Port states
The port operational state refers to the actual port state and not to the administrative state you may have
assigned. The port administrative state refers to the user-requested state. For more information, see ”Port
operational states” (page 92). Port administrative states have two forms: the configured administrative state
and the current administrative state. For more information, see ”Port administrative states” (page 93).
Port operational states
To view the operational state of each port in the faceplate display, open the View menu and select View
Port States. Table 20 lists the possible operational states and their meanings.
Configured Type The port type saved in the switch configuration. To change, click in the
field and select an option from the drop-down list.
I/O Stream Guard The I/O Stream Guard option suppresses the Registered State Change
Notification (RSCN) messages on a port basis. I/O Stream Guard should
be enabled only on ports connected to initiator devices. To change, click
in the field and select an option from the drop-down list. The options are:
• Enable–Suppresses the reception of RSCN messages from ports for
which I/O Stream Guard is enabled.
• Disable–Allows free transmission and reception of RSCN messages.
• Auto–Suppresses the reception of RSCN messages when the port is
connected to an initiator device with an HBA. The default is Auto.
Device Scan The Device Scan feature queries the connected device during login for
FC-4 descriptor information. Disable this option only if the scan creates a
conflict with the connected device.
