# SANbox2-64 Port Properties

The Port Properties window enables you to view and change properties for the selected ports.

Port States (Administrative)

The administrative port state is the state requested by the user in the Port Properties window.

Online | Port is online
Offline | Port is offline
Test | Port is being tested

Port States (Operational)

The operational port state is reflected in the faceplate display, and refers to the actual state of the port, regardless of the administrative port state requested by the user in the Port Properties dialog. To view the operational state of a port, open the View menu and select View Port States.

On | Online - port is active and ready to send data
Ia | Inactive – port operational state is offline, but administrative state is online.
Iso | Isolated – E_Port has lost its connection.
Off | Offline - port is active, can receive signal, but not allowed to be logged in.
Tst | Test - port is active and being tested
Dn | Down – the port is inactive or shut off, not receiving a signal, and can’t be logged in

F | Fabric Port | Supports a single public device (N_Port)
FL | Fabric Loop Port | Self discovers a single device (N_Port) or a loop of up to 126 public devices (NL_Port).
TL | Translated Loop Port | Supports a loop of up to 124 private target devices capable of communicating with up to 63 off-loop initiator devices.
G | Generic Port | Self discovers as an F_Port or an E_Port
GL | Generic Loop Port | Self discovers as an F_Port, FL_Port, or an E_Port

E_Ports BB Credits

Port buffer credits can be changed on ports to accommodate connections to non-SANbox2-64 switches that have different port buffer capacities.

I/O Stream Guard

The I/O Stream Guard feature suppresses Registered State Control Notification (RSCN) messages on a port basis.

Enable | Enables RSCN suppression
Disable | Disables RSCN suppression. This is the default.

Device Scan

The Device Scan feature queries the connected device during login for FC-4 descriptor information. Disable this parameter only if the scan creates a conflict with the connected device.

Enable | Enables device scan feature
Disable | Disables device scan feature

Note: The switch monitors a set of port errors and generates alarms based on user-defined sample intervals and thresholds. The Enable All Alarm Thresholds checkbox in the Alarm Threshold Configuration window is the master enable/disable parameter for all events. Enables (True) or disables (False -the default) the generation of all enabled event alarms. Refer to the Configuring Alarms procedure for detailed information on excessive port errors and alarms.
