7. Selected Ports Panel

This panel displays the ports that have been actively selected for use in the test configuration.

• Port Name

  The name (ID and type) of the port.

• Port Speed

  The physical port speed to use in the test. Normally this should be left at the default AUTO value, but certain DUTs require that the port speed is fixed to a specific rate.

• IP Address

  The IP address that you want to use for the port. All ports in the configuration need an IP address.

• Prefix

  The decimal network prefix for the address.

• Gateway Address

  The gateway address for the assigned IP address. Usually this will be the address of the DUT port which the test port is connected to.

• Protocol Segment Profile

  The protocol segment profile to use for this port. Profiles can be created, edited and deleted in the separate Protocol Segment Profiles panel.

Below the grid view is a section with less-frequently-used settings:

• Inter-Frame Gap

  Specifies the minimum gap between frames generated for a port, expressed as a number of bytes.

• Speed Reduction

  Specifies an optional speed reduction on the transmit side of the port, expressed as a ppm value.

• Enable PAUSE Mode

  Controls whether the port responds to incoming PAUSE frames.

• Enable Auto Negotiation

  Controls whether auto-negotiation for the port is enabled or not.

• MDI/MDIX Mode

  Controls MDI/MDIX Mode

• BBR Mode

  Control BroadR-Reach mode

It is possible to change settings on multiple ports at the same time by selecting multiple ports in the grid view and then changing settings in either the grid view or the detailed settings panel below the grid. The only setting that does not allow this is the IP address field, as this must always be a unique value.
