Monitoring and Managing the Switch
80 Edge Switch Element Manager User Guide
■ Node Type (Edge Switch 2/24 only)—The node type:
— N_Port—The switch port is operating as an F_Port.
— NL_Port—the switch port is operating as an FL_Port
■ Port WWN—The port WWN of the attached node (N_Port). The 16-digit
WWN is a set of unique numbers assigned to the device attached to the port.
The WWN is prefixed by the manufacturer’s name of the host bus adapter that
attaches to the device. If there is a nickname assigned, the nickname displays
instead of the WWN. For private loop devices,
Not Logged In displays.
■ Unit Type—The following information, if supported, is supplied by the
attached device:
— Converter
— Gateway
— HBA
— Module
— Other
— Proxy-agent
— Storage device
— Software driver
— Storage subsystem
— Switch
— Unknown
Note: The Unit Type comes directly from the device's sense ID when the device attaches
to the port during login. If the connection is lost to the device, the type will display as
Unspecified
, because the device is no longer logged into the port. When the device
logs back in, the unit type updates.
■ BB_Credit—The BB_Credit supported by the device. This field is left blank
for all loop devices.
