Help on Data Protection > NDMP > Ports
The following information and controls are available at .
- Ports
- This table lists the ports on each Backup Accelerator node and shows how the ports interact with the connected NDMP backup devices.
- LNN
- Specifies the logical node number of the Backup Accelerator node.
- Port
- Specifies the name of the Backup Accelerator node and the port number.
- Topology
- Specifies the type of Fibre Channel topology that the port is configured to support.
- Point to Point
- Specifies a single backup device or Fibre Channel switch that is directly connected to the port.
- Loop
- Specifies multiple backup devices that are connected to a single port in a circular formation.
- Auto
- Automatically detects the topology of the connected device. This is a recommended setting and is required if you are using a switched-fabric topology.
- WWNN
- Specifies the world wide node name (WWNN) of the port. This name is the same for each port on a given node.
- WWPN
- Specifies the world wide port name (WWPN) of the port. This name is unique to the port.
- Rate
- Specifies the rate at which data is sent through the port. The rate can be set to 1 Gb/s, 2 Gb/s, 4 Gb/s, 8 Gb/s, and Auto. The 8 Gb/s setting is available only for A100 nodes. If set to Auto, OneFS automatically negotiates with the DMA to determine the rate. Auto is the recommended setting.
- Actions
- Enable or disable a port.
