# Configuring a Port

Configuring a port involves defining the port mode. For public devices and other switches, a switch automatically sets the port mode as each port discovers the type of device to which it is connected.

To change the port settings, do the following:

1. In the faceplate display, select the port(s) to change.

2. Open the Port menu and select Port Properties to open the Port Properties dialog.

3. Click the new port state, speed (SANbox2 and SANbox2-64 ), and mode radio buttons.

4. Click the I/O Stream Guard (RSCN suppression) radio button.

5. Enter a value (0-255) in the E_Port BB Credits (SANbox2 and SANbox2-64) field.

6. Click the OK button to save the new port settings to the switch.
