
Discovered Ports – The number of mapped and unmapped ports found during
discovery by the Emulex adapter driver. The mapped ports are targets and the
unmapped ports are non-targets such as switches or adapters.

Port Type – The current operational mode of the selected adapter’s port.

Enable PFC Throttle checkbox – PFC throttle is enabled by default to prevent
the loss of FCoE packets. Uncheck the box to disable PFC throttle.
Note: The checkbox does not appear if the adapter does not support PFC
throttle.

OS Device Name – The platform-specific name by which the selected adapter is
known to the operating system.

Symbolic Node Name – The FC name used to register the driver with the name
server.

Supported Class of Service – A frame delivery scheme exhibiting a set of
delivery characteristics and attributes. There are three classes of service.

Class 1 provides a dedicated connection between a pair of ports with
confirmed delivery or notification of non-delivery.

Class 2 provides a frame switched service with confirmed delivery or
notification of non-delivery.

Class 3 provides a frame switched service similar to Class 2 but without
notification of frame delivery or non-delivery.

Supported FC4 Types – A 256-bit (8-word) map of the FC-4 protocol types
supported by the port containing the selected adapter.
Port Status Area Field Definitions

Link Status – The status of the link on the selected adapter port.

Port Speed – The current port speed of the selected adapter port.

Bandwidth Limit – The QoS bandwidth restriction on the port.
Viewing FC/FCoE Port Statistics
When you select an FC/FCoE port from the discovery-tree, the Port Statistics tab
provides cumulative totals for various error events and statistics on the port. Some
statistics are cleared when the adapter is reset.
To view FC port statistics:
1. Select Host or Fabric view.
2. Select an FC/FCoE adapter port in the discovery-tree.
