Configuring the Director • Blocked-If the box is checked, the port is blocked. Blocked ports continuously transmit offline sequences (OLS), but cannot communicate to an attached device. If the box is not checked, the port is unblocked. • Port connection array-This yellow area of the dialog box is a matrix of port addresses that is used to configure connections between port addresses. All port addresses for the switch are listed along the top and left side of the matrix. The intersection between a vertical and horizontal row of cells (squares) is where you can either allow or prohibit connections between two addresses when you click the cell to prohibit connection or right-click the cell and display a menu of attributes. NOTE: For the Director 2/140, port addresses 84-87 contain X's. These refer to the internal ports 128-131, which cannot have external fiber cable connections. The default state of a cell is an empty cell (square), which represents an allowed connection. The symbol for a prohibited connection is shown in Figure 3-7. Click a cell to add the prohibited symbol and prohibit connection to that cell. To remove the prohibit symbol, click the cell again. Figure 3-7: Prohibited Port Connection symbol Move your cursor over the squares in the array to display the corresponding address. Right-click the array to display the following menu options: - Prohibit row-Prohibits connection between all addresses in a row. In effect, this prohibits connection between a specific address and all other port addresses. - Allow row-Allows connection for all port addresses on a row that are currently prohibited. This allows connection between a port with a specific address and other allowed ports. - Prohibit all-Prohibits connection between all port addresses. In this state, ports in the switch cannot connect with any other port address. - Allow all-This allows a dynamic connection through all port addresses from which connection is currently prohibited. The allowed attribute has the lowest precedence and does not override any other attribute. - Block all ports-Blocks communication between all ports. Ports that are blocked continuously transmit offline sequences (OLS). 3-18 director product manager user guide
