G_Port), fabric port (F_Port), or

expansion port (E_Port) from the list box.

f. Click Speed for a specified port and select 1Gb/s, 2Gb/s, or Negotiate as the desired

setting, depending on the speed capability of the device to be plugged into the port.

TIP: Right-clicking in the Speed column allows you to select from a menu to set all ports to

1Gb/s, 2Gb/s, or Negotiate.

g. Select a Port Binding check box to enable WWN binding for the selected port. This 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 check box cleared, any device

can attach to the port even if a WWN or nickname is specified in the Bound WWN column.

Enter a world wide name (WWN) in the Bound WWN box in the proper format

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

application. The device with this WWN or nickname will have exclusive attachment to the
